EMPI 17-2954-0 High-Performance Rocker Shaft Kit (1.1:1 Ratio)
Bring maximum stability and reliability to your air-cooled boxer engine: The EMPI 17-2954-0 Rocker Shaft Kit replaces fragile stock components with an ultra-rugged chromoly assembly while maintaining the factory 1.1:1 rocker ratio.
Eliminate broken wavy washers and worn needle bearings once and for all. This high-performance set by EMPI is engineered specifically for demanding street cars and high-revving race engines. Utilizing heavy-duty solid rocker shafts and forged chromoly rocker arms, it stabilizes your valvetrain and eliminates flex under high RPM loads.
