Smile HPA Quick Change Rear Spring Kit

This kit allows the user to change spring rates at home or the track in minutes, without disconnecting the lower control arm and without performing another wheel alignment as long as the ride height remains the same.

This kit not only allows you to change your springs very quickly, it also allows you to adjust the ride height of the vehicle with the springs installed. YES! With the springs installed. No need to remove the springs! Most E82/9X coilover kits on the market today, you must unload the spring tension to adjust the rear ride height, but not ours!

What is in the kit:

HPA Rear Ride Height Adjusters
BMW Sealed Radial Thrust Bearings(used on the top of the main spring)
Swift Main and Helper springs
Swift Thrust Sheets(use at the lower portion of the spring, between the helper and the control arm)
