Heavy Duty Seats

Transmission » Shifter Parts Heavy Duty Seats

It's common for the factory shift lever ball seat to wear, crumble and disintegrate over time. This often results in a sloppy or loose transmission shifter. The factory seat is soft and is squeezed into position. Therefore it is fragile. We took a different approach. Instead of squeezing the seat into place, we machine a strong, rigid piece that rotates & drops into position. This allows us to make our seat from stronger, longer lasting USA-made Delrin. Our new heavy duty seats will far out last the stock units and will greatly reduce shifter slop.

If your transmission is not listed, don't despair! While we cannot guarantee if our seats will fit other applications, they have been found to fit other applications based on the bore diameter of your transmission's shifter base: Our Blue seats are designed for a 39mm bore, our Red seats are designed for a 41mm bore, and our White seats are designed for a 42mm bore. If you order a seat and find it doesn't fit, you will be subject to our restocking fee if returned.

It is highly recommended to use our HD seats in conjunction with our HD Shifter Sockets for maximum performance.
