Is your LLY 6.6 Duramax engine in need of a refreshing? We have engine rebuild kits that will restore your engine to brand new. Our kits include high quality pistons, bearings, seals, and gaskets from leading manufacturers.
There are two different types of rebuild kits. The first is a "rering" kit. This kit would reuse the pistons you already have. It includes new piston rings to restore the seal in the cylinders. They also come with new bearings, gaskets, and seals to refresh the rest of the engine. These kits are used when an engine needs refreshed and the cylinders are in good shape not requiring boring.
If the cylinders have too much wear, they will need bored and you will need a full rebuild kit that includes new pistons. Your machine shop will measure the bore and tell you how much they need to bore the cylinders to remove the wear or damage. The standard sizes to bore the cylinder out are .20 or .40 over stock. Oversize pistons are the same price as stock usually.
If you have any questions about what engine kit you may need or if you have any special requests for components not normally included in the kit, please give us a call.
