Rock Krawler TJ45X2COMP-5S X-Factor X2 Flat Belly Coilover Long Arm Suspension System 4.5 Inch Lift with 5 Inch Stretch

The Rock Krawler TJ45X2COMP-5S is a 4.5-inch X-Factor X2 Flat Belly Coilover Long Arm Suspension System with 5-inch rear stretch, purpose-built for the Jeep Wrangler TJ. This is a comprehensive, weld-in suspension upgrade that represents a major evolution in long arm suspension design, delivering exceptional geometry, ground clearance, and on/off-road performance.

This Comp System configuration pairs front coilovers with a traditional rear coil and shock setup — the ideal combination for Wrangler owners who want the adjustability and performance of coilover racing shocks up front while retaining the ability to carry small loads or tow light trailers. The 5-inch rear stretch is achieved through longer upper and lower control arms, expanding the wheelbase for improved off-road capability.

X-Factor X2 Flat Belly Design:

• Full flat belly long arm system — all control arms tuck up inside the frame for maximum ground clearance
• Independent 3-Link front geometry with double-triangulated 4-Link rear suspension
• Enhanced X2 geometry with additional double triangulation at the rear for superior stability over the original X-Factor design
• Best-in-class crossover angles for unmatched off-road articulation

Joints & Hardware:

• Adventure Series Joints on the frame side of lower control arms for reduced maintenance and improved ride quality
• Pro-X Krawler Joints featuring one-piece BASF thermo-elastomer construction with 95+ degrees of misalignment tolerance on every control arm

Coil Springs & Shocks:

• Tuned Triple-Rate coil springs front and rear for balanced street and trail performance
• Front coilover shocks provide an additional level of tunability for ride height, handling, and off-road performance

Additional Features:

• Pro front sway bar disconnects included
• 99-inch wheelbase configuration with 5-inch rear stretch
• Upgradeable to full coilovers, additional stretch, or Rockzilla system
• Abuse-proof lifetime warranty on all hard parts

The Rock Krawler X-Factor X2 Flat Belly Long Arm System delivers an unmatched combination of ground clearance, ride quality, and tuned suspension performance — engineered to be the foundation for every build, whether on the street or the trail.
