Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

These high-strength, nodular-iron street performance balancers from Pioneer offer bonded balancer technology to meet the budget of every performance street engine builder from mild to wild. They also make great heavy-duty standard replacement balancers and are perfect for limited-spec race classes, such as late model stock, that require an OE-style balancer. The bonded dampening rubber in these balancers eliminates spinning and component separation, giving reliable performance in engines using up to 6,500 rpm. All Pioneer street balancers feature easy-to-read, permanently etched timing marks on the outer ring.

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.

All piston engines produce crankshaft torsional vibration. TCI Rattler torsional vibration absorbers counteract those vibrations by using internal rollers that automatically offset the twisting forces and eliminate the root cause of torsional vibration. They are effective for the entire RPM range and extend crankshaft and bearing life while also increasing valvetrain stability. Their design does not utilize viscous fluids and they are lighter than most dampers of the same size and material construction. Rattler vibration absorbers feature steel rollers that fit loosely into a specific number of holes. By using an exact, patented, mathematical relationship, the rollers roll forward during the compression stroke and backward during the power stroke to keep engine speed variation and vibration to a minimum. The rollers are actually centrifugal pendulums that store and release energy back into the crankshaft rather than converting it to heat energy as dampers do. They are not frequency specific, but are based on the number of cylinders or the events per revolution so they are practical for street use, as well as track and drag strip use. Features include: * Standard bolt patterns * Available for internally and externally balanced engines * Etched integral timing marks can't move relative to the crankshaft * Maintains maximum effectiveness at all engine speeds * Virtually no maintenance required * No fluids, elastomers, or friction materials * No pulley or crank trigger shims required * CNC-machined to exact tolerances * SFI 18.1 certified
