CHEVV8 LS7 1.8 HYD SHAFT MOUNT PLATINUM ROLLER ROCKERS - SUITABLE FOR TRICKFLOW AND GM CYCLINDER HEADS
Ultralite
Less weight over the nose.
Designed for high revving street/strip applications. No other comparable product can compete with 480 lbs* maximum open spring pressure whilst retaining factory size bolt-down hardware.
Manufactured and assembled in Australia using the highest quality materials and componentry consistent with those found in our Platinum race series.
Our wide range of true ratios allows you to achieve high lift.
Why Choose Ultralite?
Built to withstand 480 lbs * 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 lightweight arms ensuring vital valvetrain stability - focusing attention on the harmony of the entire engine. 50% less oscillating nose weight eliminates valve float in upper RPM range allowing for higher rev ceiling.
Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.
Proven bolt-on shaft mount design that mounts both inlet/exhaust to common shaft, effectively increasing footprint and clamp load twofold without any further cylinder head modification.
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.
