Description ARP MAIN STUD KIT FOR 06A 1.8T & 06F TFSI ENGINES USING GIRDLE KITS ARP is the go-to manufacturer in the automotive industry for engine fasteners. Whether it be OEM replacement parts or custom hardware, their dedication to consistent top notch quality has made them a favourite in the racing world. This is an ARP main stud kit for VW/Audi 06A 1.8T & 06F TFSI 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.
