Featuring aircraft grade, extruded aluminum rocker arms that will handle open spring pressures up to 600lbs*, the Pro Street range has been designed for use in high revving street engines and race applications.
The Pro Street rocker arm is supported by the same hardware used in our severe race Platinum series, including including massive ground trunnions that have been machined to accommodate oversize needle roller bearings. The ground finish on our trunnions offers smoother operation, lower friction and better bearing compatibility than the machined finish used with comparable products.
Available in traditional stud mount and “Easy Fit” applications, to suit various stud diameters and a wide variety of ratios.
Mounting Types: Available in Stud Mount and Easy Fit
Maximum Open Spring Pressure: 600lbs*
Lifter Compatibility: Hydraulic Easy Fit kits are designed specifically for use with hydraulic lifters.
Adjustable kits are designed for use with both hydraulic and mechanical (solid) lifters.
* Due to various engine rocker arm designs, some applications may handle more open valve spring pressure than others. For more details, please contact our Tech Department.
