Yella Terra Chevrolet V8 LS3/LS9/LSA/L98 Pro Street 10mm Shaft Mount Rockers, Ratio 1.7 For TFS 255cc or AFR 260cc Heads

YT6653-M10
Yella Terra Pro Street is ideal for high revving street/strip applications. Manufactured and assembled in Australia using the highest quality materials. The Pro Street rocker arm is supported by the same hardware used in our severe race Platinum series, including massive ground trunnions that have been machined to accommodate oversize needle roller bearings. The ground finish on our trunnions offers smoother operation, lower friction and better bearing compatibility than the machined finish used with comparable products. Compatible with Chevy/GMC Series Trucks: L76, L77, LY6, L92, L94, L96, LC8, LC9, LH9, LMF, LH9.

Don't fall victim to bearing/trunnion upgrades which only address half the shortcomings of OEM rockers.

Note: Requires PN: YT5123 25mm alloy spacer, which can be added using the product options.
Pricing: $841.75

Description

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 aluminum, 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.
