PacBrake PRXB Inline Exhaust Brake 07.5-18 Dodge Ram 6.7L CumminsThe PRXB exhaust brake from PacBrake provides stopping power to not only save your service brakes, but keep you and your load safe on nasty descents. This kit mounts inline (as opposed to turbo mount) to an aftermarket 4 exhaust. For those that had a 5. 9L Cummins with a PacBrake exhaust brake, and then made the switch to a 6. 7L with a factory VGT brake, you know all too well that the PacBrake completely outperformed the slowing power of the factory

The PRXB exhaust brake from PacBrake provides stopping power to not only save your service brakes, but keep you and your load safe on nasty descents. This kit mounts inline (as opposed to turbo mount) to an aftermarket 4 exhaust.

For those that had a 5.9L Cummins with a PacBrake exhaust brake, and then made the switch to a 6.7L with a factory VGT brake, you know all too well that the PacBrake completely outperformed the slowing power of the factory unit. Sure, the VGT works good for a factory unit, but it truly doesn't compare to a traditional, butterfly valve style of brake, such as the PRXB.

And for those that have upgraded turbo to a non-VGT style of turbo, such as an S300, you've now completely eliminated any exhaust brake. If you're ready to get a brake back, and have something that's performance completely overshadows that of the stock exhaust brake, you need to upgrade with this replacement from PacBrake.

VEHICLE REQUIREMENTS:
  • 4" or 5" Turbo Back Exhaust
  • Non-VGT (Variable Geometry Turbo)

WHAT IS A PRXB? A PRXB is a Pressure Regulated Exhaust Brake that offers the highest retarding power for the lowest price available. Although the PRXB's retarding power is comparable to that of a compression release engine brake, the manufacturing and installation costs are significantly less.

HOW IS IT DIFFERENT FROM A STANDARD FIXED ORIFICE EXHAUST BRAKE? Conventional exhaust brakes experience a reduced exhaust backpressure at low engine speeds, resulting in an unnecessary loss of braking power. Pacbrake's innovative PRXB addresses this issue with a patented wastegate design that regulates exhaust backpressure as engine speed changes. The valve maintains near constant engine backpressure throughout the entire RPM range, providing maximum exhaust braking power at all times.

Controlled by a master ON/OFF switch, Pacbrake's exhaust brakes provide whisper quiet supplemental braking that allows service brakes to be used much less, ultimately saving money. They have the ability to be left on all the time, making it ideal for in-city driving or for steep, downhill grades. This product pays for itself as less wear on the brake pads means fewer brake jobs.

The smell is wonderful
Size: 16 Fl Oz (Pack of 1)
This product smells really nice. Like clean fresh leather. My seats look nice. My dog had an accident all over the front of my seat and after cleaning thoroughly, this seemed to really help.

Chemical Guys Leather Quick Detailer for Car Interiors 32oz
Size: 32 Fl Oz (Pack of 1)
Reliable Quick Cleaner for Leather Interiors I’ve been using the Chemical Guys Leather Quick Detailer on my car’s interior for a while now, and it’s become one of those go-to products I like to keep on hand. As the name suggests, this is designed for quick touch-ups rather than deep cleaning, and for that purpose, it really does the job well. The first thing I noticed is how easy it is to use. A couple of sprays on the leather seats or steering wheel, a quick wipe with a microfiber cloth, and the surface instantly looks cleaner. It removes light dust, dirt, and fingerprints in seconds. Unlike some products I’ve tried in the past, it doesn’t leave behind a slick or greasy feel, which is important when you’re dealing with things like a steering wheel or gear shifter that you’re constantly touching. Instead, the finish is clean, soft, and natural-looking, which is exactly what I want. The scent is another plus. It has a pleasant, subtle leather fragrance that makes the car smell fresh without being overwhelming or chemical-like. I don’t like products that leave behind a strong odor, and this one strikes the right balance. Another strength is its versatility. While it’s marketed as a car interior detailer, I’ve found it works well on other small leather items, like a laptop bag or even a chair at home. Obviously, it’s not a replacement for a full leather conditioner, but for light upkeep it’s nice to have a single product that can handle more than just my car. That said, there are a few things that keep this from being a perfect 5-star product. First, it’s definitely not designed for deep cleaning—if your leather is heavily soiled, stained, or dried out, this won’t be enough. You’d need a dedicated cleaner and conditioner for a full restoration. Second, the spray nozzle can be a bit inconsistent, sometimes giving off more of a stream than a fine mist. It’s not a huge issue, but it can waste product or make application less even if you’re not careful. Lastly, while it makes leather look clean and refreshed, it doesn’t provide as much conditioning as some other products, so if you’re looking for something that really nourishes and protects long term, this is more of a maintenance step than a solution. Overall, though, I’m very satisfied. The Chemical Guys Leather Quick Detailer is perfect for keeping leather looking sharp between major cleanings. It’s fast, effective, and leaves behind a clean finish without unwanted residue. It saves me time and keeps my car interior looking well cared for, which is exactly what I want from a quick detailer. I’d rate it 4 stars—an excellent product for regular maintenance and touch-ups, with just a few small shortcomings that prevent it from being the ultimate all-in-one leather care solution.

Great leather cleaner
Size: 16 Fl Oz (Pack of 1)
Bought this because I accidentally got some sunscreen stains on my leather interior in my car. Just a quick spray of this and a wipe with a microfiber towel and the stains are gone! Very pleased with the product and would definitely recommend to anyone who is looking for a nice leather cleaner!
