Feuling ARP Internal Rocker Box Mount Kit

Feuling ARP Internal Rocker Box Mount Kit

Reinforces the cylinder heads on M8 engines | ARP quality | USA made

Upgrade your M8 engine with this ARP rocker box mounting kit from Feuling – designed to eliminate one of the most well-known weaknesses in Milwaukee-Eight cylinder heads: rocker arm shaft standoffs.
