Rock Krawler JL35AS-4D Suspension System for Jeep Wrangler
Upgrade your 2018 Jeep Wrangler with the Rock Krawler JL35AS-4D 3.5 inch Adventure DIESEL Mid-Arm Suspension System. This complete, bolt-in kit is specially crafted for Sport and Sahara models, delivering unparalleled articulation and off-road performance that you can rely on whether you’re hitting the streets or tackling rugged trails.
Why Choose the JL35AS-4D?
The name "Adventure" reflects the system's robust design, featuring two non-adjustable control arms equipped with 100% Service Free Adventure Series joints. These mid-arms allow for an impressive 35 degrees of misalignment, minimizing the bind typically found in factory JL control arms. With longer arms than OEM, you can easily correct the caster for a smoother ride.
Comfort and Performance
Experience the perfect blend of comfort and capability with our TRIPLE RATE coils. Designed for optimal on-road handling, these coils outperform the standard linear rate springs, ensuring a controlled response to bumps, rocks, and whatever off-road challenges you face. Plus, the included correction pads help reduce spring bow, and track bar geometry corrections keep your axles centered for superior handling.
