Descending grades with trailers can be hazardous and tricky situations, resulting in over heated service and trailer brakes, that leads to brake fade, excessive wear, and costly unwarranted repairs. BD Engine brake has been the industries time proven VARIABLE REGULATING BACK-PRESSURE EXHAUST BRAKE.Controlled by a lighted On/Off toggle switch or optional stick-mounted rocker switch for manual transmissions, the BD brake communicates with the engines electronic idle verification board for quick engagement. Where it mounts: Most vehicle applications will either have BDs turbo-mount design which bolts in place of the factory elbow between the turbo and the exhaust system or the inline design mounts in the exhaust system between the engine and muffler/DPF/cat. The BD Brakes rugged cast-iron housing incorporates BDs exclusive AlumiBronze bushing and positive sealing piston ring, no blind holes for carbon and rust to form, and miles of leak free retarding. Brake valve is actuated by an air cylinder (newer models) or a powerful, three- in. vacuum cylinder (earlier models). The durable air compressor included in later model kits can even be used for other applications, such as air horns, air bags even air-ride fifth wheel hitches –it is that tough. Automatic-equipped trucks prior to 2006 require BDs programmable AutoLoc and PressureLoc kits to electronically control torque converter clutch engagement. This addition effectively reduces slippage, resulting in peak retarding performance as well as lower transmission temperatures. All BD Brake kits come complete with the brake, air compressor (where applicable), mounting hardware, port to monitor the brakes retarding performance, complete instructions and most models come with EGT port.This Part Fits:

Absolutely Essential for Any Athlete or Gym-Goer!
Size: Large, Color: (035) Steel / White / Black
I recently purchased the Under Armour Unisex-Adult Training Cotton No Show Socks 6 Pack, and I must say, they've become an indispensable part of my workout gear. Here's why these socks are a game-changer:
Comfort Above All: These socks are incredibly comfortable. Made from a blend of cotton and synthetic fibers, they provide just the right amount of cushioning without feeling bulky. Whether I'm running, lifting weights, or doing yoga, my feet feel supported yet free.
No Show, All Go: True to their name, these socks stay perfectly in place without slipping down into my shoes. This is crucial for maintaining a professional look at the gym or during sports activities. No more embarrassing sock peeks or having to constantly adjust them.
Durability: For the price, these socks hold up remarkably well. I've washed them multiple times, and they haven't lost their shape or elasticity. They've survived the rigors of both my workouts and laundry day.
Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions.
Pack Value: Getting six pairs in one go is fantastic. It means I always have a fresh pair ready, which is perfect for someone like me who works out frequently.
Fit for All: These socks fit true to size and are designed to be unisex, making them a versatile choice for anyone looking to upgrade their sock game.
If you're in the market for socks that combine comfort, performance, and style, look no further. Under Armour has nailed it with these no-show socks. They've quickly become a staple in my wardrobe, and I find myself reaching for them over any other sock I own. Highly recommended for anyone serious about their fitness routine or just wanting reliable, high-quality socks.

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too.
Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.
