Coats 308101 28mm Spring for 4-Cone Tire Balancers
If you're keeping one of the classic Coats tire balancers running, this is the spring that holds the system together. The Coats 308101 is the OEM replacement spring for the 4-cone system used in Models 600, 650, 700, 850, 1001, and 1004, covering all units built before March 1992. It delivers the tension and support those balancers need to hold the wheel correctly during a spin cycle, and without it, you're not getting accurate readings out of the machine.
These older Coats balancers were built to last, and there's no reason to retire a machine just because a spring wore out or lost its tension. The 308101 drops right into your existing 4-cone setup, restoring the clamping force the system depends on to seat wheels securely before every spin. Steel construction means it handles the repeated compression and release that comes with a busy wheel service bay without giving out on you again quickly.
If your balancer has been losing grip on the cone stack, seating wheels inconsistently, or producing results you don't fully trust, a worn spring is one of the first things to check. This part is stocked and ships fast, so you're not waiting around while your balancer sits idle. It's a straightforward fix that gets a proven machine back to doing its job.
