Why Install Tube Doors on Your Jeep?

Tube doors offer a unique blend of open-air driving freedom and essential side protection. Unlike full factory doors, they reduce weight and give you an unobstructed view of the trail while still providing a physical barrier that keeps you and your passengers from sliding out. Many Jeep owners install tube doors to enhance the vehicle’s rugged look, improve airflow on hot days, and simplify entry and exit during off-road adventures. Before you start, it’s important to understand that proper installation is key to safety and longevity. This guide walks you through every step, from gathering tools to making final adjustments.

Tools and Parts You Will Need

Before you begin, assemble all the necessary equipment. Using the correct tools saves time and prevents damage to your new tube doors.

  • Tube doors kit specific to your Jeep model – Make sure the kit includes hinges, bolts, and any required adapters. Confirm compatibility with your Jeep’s year and model (e.g., TJ, JK, JL, or JT).
  • Socket wrench set – Typically you will need metric sockets (10mm, 13mm, 15mm). A ratchet with a long extension can help reach tight spaces.
  • Torque wrench – Critical for tightening hinge bolts to factory specifications. Overtightening can strip threads or crack hinge brackets.
  • Allen wrenches (hex keys) – Some kits use hex-head set screws or bolts.
  • Phillips and flathead screwdrivers – For prying plastic trim or adjusting set screws on hinges.
  • Rubber mallet – Useful for gently tapping stubborn hinge pins or aligning brackets without marring the finish.
  • Safety glasses and work gloves – Protect your eyes and hands from metal edges and particles.
  • Thread-locking compound (Loctite or similar) – Most tube door kits recommend blue Loctite on hinge bolts to prevent loosening from vibration.
  • Penetrating oil (e.g., WD-40 or PB Blaster) – Helps loosen seized factory hinge bolts if needed.
  • Clean rags and rubbing alcohol – For cleaning hinge mounting surfaces before installation.

Preparation: Removing Your Factory Doors

Proper preparation ensures a smooth installation and protects your Jeep’s paint and finishes.

Step 1: Park on Level Ground and Disconnect Electrical (If Applicable)

Engage the parking brake and place wheel chocks. If your Jeep has power windows, mirrors, or locks, you will need to disconnect the wiring harness inside the factory door. Consult your owner’s manual for the correct procedure. On most Wrangler models (JK, JL, JT), there is a plastic connector near the hinge area that you press to release. Wrap the connector in a plastic bag and tape it to the body to keep it dry and secure.

Step 2: Remove the Factory Door

  • Open the door fully and support it from underneath (a rolling stool or helper works well).
  • Remove the door check strap by unscrewing the bolt that holds it to the body.
  • Using a socket wrench, remove the top and bottom hinge bolts. On some models, you may need to loosen the hex nuts on the inside of the door.
  • Carefully lift the door up and off the hinges. Set it aside on a soft surface to avoid scratching the paint.
  • If you plan to reinstall factory doors later, store the hinges and bolts in a labeled bag.

Step 3: Inspect and Clean the Hinge Mounts

Look for rust, bent brackets, or damaged threads. Use penetrating oil on any stubborn bolts. Clean the hinge mounting surfaces with rubbing alcohol to remove wax, grease, or dirt. A clean surface ensures the new tube door hinges sit flush and do not squeak over time.

Installing the Tube Doors: Step-by-Step

The following steps apply to most aftermarket tube door kits. Always refer to the instructions included with your specific kit, as hardware layout can vary.

Step 1: Test-Fit the Hinges

Before bolting anything permanently, hold each hinge bracket against the factory hinge mount on the Jeep. Check that the holes align and the bracket sits flat. If your kit includes shims or spacers, use them to correct any gap between the bracket and the body. This is especially important on older Jeeps where body mounts may have settled.

Step 2: Attach the Upper and Lower Hinges to the Door

Lay the tube door on a padded surface with the hinge side up. Insert the hinge pins through the door’s hinge sleeves and secure them with the provided bolts or set screws. Do not tighten fully yet – leave them loose enough to allow adjustment during installation. Apply a drop of blue Loctite to each bolt thread.

Step 3: Mount the Door to the Jeep

  • With the hinges attached to the door, lift the door into position. Align the hinge brackets with the factory hinge mounts on the Jeep body.
  • Insert the hinge bolts from the kit through the hinge bracket and into the threaded holes on the side of the Jeep. On some models, you may need to use the original factory bolts if they are a better match for the thread pitch. Consult your kit’s instructions.
  • Hand-tighten all bolts to hold the door in place. Do not use tools yet.

Step 4: Align and Adjust the Door

This is the most critical step for proper fit. Close the door gently and check the gaps between the door and the fender, as well as between the door and the rear side panel. The door should sit evenly with even gaps on all sides. Look at the latch area: the door should meet the striker without forcing. If the door is too high or low, or tilted, adjust the hinge bolts slightly. Tap the hinge brackets gently with a rubber mallet to shift the door position. Once satisfied with alignment, tighten all hinge bolts to the torque specification provided in the kit (typically 25–35 ft-lbs for M10 bolts). Recheck alignment after torquing.

Step 5: Install the Latch Mechanism (if included)

Many tube doors come with a simple pin latch or a push-button mechanism. Attach the latch to the door using the supplied hardware. Adjust the striker pin on the door jamb so the latch closes smoothly and securely. Test the latch several times to ensure it releases fully. For daily driving, a latch that is too tight may be difficult to open; too loose will rattle.

Step 6: Repeat for the Passenger Side

Follow the same procedure for the opposite door. It can be helpful to compare gaps between the two sides to ensure symmetry.

Final Adjustments and Safety Checks

After both tube doors are installed, perform a thorough check before taking your Jeep on the road.

  • Check door operation: Open and close each door several times. They should swing freely without binding.
  • Verify latch engagement: With the door closed, try to push the door outward from inside. The latch should hold firmly with minimal play.
  • Torque check: After the first 20–30 miles of driving, re-torque all hinge bolts. The vibration of initial driving can cause bolts to settle.
  • Test fit with soft top/fastback: If you have a soft top, roll down the windows and ensure the tube door does not interfere with the top’s frame or zipper.
  • Mirror mounting: Some tube door kits have threaded holes for attaching aftermarket mirrors. Install mirrors before driving; check local laws regarding side mirrors for vehicles with factory mirrors removed.

Common Alignment Issues and Fixes

  • Door drops when opened: The hinge bolts may be too loose or the hinge pin bearing surface is worn. Add a thin washer between the hinge halves to take up slack.
  • Door rubs against fender flare: Loosen all hinge bolts, lift the door slightly, and retighten. If clearance is still tight, you may need to adjust the fender flare brackets or install spacer washers behind the hinge.
  • Latch won’t click shut: The striker may be too far in or out. Loosen the striker plate, shift it 1–2 mm, and retighten. Use a marker to outline the original position in case you need to revert.

Safety Considerations for Tube Doors

Tube doors provide side restraint but are not designed to replace full doors in a crash. They are primarily for off-road and low-speed use. However, many drivers use them on public roads. Here are key safety points:

  • Always wear seat belts. Tube doors offer minimal impact protection; the seat belt is your primary restraint.
  • Check local laws. Some states require full doors or doors with certain heights. Tube doors may not pass inspection if they lack a mid-height bar or latch. Research regulations in your area.
  • Secure loose items. A gap between the door and the body can allow small objects to fall out. Use cargo nets or storage bins for loose gear.
  • Children and pets. Tube doors with large openings may not prevent a child or pet from leaning out. Consider adding mesh covers or choosing a door with closer tube spacing.
  • Off-road caution: Low-hanging branches can snag inside the open door structure. Keep arms and elbows inside the vehicle’s silhouette.

Maintenance Tips to Extend the Life of Your Tube Doors

With basic care, tube doors will last for years without rust or rattle.

  • Regularly inspect bolts and hinges: At every oil change, check that all bolts are tight. Look for signs of corrosion on the hinge pins.
  • Clean after off-road trips: Mud, sand, and salt accelerate wear. Hose off the doors, paying attention to the hinge pockets and latch mechanism. Dry thoroughly with a microfiber towel.
  • Apply anti-seize or silicone spray: To prevent squeaking, spray silicone lubricant on hinge pivot points every few months. Avoid WD-40 as it can attract dirt.
  • Touch up scratches: Most tube doors have a powder-coated finish. Use a matching automotive touch-up paint or clear coat to seal exposed metal and prevent rust.
  • Store indoors if possible: During winter or extended storage, remove the tube doors and keep them in a dry garage. This protects the finish and hinge hardware from road salt.

Alternative Styles and Customization Options

While the standard half-tube design is the most popular, other options exist:

  • Full tube doors: Extend to the top of the door opening for added protection and a more enclosed feel. They work well with soft tops and provide better weather resistance.
  • Mesh or screen doors: Combine a tube frame with a tight mesh panel to keep out bugs while retaining airflow. Great for summer camping trips.
  • Steel vs. aluminum vs. plastic: Steel is stronger and heavier; aluminum is lighter and corrosion-resistant; plastic (ABS) is budget-friendly but less durable for hard off-roading.
  • Custom powder coating: Many manufacturers offer colors beyond black. You can match your Jeep’s paint or add a contrasting accent.

Where to Buy Quality Tube Doors

When purchasing, choose reputable brands that offer precise fitment and robust hardware. Read online reviews and check forums like JeepForum.com for owner feedback. Popular retailers include Quadratec, ExtremeTerrain, and Morris 4×4 Center. Be sure to verify the product fits your exact model year, as hinge spacing changed between the TJ (1997–2006), JK (2007–2018), JL (2018–present), and Gladiator JT.

Frequently Asked Questions

Can I install tube doors without removing the factory hinges?

Most tube door kits require you to use the factory hinge mounts on the body, but the factory door hinges themselves are not reused. You will remove the factory hinges (or unbolt the hinge portion from the body when swapping hinges). Some kits allow you to keep the factory hinges and simply replace the door; these are less common.

Do tube doors affect warranty?

Installing aftermarket parts generally does not void the vehicle warranty unless they cause damage. However, if a hinge bolt hole is stripped or a wiring harness is cut during removal, repairs may not be covered. Use care and keep all factory parts in case you need to revert to stock for warranty service.

How long does installation take?

For a first-timer, expect 1–2 hours per door, including removal of the factory doors. Experienced owners can do both sides in under an hour.

Do I need special tools for a JL or Gladiator?

The JL and JT use the same hinge mounting pattern, but the door check strap is integrated differently. You may need a T45 Torx bit or a 10mm socket to remove the check strap. Most kits include an adapter bracket for the newer door check system.

Final Thoughts

Installing tube doors is one of the most popular modifications for Jeep owners, and with good reason: it transforms the driving experience, especially in warm weather and on the trail. By taking the time to prepare, align, and maintain your doors, you’ll enjoy years of trouble-free use. Remember that no guide can replace the specifics of your kit, so always read the included instructions and reach out to the manufacturer if you encounter fitment issues. With the right approach, you’ll be ready to hit the roads with confidence, style, and a breeze on your face.
