🧾 Overview
The Bilstein B8 5100 Suspension Lift Kit is a high-performance suspension solution engineered specifically for 2018–2023 Jeep Wrangler JLU 4-door models. Designed to increase ground clearance, allow for larger tires, and improve wheel travel and articulation, this kit delivers balanced on-road comfort and confident off-road capability.
This system combines Bilstein B8 5100 monotube shock absorbers with custom-matched, longer-travel cold-wound coil springs to optimize the factory JLU suspension geometry without requiring additional correction components. The result is a clean, functional lift that avoids excessive wheel gap while maintaining ride quality and stability.
Providing approximately 2.5 inches of lift, this kit allows Rubicon models to run up to 35" tires and non-Rubicon models with stock fenders to run up to 33" tires. All components bolt directly into factory mounting locations, making this an effective and straightforward upgrade for daily driving and trail use.
