Fleece Performance 03-07 Manual Transmission Cummins Coolant Bypass Kit w/ SS Braided LineIncreased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5. 9 6. 7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure.

Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 5.9/6.7L Cummins suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the cooling system, especially the rear of the block and blow out freeze plugs externally, or the smaller diameter plugs under the valve cover, leading to a failure. Our coolant bypass kit adds a secondary thermostat, that unlike other brands, works based on temperature instead of excessive pressure. This solves the problem before pressure becomes an issue by ensuring consistent temperatures across all six cylinders. Benefits: Lowers coolant temperature at the rear cylinders Ensures consistent temperatures across all cylinders Prevents damaging coolant pressure build up Complete kit comes with braided hose and AN O-ring fittings to ensure a leak-free installation. Why do I need a Fleece Coolant Bypass? One of the biggest issues on the 5.9/6.7L Cummins is the coolant flow problem to the rear cylinders. This can cause catastrophic failure or blow outs of the freeze plugs in an over-temperature / over-pressure condition. The Fleece Coolant Bypass is one of the most important additions you make to improve the reliability and longevity of the Cummins platform.

Boys’ Formal Tuxedo Suit
I’m very satisfied with the Boys’ Formal Tuxedo Suit! The suit looked exactly like the pictures, the material feels nice, and it fit my boy perfectly. Delivery was on time and the packaging was good. Great quality for the price!

Great value and quality, runs slightly small.
This is a great deal and fit perfectly! My kid is more of a size 10 but I ordered size 12. It's only slightly big in the waist but the pants have elastic adjusters so we were able to make it work. It's great quality! We ordered yellow for a school play but I plan to order other colors because my kid feels like a million bucks in his new suit.

A great option for those looking to save some money!
Color: Black, Size: X-Large, Color: Black, Size: X-Large
Last May I got married in Alaska on a glacier. I wanted a suit/tux that would not only look halfway decent, but one that I could expose to the elements and not feel too bad about ruining. Luckily, nothing was ruined and it ended up looking great! The fit overall was relatively true to size with the jacket being a hair too narrow for shoulders. The material was surprisingly very comfortable and well made. I have a longer torso and the jacket was the perfect length as well. I've never been one to go all out spending a ton of money buying or renting a suit or tuxedo, so this was genuinely a lifesaver at the time. If you're in a pinch and need something nice to wear, or just looking to save some money, you won't be disappointed.

My Husband Gets SOOOO Many Compliments
Color: Royal Blue, Size: X-Small
My husband has a closet full of suits. I try to make sure he has 7 suits available to wear, so when his blue one started looking bad, I started looking for a new one, but with inflation money has been tight lately. I saw the price and the reviews on this one and thought, why not take a chance. Wow! I'm so glad I did. He loves it and he looks great. Every single time he wears it, people are like, where did you get that? That's a nice suit, and these are people who where suits (and their wives who know suits). The next time we need to replace a suit, I'm coming right back. He loves wearing it because he is always very comfortable and so far, it hasn't shown any signs of wear. The material is on the thinner side, but thicker than linen, and keeps its shape nicely. When we first got it, I steamed it, and I haven't needed to iron or steam it since, but he does keep it hing up when he isn't wearing it. Tip: use the size guide. I was very hesitant to buy a size as small as it was saying for my husband, but it was right on point. It is an absolutely perfect fit.
