Pro Street 428 FE Shaft Rockers - FE Big Block Shaft Rockers

  • 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.
  • 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 circle)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.
