AMS Balance Shaft Eliminator Kits

The AMS Race Balance Shaft Eliminator Kit is the only no-compromise way of removing the factory balance shafts. Eliminating the balance shaft not only frees up horsepower, it also reduces the chance of belt failures ending up in catastrophic damage to your motor. In AMS' experience, replacing the front balance shaft with a stub shaft will increase the chances of oil pump failures. This is likely caused by eliminating the support provided by the rear bearing journal. A stub shaft allows the oil pump gears to push apart and wear into the aluminum pump. Aluminum that is being worn away will enter the clean oil stream and contaminate the engine bearings. Eventually this can result in the oil pump seizing. The AMS shaft is machined to eliminate the counterweight while leaving the bearing journal in place to keep the factory engineered support for the oil pump gears.

This is the same kit used in every AMS built motor including their record breaking 1100whp drag car and Time Attack car.
