Part #: JK20BLT

Overview

The Skyjacker 2-inch Lift Kit Component Box with Dual Rate Springs is engineered specifically for Jeep Wrangler JK models from 2007 through 2018 equipped with 3.6L or 3.8L V6 engines. This lift kit is designed to enhance your Wrangler’s off-road capability while maintaining a comfortable on-road ride. Featuring a progressive variable rate coil spring system, it offers a unique two-stage dual rate long travel coil that adapts to varying terrain and suspension demands.

Ideal for Jeep enthusiasts seeking improved suspension articulation and ride quality, this kit balances flexibility and control. It ensures your tires maintain contact with the ground during full suspension droop, while also providing firm support under compression for stable handling and improved vehicle dynamics.

Key Features

Skyjacker’s innovative design incorporates advanced spring technology and essential suspension components to deliver a reliable lift solution:

• Progressive variable rate coil springs with two distinct stages: Flex Rate and Ride Rate
• First Flex Rate stage allows comfortable ride quality and maximum suspension articulation
• Second Ride Rate stage engages under compression for enhanced stability and handling
• Front and rear bump stop spacers bolt onto axle bump pads to safely limit suspension travel
• Rear track bar lower axle mount bracket re-centers the rear axle for restored handling characteristics
• High-quality grade mounting hardware included for secure installation
• Designed specifically for Jeep Wrangler JK 3.6L and 3.8L V6 engines
• 2-inch lift height provides improved ground clearance without compromising ride comfort

Construction & Design

Skyjacker’s dual rate coil springs are engineered with precision to provide a progressive spring rate that adapts to different driving conditions. The two-stage coil design features a softer initial flex rate that allows the suspension to articulate fully during off-road use, keeping the tires planted and the springs properly seated. When the suspension compresses beyond this initial stage, the firmer ride rate engages to maintain vehicle stability and control.

All components, including bump stop spacers and the rear track bar bracket, are constructed from durable materials designed to withstand rugged off-road environments. The hardware is high-grade to ensure long-lasting performance and secure fitment, maintaining the integrity of your suspension system.

Installation & Fitment

This lift kit is designed for direct bolt-on installation on 2007–2018 Jeep Wrangler JK models with 3.6L or 3.8L V6 engines. The included hardware and components simplify the installation process, requiring no major modifications. Front and rear bump stop spacers install easily onto existing axle bump pads, while the rear track bar bracket re-centers the axle to preserve the Wrangler’s factory handling characteristics.

Professional installation is recommended to ensure proper alignment and suspension geometry, but experienced enthusiasts with basic mechanical skills can complete the installation with common hand tools.
