These sets feature a superior 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). Roller timing chains are far stronger than the factory chain and offer less friction, which adds up to accurate timing and more power. They are virtually immune to stretch, even with the heaviest load valve springs, and most aggressive cam profiles. The adjustable timing allows you to tune your cam timing for your specific combination, if you choose.*
The double row set is designed ONLY for engines with the factory balance shaft gear or the entire balance shaft removed. The balance shaft oil feed hole at the rear of the engine MUST be plugged if you remove the balance shaft. The double roller fit is very tight and a timing chain dampener is usually not needed. You will need to run two front timing cover gaskets, with a thin film of RTV between, to allow clearance for the double chain to run without rubbing the inside cover.
* An experienced professional should only do cam timing changes. Serious engine damage could result if done improperly!
