Dirt Tricks TC-3 Cam Chain Tensioner for KTM and Husqvarna 4-Stroke Engines

The Dirt Tricks Timing Chain Tensioner resolves issues with a slack timing chain on the new 4-stroke motors. The 2008 and newer four-strokes use a timing chain tensioning device intended to develop its force using the engine oil pressure hydraulically. The OEM components have serious flaws, which can leave the timing chain in a slack condition. This can have disastrous consequences. The Founder of Dirt Tricks developed our timing chain tensioner as a simple, effective, and fail-safe replacement for the OEM tensioner. It correctly captures the oil pressure and uses a positive mechanical ratcheting system to prevent it from collapsing. If you have a “ticking” noise at idle, on your newer 4-stroke, you need this part.

The Dirt Tricks TC-3 Cam Chain Tensioner is a durable replacement for the original-equipment hydraulic timing chain tensioner used on select modern 4-stroke motorcycles. Designed to address timing chain slack and idle ticking, this tensioner captures engine oil pressure while adding a positive mechanical ratcheting system that helps prevent the tensioner from collapsing. The result is more consistent cam chain control and dependable operation under changing engine conditions.

The TC-3 is engineered as a simple, effective, and fail-safe upgrade for riders who want improved confidence in the cam timing system. Its mechanical locking design helps maintain proper tension even when hydraulic pressure fluctuates, reducing the risk associated with a slack timing chain. This Dirt Tricks cam chain tensioner is intended for compatible KTM and Husqvarna applications and should be installed according to the motorcycle manufacturer’s service procedures.
