Description
Aeroflow Heavy Duty SBC Harmonic Balancer Bolt & Washer Kit
Engineered specifically for Small Block Chevy V8 engines, providing high-tensile damper retention and an integrated 1/2″ drive socket for effortless engine rotation.
Product Overview
The Aeroflow Performance AF37-0010 Heavy Duty Harmonic Balancer Bolt provides ultimate security for your Small Block Chevrolet engine build. Factory balancer bolts can stretch or loosen under performance conditions and aggressive RPM acceleration, risking severe crankshaft and damper damage. Aeroflow manufactures this bolt from high-tensile strength steel to maintain critical clamping load on the harmonic balancer.
A standout design feature of the AF37-0010 is the integrated 1/2″ square drive socket built directly into the bolt head. This allows engine builders and mechanics to insert a standard 1/2″ drive ratchet or breaker bar directly into the crankshaft snout to manually turn over the assembly during valve adjustment, timing checks, or engine building.
Key Features
- ☑ Integrated 1/2″ Square Drive: Accepts a standard 1/2″ drive breaker bar or ratchet to manually rotate the crank assembly with ease.
- ☑ Thick Flat Hardened Washer: Spreads clamping load evenly over a larger surface area to prevent damper face damage.
- ☑ High Tensile Construction: Heavy-duty high-strength fastener designed to withstand engine vibration and performance harmonics.
- ☑ Engineered for SBC V8: Precision dimensions (2.250″ UHL) formatted for Small Block Chevrolet engines.
