BMW 4 Series F32, F33, F36, F82, F83 (2013 - 2020) Dual-Mount Rear Differential Bracket - PFR5-4030 Supplied complete with M14 bolt, thread locker and Powerflex keyring. The bracket comes on its own without bushes, so you can choose to use it with a variety of bush combinations. Single OE bush, Dual OE bushes, Single OE bush with single PU bush (1 x PFR5-4026) or Dual PU bushes (2 x PFR5-4026). We would recommend dual PU bushes ideally. If you wish to use it with a single OE bush with a single PU bush, then the PU bush would fit in the vacant right-hand mounting hole in the subframe. With the newer F8x M2/M3/M4s making big power and having superb chassis straight from the showroom, it's no wonder they're often found at the most serious of track-days or at tuning shops across the globe. Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicle components, most notably the rear differential bushes.Despite having the provision for two mounting bushes on the factory tubular subframe, BMW opts to use only a single offset bush to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn and softened. With hard launch starts and sudden and frequent on-off throttle changes, this puts the single rear OE rubber bush through extreme torsional and directional forces, resulting in accelerated ageing with failure often seen at around the 30-40,000 mile mark and an unsettled and potentially clunky rear-end. We are proud to release a high-performance solution to this problem, giving you the tools to re-establish rear-end stability on your F8x M2/M3/M4.PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminium and is designed to utilise the secondary mounting position on the OE subframe. With the addition of a second bush, this prevents the diff from twisting under load, providing benefits such as:Reduced drivetrain movementImproved throttle responseA more controlled and consistent on-off throttle chassis response. Improved tyre-to-road power transfer reducing wheel hopReduced strain on fitted bushes The corrosion-resistant Satin Black Anodised Aluminium Bracket is optimised for high stress and deflection whilst withstanding high torque loads but is designed to function equally on standard or modified vehicles with either a single OE bush or dual aftermarket bushes. Although the bracket can be fitted without the need to remove the subframe from the vehicle completely, we would naturally recommend combining Powerflex products by using our already hugely popular 80A durometer PFR5-4026 Rear Diff Mounting Bush for both subframe rear mounting positions with the addition of our PFR5-4025 Rear Diff Front Mounting Bushes for the front for the ultimate in differential control and a lasting fast-road or track solution. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!Shipping Notes

Durable
Size: Large
Excellent material. I wish the hole was a little smaller to keep the treats in better. Also wish they were a little larger and/or oddly shaped so as not to fit under the sofa. Still totally worth it.

Subtle, great dog toy design!
Size: Large
These things are amazing. Stuff them with peanut butter and treats and freeze them of course, but football spike them across the yard to drive your overly hyped dog nuts! And the hole allows you to safely pry it out of a tug battle , just a great design! And it can bobble across a small living space without getting lost like a ball would. Love it!

Treats fall out way to easy
Size: Large
Kinda sorta awful at holding treats in it, they just fall out without my dog even having to touch it really. I spread peanut butter on the inside of the toy and freeze it..works much better that way, nay, works amazing that way. I got this toy to stimulate his brain, so he’s either much smarter than every other dog or the treats fall out too easy..I believe it’s the ladder.

Great for enrichment treats for dogs
Size: Large, Size: Large
Great product and durable. We fill them with wet dog food and freeze it then give it to our dogs as enrichment treats. They love it. It’s super easy to use and strong against dogs bites and chewing

Keeps My Dog Busy and Happy!
Size: Large
I bought this 2-pack of treat-dispensing toys for my large dog, and they’ve been a total win. The rubber is strong enough to hold up against heavy chewing, but soft enough that it doesn’t hurt his teeth. I like that it’s large, so I can fill it with kibble or small training treats, and it keeps him entertained for a long time.
The best part is how much mental stimulation it gives—he really has to work to get the treats out, which helps with his energy and boredom. I also noticed it slows down his eating when I use it for kibble, which is a huge bonus since he usually gulps food too quickly.
Getting two in a pack is great value. I keep one stuffed in the freezer with peanut butter for a cool snack on hot days and use the other for everyday play. Both clean easily with warm water and soap.
✅ Durable and safe rubber
✅ Keeps dogs busy and mentally stimulated
✅ Doubles as a slow feeder
✅ Great value for a 2-pack
Highly recommend if you want something affordable, durable, and actually fun for your dog!
