Balancer Bolt Kits

Balancer Bolt Kits: The Fastener That Keeps Your Damper Where It Belongs

A balancer bolt clamps the harmonic damper onto the crankshaft snout, and on a hard-run engine that single fastener earns its keep. When the factory bolt stretches or backs off, the damper walks, the timing marks drift, and on a diesel you can lose the front seal and the accessory drive with it. Upgraded balancer bolt kits give you a stronger bolt, and often a washer, so the damper stays torqued and located under load. If you are torquing a new damper on, this is the part you replace at the same time rather than reusing a tired original.

What ThreePiece stocks

We currently show 10 products in this category, from two brands: ARP and ATI. ARP accounts for nine of the sampled items, so the range leans heavily toward diesel and performance bolt kits. Prices run from $47 to $517, and that spread is the current range on what is in stock, not a fixed quote.

The low and middle of the range is bolt-kit territory. The ARP Dodge Cummins 6.7L 24V Balancer Bolt Kit and the ARP Ford 6.4L Diesel Balancer Bolt Kit are typical diesel fitments. The top of the range is the ATI Damper for LS1/LS2 F & V Body, a full aluminum damper rather than just a bolt. Product names in this category cover Ford, Dodge, Nissan and Chrysler applications, with a year range spanning 2007 to 2024.

How to choose

The first question is whether you need a bolt kit or a complete damper. If your damper is sound and you just want a stronger fastener during a build, an ARP kit is the direct answer. If the damper itself is worn or you are chasing rotating-assembly upgrades on an LS, the ATI damper is the bigger, pricier commitment. The second question is fitment: these bolts are engine-specific. Match the kit to your exact engine family, because a Cummins bolt will not carry over to a Ford diesel or a Chrysler application. Only one product carries detailed fitment data here, and it maps to Dodge Cummins, so confirm your engine before you order.

What else you need with it

A damper job rarely stands alone. If you are pulling the front cover, plan for the gasket kits and head gaskets you will disturb. A rotating-assembly refresh usually pulls in bearings and pistons as well. While the front of the engine is open, it is a good time to look at fuel pumps and radiators. Browse the full Engine Components section to see everything in the same family.
