Overview

This Mishimoto silicone hose kit is a direct-fit upgrade for 2011-2016 Chevrolet/GMC applications covering Express 2500, Express 3500, Sierra 2500 HD, Sierra 3500 HD, Silverado 2500 HD. It replaces the weak points of the stock part with stronger materials and better flow or cooling so heat, boost and abuse stay under control on street and track duty. AutoTalent lists verified US-market fitment in the table below.

Why upgrade

Upgrade your Duramax cooling system with the Mishimoto 2011-2016 Chevrolet/GMC 6.6L Duramax LML Silicone Coolant Hose Kit for the perfect combination of performance and durability. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
