Fred Swanson's Wrangler sprung Zuk flexing it up on a 23* ramp.
Why Wrangler springs on a Samurai? Because the longer and softer the spring, the more flex and better ride you get. In 1995, Rocky Road (then Summit Off-road), designed and installed the first-ever Wrangler spring conversion system for the Samurai. At that time it was a weldon only setup. Due to the popular demand of the YJ springs, and in the spirit of our original ground-breaking creation, we have now designed the ultimate bolton Wrangler spring conversion system. If you're looking for some excellent bolt-on articulation for your vehicle, this cannot be beat. YJ springs are substantially longer than Samurai springs which provide for a ton more suspension flex than standard length springs. With the JP-Eater® kit, your rear springs are about 6" longer than stock; your new front springs are close to 9" longer than stock!!! The spring rate of YJ springs is also surprisingly plush which means you get a super comfortable ride in SPOA configuration. Our test vehicle pulled a 30" front articulation mark off our RTI ramp, and the rear goes even higher. Unheard of for a leaf spring suspension on such a short wheelbase vehicle!
