ARP MAIN STUD KIT FOR 06A/O6F ENGINES USING GIRDLE KITS
This is an ARP main stud kit for VW/Audi 06A/06F 1.8T/FSI engines using a girdle kit. This kit can help to eliminate main cap walk and fretting and also protect the threads in your engine block. This is a custom kit assembled in house from high quality ARP components. ARP main studs are made from premium grade 8740 alloy steel which is rated far superior to many “aircraft” quality competitors. The studs are heat treated to 200,000 psi then thread rolled afterward, giving them twenty times better fatigue strength over studs threaded prior to treatment (a common practice with lesser quality studs). This kit features longer length studs to accept a girdle plate. These parts are manufactured in the U.S.A. and are 100% re-usable. Main studs require align honing to be done for installation.
