Construction & Design
Skyjacker’s Dual Rate LT Coil Springs are crafted from high-quality steel with a progressive variable rate design that adapts to different driving conditions. The two-stage coil spring system starts with a softer flex rate to absorb bumps and allow articulation, then transitions to a firmer ride rate to control compression and maintain vehicle stability. Rear coils are side-specific to accommodate the Wrangler’s suspension geometry, ensuring balanced handling and ride quality.
The included track bars and sway bar end links feature heavy-duty pressed-in OEM-style rubber bushings for durability and noise reduction. The adjustable front track bar allows for precise alignment adjustments, while the reinforced rear track bar mount bracket ensures the axle remains centered under the vehicle, preserving proper suspension geometry throughout the lift range.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
