- Hardware
You will need:
- For Axle Mounted Servo setup, the optional BRX70 aluminum servo mount is needed.
- For Chassis Mounted Servo setup, a panhard link is needed (as almost every car has a different setup, we leave this part up to you).
- For Leaf Spring setup, additional optional parts may/may not be needed depending on your setup. Leafs can be mounted directly on top and under the axle.
When you receive the axle:
Make sure to grease up the axle set. You can fill up the empty space with diff grease surrounding the bevel gear and input shaft.
The gear positions are factory setup and should be ready to go. Rotate the drivetrain by hand for physical inspection.
Install spacers accordingly between the center driveshaft and the input shaft to prevent input shaft from unnecessary slop.

- Steel Leaf Spring Channel w/ Shock Mount for BRX70 / BRX90 Axle (2) BRLC7002/B
- Aluminum Knuckle Arm (Low Profile) for BRX70 / BRX90 Knuckle (2) BRLC7010

Gave my dog diarhhea
Size: 0.06 Ounce (Pack of 16)
I love the design of these toys - keep my pooches busy for a good amount of time. However, these treats gave one of my babies diarrhea, possibly due to the sorbitol, a known laxative for dogs :( My dogs are both ~11lbs, and they would only get one disk at a time in their toys, and still one had loose stools. I know it's not the rawhide because he dosen't have trouble with regular rawhide, but these are so soft I can only assume they have too much of other ingredients inside.
Update: I just tried the dental disks and my boy that was sensitive to the regular refills has no issue with those. There's definitely an ingredient in these which he is sensitive to.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.

Crumbly, odd texture
Size: Large, Color: Duo Pack
Neither of my dogs were very interested in these. They did chew on the antler-shaped versions more so than the infinity-style versions. When they did chew on these, they didn’t hold up well or last long. These have a strange, crumbly texture when chewed. You’ll find bits and pieces of these chews where the dogs have been chewing. Will not be reordering.
