When it comes to running high horsepower RB engines at high RPM as most of them do it's essential your timing belt components are of extreme high quality.

We have produced a timing belt idler & tensioner fastener kit using only the best ARP custom hardware. If a bolt or stud let's go due to porous material or rust that could cost you an entire engine as well as a turbocharger.

This kit includes the following components:

• ARP Bolt
• ARP Stud
• ARP Washers x2
• ARP Nut

If you require new high quality tensioner & idlers please select them from the drop down menu.

These kits suit any factory twin cam RB engine or any SOHC engine converted to a twin cam head. If you need to convert your SOHC engine to twin cam please see out listing for our conversion kit here
