Product Information
Description, Q&A
Description
Description. RockJock is famous for our coil springs! The John Currie secret recipe is renowned for being the best on-road ride and the most off-road flex, all in one spring!
Some of the secret (but not all!) to our dual rate springs is a soft initial rate that absorbs small bumps and trail chop, to deliver a smooth, comfortable ride, while a firmer secondary rate helps soak up larger impacts and reduce bottoming.
A key differentiator of RockJock spec. dual-rate springs is the positioning of the crossover point between the initial and secondary spring rates so that a portion of the softer initial rate is available and active at ride height before crossing over to the firmer secondary rate deeper into the travel.
Lift height varies per vehicle due to factory variances and amount of added on aftermarket equipment. In Sport & Sahara vehicles you can expect around a 3.5 in. lift, and in Rubicons about 2 in. more lift over the stock Rubicon springs.

Word On The Trail
I have used Extreme Terrain for 5 items so far. Everything has went smoothly and all is advertised. I really like the available videos for many of the items, numerous photo's, great instructions and so forth. I would highly suggest giving them a try. Zero complaints.

I’ve always been into cars of all kinds but I really fell in love with my dad’s Jeep. That Jeep was the first vehicle that I felt free in. There is absolutely nothing on the road that is like it except for another Jeep. I love the family associated with the jeep community and the aftermarket options...
