Not what I expected
Had issues with this drivetrain set. Does not work with Metal Differential housings. Carriers cause interference with housing and drive shaft won't spin freely. Seller told me that I'm not the first person that has encountered issues with this setup. They should design the diff housings to match the Carriers they sell, Not impressed

Main gear doesn’t fit a959b
Main gear too small for the a979b. That was the main part I was missing so now I have to reorder a separate gear for no reason.

Awesome Kit
A must for any A959/B owner looking to replace factory plastic diffs. Adds such better drivetrain tolerance. Very nice. Highly recommended. Took a few weeks to arrive but I'd rather wait three weeks than pay three times as much for someone to sell to me on US soil.
