This is a billet aluminum rear Banshee suspension shock spacer
This spacer allows you to compress the factory spring
Provides a better ride, and soaks up bumps much better
A MUST more those with an extended swingarm, and don't want to pay $600 for an aftermarket shock
Also, very nice for the larger riders who tend to bottom out the factory spring.
This will fit any year Yamaha Banshee 1987-2006.
