Whats up with the OE weak sauce hydraulic timing chain tensioner? We’ve had to rebuild countless motors due to cam chain slack issues chewing up timing teeth, chain guides, skipping timing gears and the like.
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 and 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.
Made in Minden (Reno) Nevada from Space Shuttle alloys by an aerospace engineer turned moto part designer / manufacturer.
