Description
The PPE Silicone Upper & Lower Coolant Hose Kit replaces the worn or leaky factory coolant hoses in your 2006-2010 GM 6.6L Duramax LBZ/LMM. Factory coolant hose T fittings are molded hose or made out of plastic and are prone to cracking at junctions, causing coolant loss. Replace your worn or leaky factory coolant hose system with PPE's Performance Silicone Coolant Hose Kit.
Perfect for your stock or highly modified Duramax 6.6L diesel truck. Engineered for performance and durability, featuring 4-ply heat-resistant internal fibers that provide strength against high-pressures and temperatures. PPE's Silicone Coolant Hose Kits incorporate TIG welded, polished 304 stainless steel T-fittings that eliminate any chance of failures at the T junctions. Durable 5 mm thick silicone is twice as thick as the factory hose to ensure long-lasting performance. The quick-connect/disconnect end is made from billet aluminum and 304 stainless steel. Worm-drive clamps with W-style inner liners ensure a tight fit that performs better than factory. The PPE Performance Silicone Coolant Hose Kit is a direct, bolt-on upgrade that requires no cutting or modifications. Perfect factory fit with better-than-factory performance.
Features:
- Direct, Bolt-On Upgrade
- Durable, 5mm Thick Silicone
- Includes Upper & Lower Hoses
- 4-Ply Heat-Resistant Internal Fibers
- Worm-Drive Clamps With W-Style Inner Liners
- TIG Welded, Polished 304 Stainless Steel "T" Couplings

Great product and the orange hoses look good under truck hood!
Ken (Tucson) | June 7th, 2026
The only problem that I had was the positioning of the lower hose billet aluminum connection. It was out of position by about 90°, and I didn’t notice it until everything else was connected. That took a little bit of work trying to get it spun around in that very confined space, but other than that, the install was straightforward, and it’s obviously a great product!

Shipped quickly, no issues, great quality, only thing is to remember to tighten all clamps around the tees before installing so you don't forget and have a coolant leak.
Great Quality

Quality of the are awesome! Installation wasn’t too difficult. The color blue looks pretty good although you can’t really see the bottom hoses.
Great Customer Service

Every business and every person makes mistakes. What is important is not that you make mistakes, but how you react and recover when you do make a mistake. Blair Ericksen at XDP did a great job of getting me the correct parts I needed after the wrong ones were initially sent. She made contact right away after I emailed my problem to XDP, and she got the correct parts sent to me even before the incorrect ones had been returned. I appreciate the good customer service and quick response from Blair. I will write a separate review on the parts once I install them (radiator hoses for a 2006 GMC 2500 HD w/ 6.6L diesel).

Very nice looking hoses I myself went with the red coolant hoses they seem to be made of better thicker material then OEM plus they come with very easy to install clamps way better then the oem hose clamps.
