When rebuilding your C4/C5 its always important to change out the springs and rollers in the rear sprag.
The rear sprag is a one way clutch that rotates freely in one direction but locks tight in the opposite direction.
Over time the springs fatigue and break causing the sprag to slip which affects transmission operation.
Installation is simple, just remove the original springs and rollers and replace with the new ones in the kit.
Kit includes:
-12 Hardened Steel Rollers
- 12 Accordion Springs
