The Fleece Performance coolant bypass for the 2013-2018 RAM with 6.7L Cummins seamlessly integrates with your truck for an OE fit-and-finish. Features Increased Coolant Flow, Decreased Coolant Temperatures The rear cylinders on the 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 aFleece Coolant Bypass? One of the biggest issues on the 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. Kit Includes: Rear coolant bypass thermostat housing Front coolant bypass thermostat housing New EGR cross-over tube gaskets Black braided nylon coolant bypass hose with protective high temperature sleeve and AN fittings Mounting hardware

Great quality case, keyboard doesn’t work as intended
Color: Dark Cherry
Case is fine and good quality but the keyboard doesn’t work as intended. Bluetooth connects great but the keyboard is formatted incorrectly. For example, when I try to use a dash, it puts an apostrophe instead. I have no idea how to reformat it myself. I’d love just a replacement keyboard

Great buy! Worth the money and the color is nice. The keyboard works, some buttons I haven’t figured out but for the most part it’s worth the purchase!

Great quality case and keyboard
Color: Purple, Color: Purple
Super good quality case, I was actually surprised since it’s such a good price. It fit my 10.9 inch perfectly! Keyboard has magnetic attachment to the case which is super handy, and it connected with Bluetooth seamlessly. Keyboard isn’t silent, it’s on the louder side, but not too loud at all and it doesn’t bother me at all because I prefer clickier keyboards. Oh also something that’s really cool is that you can change the colors of the keyboard, love that!
