Innovators West Harmonic Balancers

Innovators West harmonic balancers are a great investment for your street or race vehicle. These dampers feature lightweight billet aluminum covers equipped with free-floating wet friction clutch pack assemblies that utilize spring-loaded inertia rings to dampen crankshaft harmonics over a wide rpm range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and Innovators West uses a small amount of fluid inside that acts as a lubricant, as well as dissipates heat to the outer body. Backed by over 25 years of experience, Innovators West has produced high-quality SFI 18.1 certified harmonic balancers employing all American-sourced materials and fasteners. Choose the model designed for your vehicle and engine application. Innovators West harmonic balancers/dampers feature: * Billet 6061 aluminum case for lower reciprocating weight * Fully scribed 360 degree timing marks * Laser-engraved part number and SFI rating on back * Premium steel internal inertia rings * Stress-proof steel crankshaft hub * OEM bolt pattern and pulley register

Engine Works Oil Restrictors

Engine Works offers oil restrictors for a variety of engine applications from the 1950s and up. Machined from aluminum, they fit in most small and big block Chevy blocks (except Bowtie) at the rear of the block. Simply replace the oil galley plugs (tapping may be required). These restrictors are not for use with hydraulic lifters. An oil restrictor installs in the oil passages of the engine block. It limits the flow of oil to certain parts of the engine. Engine oil lubricates and cools vital engine components. In most cases, more oil usually means the engine will run cooler and last longer. However, in some specific RACING applications, more oil can actually reduce the performance of the engine. When roller rockers and solid lifters are installed, the amount of oil required by the valvetrain is reduced greatly. Installing an oil restrictor kit will limit the oil flow, reducing the windage created from excess oil draining past the rotating assembly. This keeps the oil flowing where it is needed most—to the rod and main bearings.
