Upgrade your worn or leaking factory Radiator Coolant Hoses with DmaxStore’s Performance Silicone Coolant Hose Kit, engineered to eliminate common failure points entirely. Stock units can crack over time which leads to leaks, overheating, and potential engine damage.
Designed for both stock and highly modified Duramax 6.6L trucks, DmaxStore’s kit features full one-piece molded silicone units, removing the need for separate T-couplings altogether. This eliminates one of the most common failure points found in other aftermarket kits.
Constructed with 4-ply, heat-resistant internal fibers and 5 mm thick premium silicone, twice as thick as factory, these hoses are built to withstand extreme temperatures and high-pressure cooling demands.
DmaxStore’s Performance Silicone Coolant Hose Kit installs as a true direct bolt-on upgrade with no cutting or modifications required. Expect perfect factory fitment with performance and durability that exceed OEM standards.

- Full 1-piece molded hose assemblies (no T-couplings like other aftermarket options)
- Durable 5 mm thick silicone
- 4-ply heat-resistant internal polyester fibers (up to 392 degrees F)
- CNC Billet Aluminum Quick Connect Fitting
- Direct bolt-on installation
- Constant tension clamps on the 4 main Inlet/outlet locations prevent leaks and maintain a tight seal by self adjusting to temperature changes and vibration.
