An absolute must for all swingaxle transaxles. Adding hardened shims between the big spider gear and our new steel thrust plate (not powdered iron like stock) eliminates or reduces unwanted spinning motion that breaks or rotates the stock thrust plate, often popping out the snap ring. Proper shimming stops big gear side movement so it has resistance on it at all times and stays totally engaged in small gears. This reduces breakage and creates a mini posi affect. Originated by Gene Berg in 1961. Made in USA by Gene Berg Enterprises. |
