The single row timing chain is a weak link on a 948 engine. This kit includes a cam and crank dual sprocket pulley to convert from a single row to dual timing chain. Also included is the absolute best dual timing chain we could find to fit the new gears. This is a great solution to reduce the chances of timing chain noise on your 948 engine! There is no tensioner integrated into the A series engines so we recommend this kit if you want hassle free operation down the road.
A smart upgrade for all engine rebuilds!
This kit will also fit 1098 and 1275 engines.
