Coats 8112421 Short Cone, 40mm, 2.650" to 3.025"

A worn or wrong-size cone is one of the easiest ways to throw off a balance before you even spin the wheel. The Coats 8112421 Short Cone fits 40mm shaft balancers and centers in the 2.650 inch to 3.025 inch range, giving you a precise seat on a wide span of SUV and light truck wheels without hunting for a different cone every time the bore size shifts.

Built from high-grade steel, it holds its shape under repeated mounting and demounting, so the fit stays tight instead of wearing loose after a few hundred cycles. If you're running it with an SUV spacer, keep an eye on spring tension to get the most accurate seat. That small step keeps your readings consistent instead of chasing phantom imbalance from a cone that isn't seated right.

For a shop handling a steady mix of SUVs and light trucks, a short cone in this range covers more of your daily work without swapping hardware between jobs.

GSG keeps this cone in stock, so a damaged or worn one doesn't slow your balancing bay down.
