All About Shocks

JSPEC Series Shocks

IFP design eliminates oil aeration Valved specifically for JSPEC systems. Direct bolt-in replacement.

Fox Performance Series IFP Shocks

The 2.0 Performance Series IFP shock has a predicable ride quality capable of handling the roughest road conditions.

Shock absorbers are an important part of your Jeep’s suspension system.  JKS offers a range of custom-valved shocks to fit your budget and performance needs. JSPEC Series gas shocks feature affordable twin-tube design with custom valving for improved handling and ride quality on and off-road. Ride quality is tuned to work with large diameter all-terrain tires. For more aggressive off-road performance, step up to optional FOX shock absorbers. They feature IFP technology, aluminum bodies, heavy duty shafts and superior monotube valving for a better driving experience regardless of terrain. 

Picking the Right Coil Springs

JKS J-Rated Suspension Systems feature custom wound, progressive rate coil springs.  That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight. 

Use the J-Rating™ Terrain Scale to choose the best lift kit for you and your Jeep. Find the right mix from navigating the on-ROAD jungle of your daily commute, TRAIL-riding off-camber and steep terrains, rock CRAWLing -- with maximum articulation and clearance, or bombing the BAJA desert at speed. JKS engineers a range of suspension systems with the right mix of parts for each environment. The J-Rated™ Terrain Scale to point you towards the right suspension system.

How do you use your Jeep?

Road-rated suspension systems deliver better than stock ride quality and performance. Great daily driven Jeeps that are driven on fire roads and see some trail use. Low maintenance. 

Trail-rated kits are designed for weekend adventurers who love to explore. Available in 2.5" and 3.5" lift configurations, improved geometry yields excellent all-around performance for street, wet/dry, loose, rough, or steep-rutted terrains. 

Prefer to challenge your driving skills? Crawl kits dramatically increase your Jeep’s flex and articulation with the extreme duty components. Prepare to crawl some rocks! Routine maintenance is required. 

Embrace speed and handle the roughest terrains with Baja rated kits. Feel in total control through sand, whoops, and some of the most rugged natural terrains in Baja. Some maintenance required.
