This is a 1 piece billet design that replaces the stock rear servo piston, cushion spring & snap ring.

Aftermarket performance kits encourage you to fit a spacer that will eliminate the cushion on apply.

Unfortunately you are still left with the rear servo breaking under load. This unit is made up of solid billet aluminum which will not crack and CNC machined for accuracy.

The servo assembly kit includes a extra thick retainer to prevent any cracking as standard retainers are known to do. This kit will suit 67-up.
