Fleece Performance 94-98 Dodge 5.9L Cummins 12V Coolant Bypass KitIncreased 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. Kits for MY 2003+ include billet hose brackets. 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. The '03-'07 5.9L automatic transmission version will eliminate the factory transmission fluid heat exchanger. The heat exchanger is not a fluid cooler, it was designed for use in cold climates to warm the transmission fluid with the engine coolant. It is not necessary for use in warm climates or high horsepower applications, nor does it detrimentally affect the trucks performance when removed. All 07-13 6.7 trucks, both automatic and manual equipped transmissions, do not have a transmission fluid heat exchanger.

Lightweight Fabric with a Bit of Stretch
Color: Black, Size: Medium, Color: Black, Size: Medium
I'm a fan of any fabric that has a small percentage of Spandex in the blend -- like these pants. (Along with mostly polyester and viscose.) It's not noticeably stretchy but the comfort is there. The fabric is very light and smooth -- and the stripes make a nice design statement. (They're giving me "gangster" vibes. Ha!) I have a 32" waist and the Medium fits me perfectly (with a little room to spare). I do have to hem the bottoms since I'm on the short side, but they taper nicely down the leg. There's an "adjustable waist" mentioned in the headline description, but I don't see anything resembling an adjustable waist on the pants. Just a hook and button closure. (Maybe I'm missing something?) I'm happy to add these to my wardrobe.

Second Best Bifold I’ve Owned
Color: Black
I’ve gone through a lot of wallets over the years (cheap ones, expensive ones, slim cardholders, you name it), and this Timberland bifold with the attached flip pocket is easily the best all-around wallet I’ve ever carried. The leather is excellent: full-grain, soft right out of the box, and it’s aged beautifully in just a few months with a rich patina that actually looks better with every scratch and scuff. Build quality is top-notch: tight, even stitching, no loose threads, and the edges are finished cleanly. Four months of daily front-pocket carry and it still looks practically new. Layout is perfect for me. Six card slots plus the two slip pockets behind them handle everything I need (10 cards + a few folded bills) without getting bulky. The attached flip ID window is a game-changer; I keep my driver’s license and work badge there and can show either in seconds without opening the wallet. Cash fits easily in the full-length bill compartment. It’s genuinely slim for a traditional leather bifold, sits comfortably in both front and back pockets, and never feels like a brick. The embossed Timberland logo is subtle and classy. At this point I can’t imagine switching to anything else. It’s durable, functional, looks sharp, and was a fraction of the price of some “luxury” wallets that didn’t last half as long. If you want a classic leather bifold that actually delivers, this is it. 100% recommended; already planning to buy another as a backup.

Rugged Timberland Quality—The Best Bifold for "Double ID" Needs
Color: Black (Sportz)
Design & Capacity: I’ve been using this wallet for two weeks, and it’s a powerhouse for organization. The attached flip pocket is a game-changer for me because I have to carry both a driver's license and a work security badge. The two ID windows let me show both without digging through card slots. Genuine Leather: Looks and smells premium; will likely weather nicely with age. The Slimness Factor: Timberland calls this a "slimfold," and while it is thinner than a traditional trifold, the flip-out pocket does add some depth. With 6 cards and 5 bills, it measures about 0.75 inches thick. It fits comfortably in my back pocket, but it might be a bit much for a front-pocket-only user.

Wanting a standard nice wallet. Get this
Color: Black, Color: Black
Your standard wallet. Nothing to complain about. Does what it’s supposed to and I have no complaints. The fit is amazing. Holds at least 17 20 dollar bills and over. Durability is also amazing to say the least. Doesn’t rip at all, with a lot of money in it. Its thickness ties in with how much money you can fit in it, so I won’t go into that category. Overall what you see is what you get. A standard, nice, durable wallet that sticks into your pants.
