Full replacement Differential cup/case set for the HPI Baja (all models - 5B,5SC,SS,5T), This cup is the same dimensions as the stock HPI cup/case so is a direct replacement part.

Diff cup/case is made from high grade 7075-T6 for the best weight to strength ratio and long life. Anodized in a clear finish comes complete with all internal parts shown (diff gear holders,Bush B080, bearing B030, O-rings, Seals, Hardened and ground drive pin (4x18mm), 2x shims and fixing screws (M4x16 BZP socket cap)).

Please note, we recommend dry assemble of the diff first to check gear mesh & shimming for best fit and readjust if and where needed. The included 10x16x0.5mm shim is used to replace stock shim 87474.

We have also included 4x special Oil filled bush to replace B080, these release oil over time to help lubricate the dirve cup shaft and give very long life. (we no longer supply the little bearings as an option due to them collapsing under the heavy load of modern high performance RC engines - bushes are just superior in all ways as time has proven)

Very good quality
They are firm enough for dogs to have them in their mouth but not to hard. They bounce nice and more then once. I will purchase again if my dogs wear theirs out

Very lightweight and not good for fetching
These balls are very lightweight. They feel like styrofoam. I try to use my Chuckit Chucker to throw them but they don't go very far and the wind will drift them in another direction as they are so light weight. Then, when my dog's saliva covers the ball, the moisture creates a suction in the launcher and the ball won't exit the chucker at all no matter how much force I put into the launch attempt. I guess they might be good for chewers, but not for throwing, if your dog likes to fetch. They would be good for throwing in the house as they won't damage anything.

Shockingly impressed
I have a heeler and he destroys everything. I thought I was going to be unimpressed at first thinking these were going to be shredded everywhere, but I have yet to see him destroy these and we have had them for over a month. I definitely recommend for high energy aggressive chewers.

Cheap and easily destroyed!
I bought these balls because they are advertised as indestructible. Frankly, tennis balls last 5x longer! We breed Cane Corso, and these don’t last even a few minutes with them. Definitely not indestructible and definitely not for aggressive chewers. Very disappointing. The search continues….
