More About Heavy Duty (Class 8 & 9) Diesel Overhaul Kits

What’s the difference between In-Frame & Overhaul Kits?

To begin, the contents of the kits: an in-frame kit has fewer components than an overhaul kit. The in-frame process rebuilds an engine without removing the front cover or crankshaft. Due to this the in-frame kit does not contain those respective gaskets and the engine remains inside the vehicle. These kits are typically designed for preventative maintenance.

The out-of-frame/overhaul kit contains much more since the engine is removed from the frame and disassembled. The rebuild process often requires engine block re-facing to smooth out the surface and cylinder re-boring to adjust clearances within the cylinder holes. An overhaul kit comes complete with the in-frame kit as well as the front and rear crankshaft seals for a complete overhaul gasket kit.
