MINI R50 | R52 | R53 | Cooper | Cooper S | JCW | Timing Chain Kit NO Gaskets

NOW WITH MODIFIED TENSIONER RAIL

Manufactured exclusively for MAR Motorsport by an OE supplier in a TS16949 accredited facility, this is the only kit that uses the modified tensioner rail with machined side relief outside of OEM MINI.
Rail material is the correct PA66 +GF50 polyamide / glass fibre reinforced material unlike other kits – check rails of others for material marking. Crank and cam gears are correctly heat treated – other kits only heat treat the crank gear.

2 year / 50,000 miles warranty!
