Rock Krawler JT45XFP-DTR 4.5-Inch X-Factor Pro Aluminum Trail Runner Lift System (Diesel)

The Rock Krawler JT45XFP-DTR is a 4.5-inch X-Factor PRO Aluminum Mid-Arm Trail Runner suspension system engineered specifically for diesel-powered Jeep Gladiator JT models. This complete, bolt-in lift system delivers class-leading articulation, precision geometry correction, and coilover performance both front and rear — all in one comprehensive package.

X-Factor PRO Aluminum Control Arms:

• All 8 control arms (upper and lower, front and rear) constructed from solid 7075 aluminum for maximum strength-to-weight ratio
• Fully adjustable upper and lower arms for precise caster and pinion angle tuning front and rear
• 95 degrees of total misalignment when paired with Pro-X Krawler Joints and Adventure Series joints
• Maintenance-free Adventure Series joints at all frame connections; PRO Krawler Joints at all axle connections
• Significantly reduces the inherent bind found in factory JT control arms

Trail Runner Coilover Shock System (Front & Rear):

• Front: 13-inch travel RRD 2.625 coilover shocks yielding 14.4 inches of front axle travel
• Rear: 12-inch travel RRD 2.625 coilover shocks yielding up to 15 inches of rear axle travel
• Coilovers provide an additional level of ride-height and damping tuneability

Diesel-Tuned Coil Springs:

• Triple-rate front coils and quad-rate rear coils tuned specifically for the added weight of the diesel drivetrain
• Springs are built with the proper free-length for off-road articulation and remain firmly seated in the coil bucket
• Delivers superior on-road comfort compared to OEM linear-rate springs

Complete Geometry Correction Package:

• Spring correction seats included to eliminate factory spring bow
• Front and rear track bar geometry corrections to precisely center both axles
• Corrected geometry ensures no compromise in on-road handling or highway stability

Warranty: All hard parts (control arms, track bars, and mounting brackets) are covered by Rock Krawler's abuse-proof lifetime guarantee — replaced if bent, broken, or functionally damaged. Joint housings carry a 10-year warranty. Shocks and springs are warranted against manufacturer defect.
