Rock Krawler JL35X2PLA-4TR X-Factor X2 Pro Elite Trail Runner 3.5" Long-Arm Suspension Lift Kit

The Rock Krawler JL35X2PLA-4TR is a 3.5-inch X-Factor X2 Pro Elite Trail Runner Long-Arm Suspension System engineered specifically for the 2018-present Jeep Wrangler JL Unlimited (4-Door) gas models. This is Rock Krawler's top-tier coilover-equipped long-arm lift system, purpose-built for serious rock crawling while retaining excellent on-road driveability.

X-Factor X2 Independent 3-Link Design:

The X-Factor platform delivers an independent 3-link suspension design front and rear, maximizing articulation and off-road performance. The proprietary geometry features a double-adjustable front and rear upper control arm that upgrades factory hardware to 14mm with a 2-3/8" mounting width and 1" Pro Krawler joints at each end. The rear suspension provides adjustable anti-squat with enhanced X2 rear instant center and roll center geometry for superior trail stability.

Pro Elite Billet Aluminum Lower Control Arms:

The "Pro Elite" designation signifies the inclusion of PB&J (Pure Beef and Jealousy) billet aluminum lower control arms — custom machined in-house from solid square billet aluminum stock. These arms are built to handle extreme off-road abuse while remaining maintenance-free. At the frame connections, the "Adventure Series" maintenance-free joint reduces grease points while providing excellent vibration absorption and proper joint misalignment capability off-road.

Trail Runner Coilover System:

This Trail Runner variant features 2-5/8" RRD Racing Coilovers with remote reservoirs front and rear, delivering a well-tuned package for both trail performance and street comfort. The Trail Runner configuration adds Fast CD (Compression Dampening) Adjusters for an even greater level of tunability, allowing the driver to fine-tune ride quality, handling, and off-road performance to their preference.
