Yellaterra Chevrolet V8 Small Block Pro Street 7/16" Rockers, Ratio 1.5 #YT5001

Pro Street

Designed for high revving street/strip applications. No other comparable product can compete with 600lbs* maximum open spring pressure whilst retaining factory size bolt-down hardware.

Built to withstand 600lbs* max open spring pressure

Oversize full-complement caged bearings designed for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction.

Intricately balanced CNC billet arms ensuring vital valvetrain stability - focusing attention on the harmony of the entire engine.

Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.

Various ratios available, catering for every camshaft grind. High ratios allow for additional lift on stock and aftermarket camshafts.

Chrome moly steel hardened and ground roller tips of generous diameter (positively retained by internal circlip) preventing abrasion of valve tips and guides commonly seen with non-roller tip rockers. Allows for smoother, quieter operation. Maintains lash and reduces necessary and tedious engine maintenance.
