Better, More Clever Than Brass.

First, I got a set of these from a LockedUPRC vendor. Oddly enough the package contained two driver side knuckles. Was kind of funny, but LockedUpRC got me squared away quickly, treated me like a valued customer, not just some random "who cares". Anyway, they mount up very well, they are exactly spec, so I did have to trim some metal off a pair of SSD portal covers to fit. These knuckles are burly nice and beefy, without compromising rigidity or durability. Much better than masses of brass hung on the axles or much much worse, brass added to wheels or any other rotating part. Terrible idea. Anyway, these are heavier than aluminum or OEM Plastic without being sledgehammer overkill, stronger than OEM, NOT just Heavier is a real nice balance. As I said, they look great, different from pretty much anything else out on the market, they appear to be bomb proof, and LockedUPRC's customer service was epic. Been running them hard, and there's been zero wear. They match the rear Portal covers also from LockedUPRC very well and over all I'm super pleased. Recommended.

Q: On the black steel knuckles for the traxxas trx-4 i noticed there are only 2 screws holding the bearing in compared to 3 stock. Will this have any ill effects ? or doese it not matter? Thank you.

Asked by: Shane Helt - 4/21/2020

A: No ill effects. This is going into steel instead of plastic.

Thanks!
