BLOX Racing subframe hard collar kits improve handling, responsiveness, and make your vehicle safer on and off the track. They are easy to install and provide immediate improvements to the chassis.
Installing the hard collar kit will help eliminate any play between the chassis and subframe, thus increasing vehicle stability and suspension precision. Our hard collars fill the 2mm gap around the bolts to provide a tighter fit whereby preventing the subframe from moving.
