Volkswagen 1.8L Turbo 20V M10 ARP Head Stud Kit Painted Aluminum

Description

Product Overview

The ARP Volkswagen 1.8L Turbo 20V M10 head stud kit is a purpose‑built fastening solution engineered for the high‑performance demands of the VW 1.8L turbo engine family. Each kit contains a single M10 size hex bolt crafted from lightweight yet exceptionally strong aluminum, finished with a durable paint coating that resists corrosion and wear. The bolt features a round head design that distributes load evenly across the cylinder head, reducing the risk of stress fractures during extreme combustion pressures. With a thread class of 1A and a right‑hand thread style, installation is straightforward for both seasoned technicians and enthusiastic DIYers. The kit complies with ARP’s Grade 8740 specification, a benchmark for high‑strength automotive fasteners, ensuring that the bolt can handle the torque and thermal cycles typical of performance tuning, racing, and daily driving alike.
