HOLDEN 6 PRO SERIES 1pc MAIN STUD GIRDLE suit 179 186 blocks with 3.25" bolt spacing. This is the block of choice for 235 Stroker Engines. Girdle has "186" etched over the front cap to distinguish this girdle from our stock item.

AUSTRALIAN MADE

Suit all 179 186 Red Blocks (Except 186S). We produced this Girdle for a Nostalgic Drag Car we sponsor that was using a HP block. The cap spread was 3 1/4" (1/4" narrower than 202 blocks).  We have only produced 5 with only 3 remaining. We may never produce them in this configuration again. Consumer demand will be the deciding factor if I stock these in the future.

Don't take the gamble. "Buy it Now"

Machine Ground Spacers Included

NEW PRODUCT Designed and Manufactured in a very limited run by us here in Australia using the latest CNC Cutting Technology from 10mm Mild Steel. This quality product ties your main caps together to greatly reduces Harmful Harmonic Vibrations, Cap Walk & Cap Spread in Turbo, Supercharged, Nitrous and high RPM applications. 

Installation of Main Stud Kit HIGHLY Recommended. An ARP stud kit can be purchased for an additional $250.00

Unlike other girdles available ours INCLUDES Machine Ground Spacers to ensure your SONIC Injection girdle is ready to install when you get it. No need to machine and weeken the crest on the main cap. No need to have custom spacers machined at great expence. As with all our Girdles the design minimises sharp changes of direction and large changes in cross-sectional area to minimise stress fractures and flexing while increasing strength with a market leading 10mm thickness. You can be sure you are buying a quality product. Otherwise we wouldn't be using them in our own engines
