Olds Balancer Bolt Kit

The ARP Olds Balancer Bolt Kit is designed specifically for Oldsmobile engines, providing high-strength fastener solutions at the crankshaft harmonic balancer interface. This kit is particularly beneficial for classic and modified Olds powerplants that experience high RPM loads, especially in boosted or high-compression applications.

Manufactured from 8740 chromoly steel, the ARP fasteners undergo heat treatment and shot peening to enhance clamping force and fatigue resistance, exceeding OEM specifications. The advanced thread geometry and surface treatments help prevent galling and ensure even load distribution, maintaining preload integrity during thermal cycling and high-load events.

Engine builders, restoration shops, and street/strip enthusiasts working on Oldsmobile 350, 403, 455, and related displacement variants will find this kit particularly useful, especially when integrating modern fuel systems or ignition timing advancements into their builds.
