OEM replacement balancers feature the strength and durability of bonded dampening rubber at a price point attractive to all automotive repairers and stock engine builders. Virtually all OEM replacement balancers use press inserted dampening rubber which is prone to spinning and dislocation in high torgue and serpentine belt applications. The bonded dampening rubber in OEM sets the range apart. In push apart and torque tests the OEM design has up to 4 times the strength of inserted balancers. To ensure smooth operation all OEM replacement balancers are dynamically balanced at the factory. With unique combination of high strength castings, bonded dampening rubber and dynamic balance, the OEM range is not only the ultimate standard replacement balancer but also perfect for budget "Claimer Motor" circle track racing.
