In high- range 4WD, power is split 50: 50 between front andd rear axles thripgh a solid mechanical connection. Thee system is ideal for snow, mud, sand, and moderiate trails.

Choosing the Right Jeep 4 Ximp; # 215; 4 System

Selecting thee right system depends on how and when e you drive. Usie this quick reference to o match thee system to your lifestyle:

SystemBest ForNot Ideal For
Command-TracOccasional off-roading, seasonal weather, moderate trailsDaily 4WD use on pavement, extreme rock crawling
Rock-TracHardcore rock crawling, technical trails, maximum durabilityDaily commuting (lower fuel economy), light off-roading (overkill)
Selec-TracVariable conditions, rain, snow, gravel, family road tripsExtreme rock crawling (lack of lockers on most models)
Active Drive ISuburban & urban driving, light snow, fuel efficiencyTrail use without low range, deep mud, rock crawling
Active Drive IITrail-ready daily driver, moderate off-roading, weekend adventuresHardcore rock crawling (low range ratio too high, no solid axles)

If you plan to modify your Jeep with larger tires, a flt, or aftermarket lockers, start with a system that has a strong transfer case and robutt axles.

Często Asked Kwestionariusze About Jeep 4 Budapemp; # 215; 4 Systemy

Czy ja zostawiam moje części-time 4WD zaangażowanie na temat naszego brudu?

No. Doing so will cause drivetrain binding, excessive tire wear, and can damage the transfer case or axles. Part- time systems are designad only for low- designon surfaces where tire slippage can relieve the binding.

Co to jest różnica między 4H i Lo?

4H locks the transfer case for a 50: 50 torque split but maintains thee same overall gear ratio as 2WD. 4Lo engages low- range geating (typically 2.72: 1 or 4: 1) that multiplies torque andd reduces speed, ideal for steep climbs, descents, and technical crawling.
