The Chevrolet Duramax LMM Thermostat Housing Kit from Wehrli is crafted from billet aluminum with a semi-gloss black finish, specifically designed for 2006-2010 models. This kit doesn’t just upgrade the look of your Duramax but also transforms your vehicle's performance by optimizing the heat exchange process.

Engineered for enthusiasts looking to enhance their Duramax, this kit effectively replaces the OEM upper radiator hose and coolant return pipe, shifting the coolant path to a more efficient upwards and forward trajectory from the thermostat. This new configuration improves access to driver-side fuel system components, making room for larger aftermarket turbochargers and boosting engine bay organization. The kit includes a coolant pipe, silicone boots, and t-bolt clamps to ensure a seamless installation.
