Description, Q&A
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.
_x005F_x000D_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 (LBZ, LMM, LML) end is made from billet aluminum and 304 stainless steel. Stainless steel clamps ensure a tight fit that performs better than factory.
_x005F_x000D_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.

Review shared from PPE Intercooler Coolant Heat Exchanger (20-25 3.0L Duramax Silverado 1500)
Replaced Factory Intercooler
A chunk of ice damaged my factory heat exchanger and the PPE Intercooler was about the same price as the factory incooler. It fit good and was an easy install. Next install will a PPE intercooler. I’d buy again!

2021 3.0 duramax
Bought the PPE resonator delete and the Intake and Intercooler hose kit to fix no restart issue, problem solved. After 2 tanks of fuel I am still seeing a increase of 1.7 mpg.

Definitely worth it
I installed these on my 2024 Silverado and the difference from stock is night and day. These are much thicker and more heavy duty then the stock ones. My frien who is a GM mechanic recommended these because he’s seen the stock ones just blow apart.
