ATI Crankshaft Steel Dowel Pin for GM LS & Small Block Chevy Engines
The ATI is a precision-machined steel dowel pin designed to properly align and secure ATI Super Dampers on GM LS-series and traditional Small Block Chevy engines.
Measuring 3/16" in diameter by 1/2" long, this dowel pin ensures the damper hub is perfectly centered on the crankshaft, preventing slippage and maintaining proper balance at high RPM.
It is an essential component when installing an ATI Super Damper on LS1, LS6, 5.3L, 6.0L, and classic SBC engines. Manufactured from high-strength steel, this small but critical part helps protect your rotating assembly during street, strip, or track use.
Key Features

- High-Strength Steel Construction – Resists shear forces and deformation under extreme engine loads
- Prevents Damper Shift – Locks the damper hub in place to maintain balance and prevent power loss
- Lightweight Design – Only 0.05 lbs to minimize added rotational mass
- Direct Replacement – Matches OEM dowel specifications for GM LS and Small Block Chevy engines
- USA Made – Precision machined by ATI Performance Products
