Whether you’re hauling the family fifth wheel or driving out to the job site, you rely on your Duramax to get where you need to go. The factory Duramax L5P radiator hoses are constructed from a mixture of molded rubber and plastic. As your truck endures thousands of heat cycles, hours of idle time, and countless high-stress miles, those materials will begin to degrade, harden, and potentially develop leaks. That's why Mishimoto has designed this replacement silicone coolant hose kit for your 2017-2019 6.6L L5P Duramax. This kit features hoses constructed from five layers of silicone with heat-resistant embedded fibers and all-aluminum hose junctions. This combination yields far more robust coolant passages, which will provide years of service in the harshest conditions. This kit also includes a full set of stainless-steel clamps and a replacement O-ring for your lower hose quick-disconnect fitting, providing everything you need for a hassle and leak-free installation. The Mishimoto Silicone Coolant Hose Kit is available in Black, Blue, or Red and includes our signature Mishimoto Lifetime Warranty.This Part Fits:

Boy Shorts for comfort, stretch and just enough firmness ( but not too much.)
Color: (3 Pack) Black, Size: X-Large
Finally a perfect boy short in every way! I have ordered and returned so many boy short brands up to now. SHARICCA BoyShorts Panties are comfortable, soft, stretchy and the perfect length for me. I wear an XL and am 5’5”. I just reordered the 6 pack and these will be my go to for underwear! Thank you customers for your reviews which helped me decide to try.

Very comfortable, right length
Size: Large, Color: Black,grey
This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.

Nice briefs, worth the price
Size: Medium, Color: White
Briefs feel nice and I love the feel of cotton. Unfortunately they are missing a slot in the crotch that is usually present in these types of briefs.
Size is matching, soft to the touch.
