"Xtra-Lite" Drum Kit - 6 Clutch, w/ Roller Bearing

The Coan Racing COA‑12829A “Xtra‑Lite” Drum Kit (6‑Clutch) is a precision-engineered clutch drum package designed for GM Powerglide transmissions. Constructed around a billet aluminum support with integrated roller bearing, this compact drum delivers both weight savings and exceptional structural rigidity. A matching billet aluminum reaction flange, featuring 12-point straight-cut splines, ensures precise clutch engagement and seamless torque transfer under heavy load.

Tailored for six-plate clutch configurations, the COA‑12829A is engineered to work with Coan’s high-performance Super Pump assemblies (COA‑12815 or COA‑12818A) and requires no internal modifications for installation. Ideal for builders seeking a high-capacity drum that delivers rapid shift response, rotational efficiency, and race-ready performance, this “Xtra-Lite” kit enhances both street and competition setups by optimizing clutch dynamics and reducing rotating mass in demanding Powerglide systems.
