Shop 24V Cummins Engine Parts by Category

Engine Sealing & Block Components

Freeze plugs, oil pan bolt kits, and block-level sealing components for the 5.9L 24-valve Cummins. XDP's bolt-on side freeze plug kit (XD334) is a direct-fit replacement that eliminates the need to drive out the OEM press-fit plugs - a common source of coolant leaks on high-mileage 24V engines.

Oil System Components

Oil fill caps and piston oil squirters for the 24-valve 5.9L Cummins. Wehrli billet aluminum oil fill caps are a direct replacement for the factory plastic cap. XDP piston oil squirters (XD341) replace the factory squirters that supply oil to the piston undersides for cooling.

Cooling System

Thermostats for the 5.9L/6.7L Cummins. The Mishimoto low-temperature thermostat is a direct replacement that opens at a lower temperature than stock - reduces operating temperatures on modified or high-EGT trucks.

Rotating Assembly

Harmonic balancers for the 5.9L Cummins. The factory rubber-bonded harmonic balancer is a known weak point on high-mileage engines - the rubber bond separates and the outer ring spins independently, causing vibration and accessory belt issues. A quality replacement restores correct crankshaft vibration damping.

For fuel system, turbo, and performance upgrades, see all 24V 5.9 Cummins parts. For the earlier 12V 5.9 Cummins (1989-1998), visit the 12V parts collection.

Frequently Asked Questions

  • The 24-valve 5.9L Cummins ran from 1998.5 through 2002 in Dodge Ram 2500/3500. True 1998 trucks used the 12-valve - for those, see the 12V 5.9 Cummins (1989-1998) parts collection.

  • The 12-valve (1989-1998) uses a mechanical P7100 injection pump; the 24-valve (1998.5-2002) uses a Bosch VP44 electronic pump. The 12-valve is known for extreme durability; the 24-valve is electronically controlled and more refined.

  • XDP (freeze plug kits, piston oil squirters), Wehrli Custom Fabrication (billet oil fill caps), and Mishimoto (low-temperature thermostats).

  • Some parts - thermostats and oil components - are cross-compatible. Check individual product listings for exact fitment years before ordering.
