Product Description

Yella Terra hydraulic bolt on pedestal mount roller rocker set, to suit the Buick Series 2 Ecotec V6/L67 3800 .

These rockers feature 5/16" bolts with a rocker arm ratio of 1.95:1/1.9:1 (split ratio)

 

Pro Street roller rockers:

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.

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 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. 

Ideal for harsh street and strip applications, these rockers have got what it takes to last!

 

Why Choose Pro Street?

 

  • 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.
