Another must have when modifing your XR6 turbo / 4.0 DOHC engine is our HD race billet timing chain kit.
We partnered up with europe's leading timing chain manufacturer to bring a 80% stronger then factory timing chain.
This is needed when using aftermarket stiffer valve springs or if your are on the hunt for power that these engines are fast becoming known for!

Using a pre-stretched chain featuring rollerised trunnions & extra thick link plates, this is the new standard in ensuring reliability and longevity form your engine in regards to timing and performance.

Our billet kit HD timing kit will fit standard or aftermarket sprockets and have OE style timing links to ensure timing is correct when reinstalling.

Understanding the power these engines can created we have created a heavy duty replacement for the timing chain guide pivot constructed of 4140 chrome moly steel.
(these are notorious for failing on modified engines) 
 

Lastly we redesigned the timing tensioner, a lot of other kits on the market use standard duty tensioners and claim they are HD, or worse purchase from importers and claim heavy duty as their apperance is different! 

We have added additional oiling prioity to ensure no dry or seized tensioners. 

We don't just make products we test them! 
This kit has undergone stenous testing on 400 - 700+ rwkw engines and we are more then happy with the performance and reliability.
