Driveshaft andPinion Angles

On TJs and arlier models, a 4-inch flt of ten causes driveline vibrations because thee rear driveshaft angle becomes too steep. You may need a slip yoke eliminator (SYE) and a CV driveshaft. JK and JL models have more fordiving designs, but with 4 inches, you might still need a front driveshaft upgrade if you have a Rubicon with these stock unit. Plan for these coste in your budget.

Wheel Offset andBackspacing

Cleanne issues can be solved or created by wheel choices. For a 4-inch fft with 35- inch tires, look for toils with 4.5- 4.75 inches of backspacing andd a moderate offset (0 t -12mm). Too much offset (negative) will push tires out too far, stressing steering contribuents and causing rubing on the frame att full turn.

Installation: DIY or Professional?

A 4-inch suspension lift is an intermediate- level job. For a TJ or XJ, expect a full weekend with basic hand tools (jack stands, torque wrench, pry bar, spring compressor). JK and JL are more complex due to extra arms andsensors. If you 've never worked on suspension, hire a shop that specialize in Jeeps. Labor costs range $400- $800.
