Pioneer Race Balancers
These Pioneer race balancers bring the advantages of bonded rubber to high-revving race and street/race applications where an SFI-approved balancer is required. Each balancer features a precision CNC-machined AUSI 1045 steel center bonded to an equally strong steel inertia ring. The advanced design makes these balancers very lightweight for all-steel products. The steel inertia ring on these models is positively protected against forward and backward movement and has the added assurance of bonded rubber to eliminate spinning. Every Pioneer race balancer features easy-to-read, computer-etched timing marks.
