C15-20188S - SCAT PRO-STREET FORGED COMPLETE 1.25 RATIO ROCKER ASSEMBLIES - W/ADJUSTING SCREWS & SHIMS - ALL 12-1600CC BEETLE

Description

These Pro-street 707 VW forged complete rocker shaft assemblies made by SCAT are a great upgrade from your worn out stock shafts. The extra lift gained with the 1.25 ratio can increase power as much as 10% on most VW engines. Comes complete with Genuine Scat forged 1.25 rockers and Scat solid billet - bolt-together shafts - Swivel feet adjusting screws with shims & spacers. Great upgrade from ACC-C10-5255. These will bolt right on without any special modifications. You may need to shim between the rocker shafts and the head to gain the correct clearance for the stock push rods. These rockers will change lift at the valve from .365 inch to .415 inch and it is always the installers responsibility to check for all possible clearance and geometry problems before final assembly and starting the engine.

We offer a complete line of 1.25 and 1.4 Hi-ratio rocker arms to suit any application, from a strong street runner to all out racing engines.

Special note: When using any high-ratio rocker arms, stock length push rods will not work. You will need to purchase a set of CUT-TO-LENGTH heavy-duty push rods. The length required for any engine is impossible to know until you test assemble your long block and calculate the length required to achieve the correct rocker geometry based on your engine combination.
