Rusty's Coils - JL 3.75" Rear - HEAVY DUTY (Pair)

Now in stock and shipping! Rusty's new progressive-rate rear coil springs for the JL Wrangler were designed specifically for our overland customers who carry a lot of extra weight. With thousands of hours of R&D behind them, both in computer modeling and real-world testing, these springs are engineered to support heavy loads without sacrificing ride quality or handling.

We know that overland enthusiasts demand a spring that can handle the constant weight of gear, rooftop tents, bumpers, and other accessories. Our new heavy-duty rear springs provide the durability and support you need while maintaining a smooth, comfortable ride on the road and excellent articulation on the trail.

Don't be fooled by one-size-fits-all solutions. Many manufacturers cut corners by adapting springs from other applications, leading to a compromised ride and poor performance under load. Rusty's rear springs were developed specifically for the JL Wrangler, taking into account the vehicle's unique weight distribution and suspension geometry. This is why our springs are the best you can buy, providing a perfect fit and optimum performance for your overland rig.

Sold in pairs and proudly Made in the USA, our heavy-duty rear springs are the ultimate upgrade for your JL Wrangler. Stop compromising and get the springs that were built for your adventure. Our 3.75" coil springs maintain factory ride and handling characteristics while having a heavier spring rate built into them. They will clear 37" tires without any body modifications and provide the durability to tackle any trail in the country. With light modifications (such as aftermarket fenders) these springs provide the room for 40s and even 42s.
