Have an LLY Duramax and want the EGR cooler removed? Tell us the model year before ordering a kit or booking the truck. An early LLY and a 2006 LLY share an engine code, but there are important hardware differences between them.

Send OCDiesel the VIN from your Silverado or Sierra HD and let us know if the up-pipe or exhaust has already been changed. Our Edmonton team can check which EGR hardware fits and quote the installation for your pickup.
