- All K-Series engines except K24Z series.
*Highly recommended to use a new chain with install, you want to avoid reusing an old stretched chain.
The K-Tuned Timing Chain Tensioner was designed in conjunction with an oem parts manufacturer and features an upgraded internal spring to support the use of higher lift cams in modified K engines. We have also built the tensioner with reduced overall travel, which will keep it tight against the chain at all times and won't allow it to back off as much as the stock unit. After reviewing some of the past and present designs, we are even backing up our K-Tuned Chain Tensioners with a no-hassle rebuild warranty. If you see any questionable wear or have any question on the internal condition of the tensioner, simply send it back to K-Tuned for a $60 rebuild. We can even offer this service to racers who do not want to risk possible failure of their high dollar engines to a failed tensioner. This service will allow racers to change the tensioner out at frequent intervals or as needed.
