Designed for sideways mount carbs. Each kit utilizes stainless steel shafts that have ground and rolled 36 spline ends to match the anodized aluminum serrated ends. Each moving part rides in needle bearings or spherical rod ends. All mounting brackets are anodized billet aluminum and the kit features right and left hand thread turnbuckles. Kits fit most popular tunnel rams, including Edelbrock, Offy and Weiand.
