When you've got a Cummins B3.9, B5.9, C8.3, ISB 5.9, QSB 6.7, ISC 8.3, ISL, QSL 9 engine that needs an overhaul, there's a genuine advantage to using a Cummins MidRange Overhaul Kit.

Cummins MidRange overhaul kits include all the mandatory parts needed to perform a basic overhaul. Comprised of piston rings, pistons, bearings, gaskets and cylinder liners (if applicable); these kits are priced 10% lower than purchasing the same parts individually. By only including the mandatory parts for an overhaul these kits allow customers and their service providers to determine what additional components will be replaced or reused.  

Every component is engineered with the latest improvements, built and tested to meet rigid Cummins quality standards. Plus, they come with full warranty coverage for up to one year, 100,000 miles or 3,600 hours of operation or specified maintenance interval, whichever occurs first, after the date of installation.
