Rock Krawler Suspension JL45PNL-2S1 4.5 Inch X-Factor Pro No Limits Aluminum Mid-Arm Suspension System Stage 1

The Rock Krawler JL45PNL-2S1 is a premium 4.5-inch X-Factor Pro "No Limits" mid-arm suspension system designed specifically for Jeep Wrangler JL 2-door Rubicon models. This Stage 1 system delivers maximum articulation, superior on-road comfort, and hardcore off-road capability with the added benefits of lightweight 7075 aluminum control arms.

X-Factor Pro Aluminum Control Arms:

All eight control arms are constructed from solid 7075 billet aluminum, CNC-machined in-house for exceptional strength-to-weight ratio. The adjustable upper and lower control arms feature Rock Krawler's proven Pro-X Krawler Joints at the axle connections and maintenance-free Adventure Series joints at the frame connections, providing up to 95 degrees of total misalignment capability. This dramatically reduces the binding inherent in factory JL control arms while allowing precise tuning of caster and pinion angles front and rear.

No Limits Sway Bar Links:

The "No Limits" designation comes from the inclusion of specialized front sway bar links designed to work seamlessly with the factory electronic sway bar disconnect feature found on Rubicon models. These links feature CNC-machined billet aluminum center sections and Made in USA FK Bearing heim joints with factory-sized hardware for plug-and-play installation.

Triple-Rate Coil Springs:

Rock Krawler's industry-leading triple-rate coils provide 4.5 inches of lift while delivering exceptional on-road comfort that surpasses factory linear-rate springs. The coils are engineered with proper free-length for maximum off-road articulation while staying firmly seated in the coil buckets. All four coils work together to provide controlled reactions to bumps, rocks, sand, and mud whether you're on the street or trail.

Complete Geometry Correction:

• Correction pads to reduce spring bow inherent in factory setup
• Track bar geometry corrections front and rear for perfectly centered axles
• No compromise in on-road handling or stability
• Optimized for 35-40 inch tire fitment depending on configuration

What's Included in Stage 1:

• Eight 7075 aluminum adjustable control arms with Pro-X Krawler and Adventure Series joints
• Four triple-rate coil springs (4.5" lift height)
