Product details

Increase clearance, performance and ride quality with a set of JKS JSPECâ„¢ 4" lift dual rate coil springs. Fits Jeep Wrangler TJ and LJ models. Includes a complete set of matching front and rear coil springs for a level 2 lift. Dual rate springs provide smooth comfortable ride on road, and transition to a firmer rate when tire movement increases off-road for increased vehicle control. Another benefit is the longer overall length, which allows the use of longer shocks for more wheel travel. Whether loaded down with gear for a weeklong expedition, running light for some rock-crawling fun or loaded with a few friends for a trip to the beach, JSPECâ„¢ coils provide the ride you want and the performance you need. Shop JKS 4" Lift Coil Spring Set for 97–06 Jeep Wrangler TJ & LJ. Dual-rate springs improve ride comfort on-road while delivering increased control and wheel travel off-road. Coil Spring Box Kit: 1997-2006 Jeep Wrangler TJ - 4" Front and Rear Coil Springs

BEFORE YOU ORDER

A few things to know.

How do I order these parts?

Add your exact parts and delivery details, then continue to payment. Eligible orders show the final parts, shipping and tax total and a PayPal button here after automatic checks. Freight, oversized, custom and uncertain items go to JuiceBuilt for a quote. You are charged only after approving PayPal; supplier orders are submitted separately after verified payment.

Does a part number guarantee vehicle fitment?

No. Product descriptions are supplied by the manufacturer. Check the manufacturer application information for your exact vehicle, engine and supporting modifications. Online checkout requires your exact-part fitment acknowledgment. Contact JuiceBuilt before ordering if you need fitment help.

Is the stock shown reserved for me?

No. Availability is a dated supplier snapshot. Inventory can change, and adding a part to your build does not reserve it. Availability and delivery are checked again before payment. A supplier order is confirmed separately after payment.

What about shipping?

Eligible standard-size parts orders with a parts subtotal of $100 or more receive free standard shipping.

The same $100 minimum applies to all brands, including Aerospace Components.

Oversized and freight items are excluded from free shipping at every subtotal, including carbon doors, hoods, trunks and similar large panels. Their shipping charge is quoted separately before payment.

Shipping for orders below $100 is quoted in your reviewed estimate before payment.

Online checkout is initially available for US delivery addresses. For other countries, contact JuiceBuilt for a manual quote before payment.
