These are the custom built, Camburg spec. FOX 2.5 coilovers used in our race series long-travel kits for the newer Tacoma, 4-Runner and FJ. The dimensions of these shocks are designed to get maximum wheel travel both on compression and on droop with our kit and are valved for a mix between on and off-road use. These have FOX’s DSC compression adjusters on the remote res. which allows you to make fine tune adjustments (softer/firmer) based on how you’re driving and using your vehicle. These are not off the shelf universal shocks. We also include Eibach 16? x 600# coil springs. Made in the USA.
