YELLA TERRA ROLLER ROCKER SET - TFS/AFR LS3 HEADS - PRO STREET - 1.7 - ADJUSTABLE - YT6737

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 510-303 (4.000"+ Bore) 255cc. EASY FIT Rockers bolt on. Fits standard mountings. No machining required. Shaft mount rockers do not require guide plates. Hydraulic kits are designed specifically for use with hydraulic lifters. Adjustable kits are designed for use with both hydraulic and mechanical (solid) lifters. Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat. Requires YT 5123 - 25mm alloy spacer kit.
