Titan - Spring Pre-Load Cartridge   

CNC machined aluminum spring cage allows you to pre-load a 3” x 10” coil overspring independently of the shock. This allows for quick and easy shock and spring changes. Used commonly with softer springs from 100# to 200#. If you take the Free height of a 150# spring and add 1 inch of pre-load, you now have a spring that has 300 lbs of preload. As the car transfers the pro-load lightens and the spring acts like its much lighter. In turn giving more forward traction.  • Fits 10" & 12" x 3" Diameter Springs • Enlarged I.D. to fit most Shock Bodies • Has an Incorporated Rubber O-Ring as a travel indicator • Machined out to allow the release of heat around the shock • Extra depth on the top of the body to fit all brands of shock nuts • Made in the USA • Fits AFCO, JRI, Ohlins, Penske, Pro and others.  **** Does not fit QA1 6200 Series *** *
