Rollmaster timing sets are manufactured by Precision Cam Drives of Australia and feature the finest quality high tensile German made seamless roller chain, precision machined single piece billet crank and cam sprockets, and nine position cam timing adjustability via multiple keyways on the crank sprocket  (+/- 8 degrees in 2 degree increments) Double chain sets are required for engines running valve springs higher than 105 pound.

The adjustable timing allows you to tune your cam timing for better peak power, or better low end torque (NOTE: it is recommended to check piston to valve clearances when changing cam timing. Failure to do so may result in serious engine damage).

The single row set is a direct drop in replacement for the factory timing set. Simply remove the factory crank and cam sprockets, with the chain, transfer the cam positioner magnet from the factory cam sprocket to the new roller sprocket, and install the new timing set.

To run the *double roller, the balance shaft gear must be removed. To save additional weight the balance shaft can removed altogether but this requires plugging the rear oiling hole. The Rollmaster has a much tighter fit, so the timing chain tensioner is no longer  used.

*Due to potential front cover clearance issues on some cars, we recommend running 2 front cover gaskets and our machined oil pump cover when installing the double roller.
