The BD-Power 1028040 4" Remote Mount Exhaust Brake provides you with additional safety, comfort, and control of your vehicle. Descending grades can be dangerous and tricky, 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.BDÕs rugged cast-iron exhaust brake housing incorporates their exclusive AlumiBronze bushing and positive sealing piston ring, no blind holes for carbon and rust to form, and miles of leak free retarding. The stainless steel butterfly shaft that has proven to stand up under the harsh, high-heat conditions of the exhaust environment, the offset butterfly valve wonÕt stick, and has been strategically placed in the elbow so that it wonÕt impede exhaust flow when in the open position. The brake valve is actuated by an air cylinder.
How It Works:
Using BDs exclusive Variable butterfly Technology, providing peak retarding power throughout the engines rpm range unlike some models that rely on a hole/orifice within the butterfly to calibrate back-pressure only in the higher engine RPM.
Where It Mounts:
The universal in-line design mounts in the exhaust system between the engine and muffler, DPF, or cat. BDÕs Butterfly is constantly exercising thus reducing the possibility of carbon and rust deposit forming that can cause premature wear and binding which can happen with other brands. Furthermore, no maintenance or lubrication is required providing miles of trouble free service.
Universal Fitment:
Because this brake simply mounts in-line it can be used in a wide variety of applications such as medium duty trucks, motorhomes, diesel pickups and more. Some fabrication may be required for installation.

Super comfortable fabric and launders well.
Special Size: 19" Capri with Pockets, Size: Large, Color: Taupe
Super soft fabric with a nice high waist that does not seem to rolll down when exercising, Yeah!
As always I love a good cell phone pocke. After the comfortable fit I also ordered the Slate Blue version.
BTW, I have had 2 knee replacements so this below the knee length is a perfect solution for my vanity issues!.

Great product and quality!
Special Size: 19" Capri with Pockets, Size: Medium, Color: Slate Grey
I got the matching sports bra for these and I love the set together and honestly really liked the shorter leggings. The quality is incredible and super comfortable. For the amount I spent on this set it was absolutely worth it. The material is definitely thick enough so they are squat proof but they fit a little loose. I think I would size down one size if I bought another color in these. Overall great product!

THESE
Special Size: 19" Capri without Pockets, Size: X-Small, Color: Navy
I love these leggings! Purchased Navy seriously I have had a gazillion brands, styles types, ie. flare, etc. over my legging years of which there are many. These are the best so far. Perfect for ME. I am 112lbs. 5'1" so not 'normal human size' as my kids say. The small is perfect. Hits 'capri' length on my smaller frame a little longer for me so yay for that too. These are super good quality and I am picky about leggings. They are better than Costco WHAT? Yes they are. **NOTE: These do NOT have a phone pocket which I was also looking for. I am over phone pockets for now. These you could dress up for a night out. Buying every color. The price point is low-so were my expectations. But VOILA! These were a super surprise. Happiness is my Amazon delivery human.
