What’s the big deal about harmonic balancer bolts? As the revs of your high-performance engine rise, your crankshaft starts to flex. The harmonic balancer press fit to the end absorbs those vibrations, protecting your main bearings and crankshaft bearings while keeping your engine running smoothly. On most engines, a single bolt locks the harmonic balancer in place, so you better make sure it’s a good one—get it from Summit Racing Equipment!
Many stock harmonic balancer bolts are torque-to-yield (TTY) bolts, which means they shouldn’t be reused. So, whether you’re replacing a stock balancer, or upgrading...
What’s the big deal about harmonic balancer bolts? As the revs of your high-performance engine rise, your crankshaft starts to flex. The harmonic balancer press fit to the end absorbs those vibrations, protecting your main bearings and crankshaft bearings while keeping your engine running smoothly. On most engines, a single bolt locks the harmonic balancer in place, so you better make sure it’s a good one—get it from Summit Racing Equipment!
Many stock harmonic balancer bolts are torque-to-yield (TTY) bolts, which means they shouldn’t be reused. So, whether you’re replacing a stock balancer, or upgrading to a durable race-ready model, you should get new hardware for it as well. Most of the bolts we carry are reusable, so your next service or upgrade projects will be even easier!
Summit’s powerful search tools make it simple to find the right harmonic balancer bolt for your application. You can search by Make/Engine to find a stock replacement, or by dimensions, thread count, or tensile strength rating for your aftermarket crank.
