Mopar Head Stud Kit - 5.7/6.1L Hemi

The ARP Mopar Head Stud Kit for 5.7/6.1L Hemi engines is designed for builders and enthusiasts who require exceptional reliability under high cylinder pressure and thermal cycling. This kit is essential for anyone looking to enhance the performance of their Hemi engine, whether it’s a stock 5.7L or a modified 6.1L pushing serious horsepower.

Constructed from 8740 chromoly steel and heat-treated to precise specifications, ARP studs replace factory head bolts that can flex and stretch under extreme conditions. The proprietary thread design ensures an even distribution of load, maintaining clamp load consistency across multiple heat cycles. This design helps prevent catastrophic head gasket failure and extends the life of the cylinder head.

Ideal for applications involving forced induction, high compression, or nitrous, this head stud kit is crucial for any 5.7L or 6.1L Hemi experiencing blow-by or repeated gasket failures. Installation requires the engine to be at or near top-dead-center with the head removed, ensuring a precise fit and optimal performance.
