ARP 12-Point Harmonic Balancer Bolt Kit for all 289, 302 and 351 Windsor Engines.

Operating an engine without a functioning harmonic dampener is like taking punches from a pro boxer that isn’t wearing gloves. Just like a boxing glove, the harmonic dampener absorbs an unbelievable amount of kinetic energy in your 289, 302 or 351 Windsor engine as the crankshaft flexes and twists. To make sure your harmonic dampener is locked in position, this ARP 150-2501 12-Point Harmonic Balancer Bolt Kit is designed to exhibit massive clamping force.

Constructed of 8740 chromoly steel for durability and strength, this harmonic balancer bolt kit is finished off with a black oxide coat. The exertion of maximum clamping force is achieved by using 190,000 PSI rated bolts. This kit is finished off with a 1/4” thick, wide area washer and am extra tall 12-point head that accepts a deep socket and eliminates any potential stripping.

Your engine is held together by a myriad of nuts, bolts and screws, which allow it to work despite the incredible pressures and forces acting upon it. However, what happens if that hardware fails, or you need to upgrade it to handle additional performance? With the hardware from ARP, you're getting the best products on the market, and those trusted by Formula 1, IndyCar, NHRA and NASCAR.

Please Note: While following the manufacturers recommended torque sequence, tighten the nuts to the ARP recommended torque specifications using ARP Ultra-Torque Fastener Assembly Lubricant.

Tech Tip: ARP recommends using the ARP Ultra-Torque Fastener Assembly Lubricant as opposed to motor oil or other low quality lubricants. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when insufficient lubricants are used.
