We are proud to offer our billet direct clutch piston kit. This kit is what we use on our 4L80E packages up to 800 Ft Lbs of torque. This kit includes our exclusive billet direct clutch piston, new lip seals, 6 High Energy Frictions and 6 Steel plates. You will use your original direct clutch drum, '91 up captured spring retainer, snap rings and pressure plate. This is setup to use a direct clutch drum with a check ball. This can also be used in 400 transmissions as long as the drum has a check ball and you update the spring retainer.

* The piston can be purchased separately if you prefer to use your own seals, frictions and steels.

* THIS KIT IS DESIGNED FOR AN EXPERIENCED TRANSMISSION BUILDER. WE INCLUDE THE BASIC PARTS, BUT EACH SETUP SHOULD BE SPECIFIC TO THE APPLICATION AND THE TRANSMISSION BUILDER'S PREFERENCE. BOWLER PERFORMANCE WILL NOT SHARE SPECIFIC CLUTCH CLEARANCE DETAILS AS THIS IS PROPRIETARY INFORMATION.

** TO BE USED WITH THE LATE 4L80E FULLY CAGED RETURN SPRING SETUP.

We also offer many other upgrades and basic rebuild items, so please call us for your transmission needs.
