New from Proform – the Race Series Shaft-Mounted Buick 455 Roller Rockers. These rockers will help take your Buick to the next level of performance by significantly reducing valve train friction. See more details below.
Horsepower and torque have been a part of Buick’s genetic makeup since the 1960’s, with the venerable 455 as the brand’s flagship power maker. The 455 and other powerful Buick engines helped early racers to victory. PROFORM continues in the tradition of high-performance racing with the all new Race Series Shaft-Mounted Buick 455 Roller Rockers.
Take your Buick valve train to the next level of performance with this friction-reducing roller rocker system. These rockers are made of quality billet aluminum and designed for a 1.65 Ratio. They fit standard stage 1 and 2 cylinder heads (Please note that the push rod hole many require additional clearance).
