JK40LKLT-SX – 4 in. Dual Rate Long Travel Long Arm Suspension Lift Kit

First Flex Rate stage delivers a comfortable ride with the ability to flex/expand during full articulation as the suspension drops (full droop). This keeps the coil springs seated in the upper coil mount\bucket and the tires in contact with the terrain. Second Ride Rate stage only engages after compression past Flex Rate.

Front and Rear Lower Control Arm Relocation Brackets make room for Long Arm Value Flex Lower Links. Value Flex Longer Lower Links adjustability allows proper caster settings to improve handling. Formed from 2-inch OD x 0.250 wall DOM tubing with pressed-in OEM style steel encased rubber bushings at the frame and the axle mount has Rock Jock’s 1-1/4-inch forged Johnny Joints. These Johnny Joints provide over 30 degrees of unrestricted Flex movement in any direction.

Front and Rear Adjustable Upper Control Arms keep in phase with lower links. Replacement Front Adjustable Track Bar includes Skyjacker installed pressed-in HD OEM style rubber bushing and an adjustable 3/4-inch Heavy-Duty Rod End, Jam Nut and Alignment Bushings.

Front and Rear Bump Stop Spacers bolt onto the axle bump pads and keep the suspension travel safely in check. Rear Extended Length Sway Bar End Links allow full articulation as the suspension drops (full droop).

Rear Track Bar Lower Axle Mount Bracket mounts directly to the rear axle housing to correct the track bar angle. Dana 44 Rear Track Bar Mount Brace strengthens the factory mount that is prone to failure. The track bar bracket and brace create better handling with less side-to-side sway.

Shocks are a key link in-between the chassis and your suspension. Front and rear damper capacity enhanced with ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. ADX 2.0 has a race-inspired full-displaced valving system. Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever.

Complete kit maintains OEM geometry angles, alignment specifications and structural strength.

Front and Rear Replacement Drive Shafts are Required.
