Description
If you’re running a Bert transmission, proper tailshaft retention is non-negotiable—this stopper washer ensures your ball spline assembly stays secure under extreme load and shock. A single point of failure in your drivetrain can cost you a race or worse, so OEM-quality components like this one are essential maintenance pieces. Install this washer during tailshaft assembly or rebuild to maintain the precise tolerance and durability your transmission demands.
