COMP Cams Alum Rocker Arms CS 1.5 Narro - cca19015-16

The original Ultra-Gold Aluminum Rockers changed the way racing and high performance street engine builders approached valve train design. Now, COMP Cams is revolutionizing valve train performance again with the next generation of Ultra-Gold ARC Series Aluminum Rocker Arms, featuring an Arced, Recessed, Contoured design. Using cutting-edge design techniques and manufacturing processes, Ultra-Gold ARC Rockers increase engine power, enhance valve train stability and improve oiling. Ultra-Gold ARC Rockers feature a new extrusion based on improvements developed through FEA analysis, resulting in an even stronger, stiffer body without compromising mass. A new arced channel and contoured top, similar to a bridge design, give the rockers the best strength-to-weight ratio possible. The body has additional CNC contouring to improve clearances for valve covers and springs. Manufactured entirely in the U.S.A., all Ultra-Gold ARC Series Aluminum Rocker Arms feature a spring oiler channel through the body for improved lubrication. Trunnion retaining clips have been replaced with an ultra durable spiral lock type clip, similar to what holds a piston pin in place. Stress relieving radii have also been added to areas of the body, trunnion and pushrod seat insert. Even the included locking nuts (not used in LS applications) have been revised to increase surface area to better maintain lash and eliminate wear. * Increase engine power, enhance valve train stability and improve oiling * CNC-machined, lightweight design removes weight and yields unrivaled quality and ratio accuracy * Arced channel & contoured top give the rockers the best strength to weight ratio possible * Precision-sorted trunnion bearings withstand valve spring pressure up to 700 lbs. * Designed for high performance street and race engines PartNumber : cca19015-16 Description : Ultra Gold Narrow Body Aluminum Roller Rocker Arm; 16 Pieces Title : 19015-16 Alum Rocker Arms, CS 1.5 Narrow ARC S/A Ratio : 1.52 Stud Diameter : 3/8" California Proposition 65 : WARNING: Cancer and Reproductive Harm P65Warnings.ca.gov Engine Family : Chevrolet 262-400 c.i. 8 Cylinder (1988+) w/ Self-Aligning Rockers Maximum Valve Spring Open Pressure : 700 Rocker Arm Material : Aluminum Rocker Arm Ratio : 1.5 Rocker Arm Series : Ultra-Gold ARC Aluminum Rocker Stud Diameter : 3/8 1992-1993 Chevrolet K2500 Cheyenne V8.-cc Engine Components::Rocker Arms 1992 Chevrolet K2500 Scottsdale V8.-cc Engine Components::Rocker Arms 1992-1993 Chevrolet K2500 Silverado V8.-cc Engine Components::Rocker Arms 1988 Chevrolet R20 Custom Deluxe V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Magnavan V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Rally V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Rally Camper Special V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Rally STX V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Vandura V8.-cc Engine Components::Rocker Arms 1989-1994 GMC G3500 Vandura Special V8.-cc Engine Components::Rocker Arms 1988-1993 GMC K1500 Sierra V8.-cc Engine Components::Rocker Arms 1994-1995 GMC K1500 Sierra SL V8.-cc Engine Components::Rocker Arms 1988-1995 GMC K1500 Sierra SLE V8.-cc Engine Components::Rocker Arms 1995 GMC K1500 Sierra SLS V8.-cc Engine Components::Rocker Arms 1994-1995 GMC K1500 Sierra SLT V8.-cc Engine Components::Rocker Arms 1988-1993 GMC K1500 Sierra SLX V8.-cc Engine Components::Rocker Arms 1994-1995 GMC K1500 Sierra Special V8.-cc Engine Components::Rocker Arms 1993 GMC K1500 Sierra Sport V8.-cc Engine Components::Rocker Arms 1988-1993 GMC K2500 Sierra V8.-cc Engine Components::Rocker Arms 1994-1995 GMC K2500 Sierra SL V8.-cc Engine Components::Rocker Arms 1988-1995 GMC K2500 Sierra SLE V8.-cc Engine Components::Rocker Arms 1994-1995 GMC K2500 Sierra SLT V8.-cc Engine Components::Rocker Arms 1988-1993 GMC K2500 Sierra SLX V8.-cc Engine Components::Rocker Arms
