Coats 28mm Cone Kit, 3.375" - 5.88" for Light Trucks up to 1 Ton
Standard cones top out before they ever reach the bore diameter on a 3/4-ton or 1-ton truck wheel. That's when you start chasing vibrations that aren't really there, or running wheels that never quite centered right. The Coats 28mm Cone Kit covers bore sizes from 3.375" to 5.88", which is the range you need for modern heavy-duty pickups that standard shop cones simply can't handle.
It seats on 28mm balancer shafts and installs tool-free, so you're not slowing down the line fumbling with adapters. High-strength steel construction keeps it from wearing out of shape after repeated use, which matters when you're spinning heavy truck wheels all day. Cheaper cones flex under load and throw your readings off. This one holds its shape. You get a secure, centered grip through the full spin cycle without any wobble at the bore or slop in the fit.
If your shop regularly sees Super Duty, Silverado HD, or Ram 2500 and 3500 work, this kit removes the gap in your balancer setup. It's a direct add-on for Coats balancers with 28mm shafts, no guesswork on compatibility. Stock it once and it covers the full range of oversized truck bores you'll see in a busy week.
