Skyjacker Long Travel 2 Stage 3.5in-4in Coil System(black) Jeep Wrangler JL 4 Door 4WD (Non-Rubicon)

Part #:JL40BPBLT

All Skyjacker systems for the NEW Jeep Wrangler JL 4-Door 4WD feature DUAL RATE-LONG TRAVEL coil springs to ensure superb highway ride quality and performance on rough terrain – whether it’s the streets you travel or when hitting the trails. The DUAL RATE-LONG TRAVEL coil springs offer the best of both driving worlds! What this means is the 1^st spring rate offers an exceptional highway ride AND the coils will expand while off-roading during extreme articulation as the suspension droops to keep the tires in contact with the ground much longer than a linear rate, or single rate, coil spring resulting in a smoother & more controlled ride while keeping the coil in the coil bucket at full droop. The 2^nd rate (lower coils) only engage after compression past the 1^st rate. This second rate allows consistent control and stability when heavy off-road suspension movement is required.

3.5-4 in. Lift Systems include both Front & Rear Extended sway bar end links that are very important to allow proper droop & long travel as well as front & rear bump stop extensions to make sure the suspension clears the tires at bump, Front Adjustable Track Bar (no pitman arm required) for proper steering geometry & axle centering, front & rear Eccentric Cam D-bolt alignment kits for proper caster correction & Rear Upper frame mounted Track Bar Relocation bracket with Grade 8 mounting hardware. Long Travel front & rear shocks are length fitted to offer the maximum extension allowable for full articulation to complete this total system package.
