TRP’s new camshafts and bushing kits for heavy-duty trailer brakes feature camshaft head and shaft splines induction-hardened for long life and durability, the company says. They also have forged camshaft heads for precision-sizing and strength, and a nationwide 12-month warranty. They’re offered in a variety of sizes for all makes.

Worn camshafts can cause uneven or premature brake wear, TRP notes, which can result in decreased stopping power. Worn camshaft bushings can also ultimately lead to an out-of-service violation. If an inspector finds that a missing or  worn camshaft bushing is causing excessive pushrod travel, worn linings on the bottom shoe, or some other brake defect, the inspector will likely note it and apply the 20% defective-brake rule accordingly.

TRP says its camshaft is manufactured using precisely calibrated computer-controlled equipment to meet the demands of today’s harder working brakes.

TRP retailers include Kenworth and Peterbilt dealerships.
