Bert SG-1500 Late Model Ball Spline Transmission, 2nd Generation

This ball-spline edition of the Second Generation late model transmission is built for circle-track competition, running in modified classes such as IMCA, UMP, and USMTS, along with late models and street stocks wherever a track's rulebook permits it. The Second Generation design is credited with cutting rotating weight roughly in half, and this unit weighs 40.9 pounds complete. Where it sits in the lineup Next to this ball-spline edition, the same family also comes in a standard late-model length and a longer, Muncie-length housing, so settle on which length your chassis needs before placing an order. Sanctioning bodies differ on what gearbox styles they allow, so weigh your series' current rulebook against a ball-spline unit before buying one for competition. Common questions Q: Does a shifter come with it? No, the matching shifter, sold under part number 1310, is purchased on its own. Q: Who tends to race with this kind of unit? Circle-track modifieds, late models, and street stocks, specifically in series that permit a ball-spline late-model gearbox under their current rules. Confirm your class rules and overall driveline length before ordering, since the ball-spline, standard, and longer housing are each built around a different chassis setup once a car is assembled. This is sold new rather than rebuilt, so no core transmission needs to go back in exchange.
