Jeep Wrangler Suspension Lift Kit - Front + Rear - Skyjacker - 3.75in Comp. Box w/Dual Rate LT Coil Springs - 2021–2023. A purpose-built lift kit for JL 4XE non‑Rubicon Wranglers that adds 3.75 inches of lift using Skyjacker’s dual‑rate long travel coil springs to balance articulation and ride comfort.

This Skyjacker kit uses a progressive, variable‑rate coil spring with a 2‑stage design: a Flex Rate for improved articulation and tire contact during full droop, and a Ride Rate that engages under compression for controlled on‑road behavior. Rear coils are side‑specific to match the Wrangler’s handling. The package includes a replacement front adjustable track bar with Skyjacker‑installed pressed‑in HD OEM‑style rubber bushings and an adjustable 3/4‑inch heavy‑duty rod end with jam nut and alignment bushings, plus a heavy duty rear track bar upper mount bracket to help center the axle. Bump stop spacers and extended length sway bar end links are provided to protect travel and allow full articulation. The design works with the OEM Electronic Stability Control (ESC) and is a straight bolt‑on, direct‑fit replacement intended to maintain proper OEM suspension geometry.
