Rock Krawler Suspension JL35XFP-4S1 3.5 Inch X-Factor Pro Aluminum Lift Kit Stage 1

The Rock Krawler JL35XFP-4S1 is a complete 3.5-inch X-Factor Pro Mid-Arm suspension system featuring all-aluminum control arms for maximum strength and weight savings with bolt-in installation. This Stage 1 system is engineered for Jeep Wrangler JL owners seeking exceptional off-road articulation combined with superior on-road comfort and handling.

Key Features:

• All 8 control arms machined from solid 7075 aluminum with X-Factor adjustability built in
• Adjustable upper and lower control arms offer 95 degrees of misalignment when paired with Pro-X Krawler Joints and Adventure Series joints
• Triple-rate coil springs deliver excellent on-road comfort superior to OEM linear rate springs
• Provides 3.5 inches of lift to clear up to 40-inch tires depending on model
• Maintenance-free Adventure Series joints at frame connections and PRO Krawler Joints at axle connections
• Includes correction pads to reduce factory spring bow and track bar geometry corrections front and rear for perfectly centered axles

The extensive adjustability allows precise tuning of caster and pinion angles front and rear, while the aluminum construction reduces unsprung weight for improved suspension response. This complete system eliminates the factory control arm bind and provides a comprehensive solution for both street driving and serious trail use.
