Yella Terra YT6345A Ford Inline 6 X-Flow Platinum 7/16" Rockers +.080" Taller Valves, Ratio 1.73 YT 6345A

Item Description

Pedestal Mount

A truly unique rocker design - no other manufacturer offers such a simple to fit assembly. The pedestal bolts directly to the original mounting holes and positively locks the trunion in precise relationship to the valve stem. Provides an extremely rigid rocker. Available in non-adjustable versions for mechanical and hydraulic camshafts.  

Platinum

Designed for strength, built to race. No other rocker system compares with Yella Terra Platinum race series. Manufactured and assembled in Australia using the highest quality materials and componentry sourced locally and from the USA.

Our wide range of true ratios allows you to achieve high lift without relying solely on your camshaft… a trend many engine builders and racers alike are adopting to relieve the inertia on lifters and pushrods generated by aggressive and often violent ramp rates required to make big lift. 

Proven bolt-on shaft design featuring heavy duty 7/16” and 10mm hardware for stability and durability well beyond the chequered flag.

Why Choose Platinum?

  • Wide body arms for greater strength and resistance to deflection, extruded from aircraft grade aluminium for the highest RPM potential. Built to withstand 900lbs* 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.
