• Built to withstand 400lbs max open spring pressure
• Oversize full-complement caged bearingsdesigned for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction
• Intricately balanced lightweight arms ensuring vital valvetrain stability - focusing attentionon 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 excesstop-end heat
• Proven bolt-on shaft mount design that mounts both inlet/exhaustto common shaft, effectively increasing footprint and clampload twofold without any further cylinder head modification
• Chrome moly steel hardened and groundroller 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
