Cummins ISM & M11 Parts

The Cummins M11 and its electronic successor, the ISM, are 10.8L inline-six workhorses that powered a generation of on-highway trucks, vocational rigs, and buses. JAK'S Diesel stocks aftermarket and own-brand parts for both — cylinder heads, fuel injectors, turbochargers, in-frame and overhaul rebuild kits, and full gasket sets — ready to ship same-day from Colorado, with free freight on orders over $1,000.
