Now Shipping! Lightweight Maindrive Retainers

January 12, 2018

Hard anodized aluminum maindrive retainers for small flange (4.68 inch diameter) 1964-74 ‘Muncie’ and Auto Gear ‘Syracuse’ four-speed transmissions are now available.  And they offer premium performance at a lower cost and half the weight!

FEATURES/BENEFITS

Original equipment technology. Minimum maindrive retainer durability requirements at General Motors and ford are for more shift cycles than your car will ever see, and both have approved and used hard anodized 356T6 aluminum designs.

Made in America. Engineered, cast and machined in the United States, employing American workers, paying American taxes, and protecting American intellectual property.

Superior installation tolerance.  Aluminum bends where iron breaks, and even the best ‘Z-bar’ clutch release system side-loads the retainer tube.  Our new retainer minimizes the possibility of tube failure at a fraction of the cost or weight of billet steel.

Improved clutching. Hard anodizing places the clutch release sleeve on a very hard and slippery surface; the tube wears less rapidly and clutching is faster with less effort.

Easier Gearbox installation.  Socket head capscrews inside the flange diameter and three angled pilot ribs to guide the transmission into the clutch housing are little things you’ll appreciate under the car.

No fiber gasket.  No dissimilar metals to isolate, no shear load on the gasket due to differential thermal expansion, and no unequal gasket compression to crack retainers, encourage leaks or require post assembly retorque.

Pleasing appearance.  A clean, modern design that needs no protection against rust or staining.
