RCM – STI Timing Belt Kit & RCM Alloy Camshaft Pulley Upgrade Kit 99-02MY EJ20/22/25

RCM prides itself having OE parts manufacturers as their technical partners. This is never more important than with our range of RCM Power Parts timing belt kits where we are working closely with NTN, NSK, Koyo & Aisin to formulate our range.
Sourcing direct with the manufacturers enables us to offer the same high quality OE componentry as used by vehicle manufacturers, giving you complete peace of mind but at a fraction of the original cost.
Whether your running standard, lightly or heavily modified power levels, our ethos with all our Power Parts range is a no compromise approach to using the very best quality components.
This particular timing belt kit uses exactly the same components as when your car rolled off the production line but also includes the high performance Kevlar Timing Belt from the STI Sports Parts range. Specifically designed to withstand the stress and heat found in high horsepower or high revving engines.
One weak area on the Subaru EJ series engines is Subaru’s use of the plastic Bakalite camshaft drive pulleys. Over time, these become brittle and eventually fail causing catastrophic failure and internal engine damage. Included in this kit are the RCM alloy camshaft pulleys which are manufactuRed in aluminium giving you total peace of mind.
For more extreme power levels and applications, we also offer a Motorsport Tensioner upgrade for this kit featuring increased load actuation.
