Product Details

This is a Saginaw 800/808 gearbox that is found in many models of Jeeps and some GM small size pick up trucks (S-10). It came in multiple variations. When ordering you will need to know the following information:

3 or 4 Bolt Mounting Pattern

It is most commonly a 3 Bolt “L” mounting pattern, but some models of vehicles use a 4 Bolt “H” mounting pattern. The 3 bolt version is the same pattern, just missing one hole and will bolt right into place. The 4 bolt housings are becoming very rare, therefore they do cost more. Many customers opt to put a 3 bolt in place of the 4 bolt to save money.

Piston Bore Size

It is available in both a (Small Bore “70mm piston” and a Big Bore “80mm piston” depending on the make, model and year of the vehicle. Many Off-road Vehicles customers opt for the larger piston, especially when increasing tire size, because the larger piston gearbox will have more torque.


We offer this gearbox in three ratios: 12:1, 14:1 and 16:1 Variable Ratio. Typically only full race off road vehicles will use a 12:1 ratio. Customers with daily drivers will usually go with the 14 or 16:1VR.
