Collection: ARRMA 4S series upgrade parts

Really nice stuff - goes together well - very much helped the performance of my FMS rig

Great product

Seem like very high quality still only running at 50% power these are expensive don't want to snap them too. It would be great if these were made in a size to fit the plus 4 mm injora axles

everything arrived quickly and parts are great!

Fast and easy process to get a replacement part

Worked great on my rig. Less than getting super 8 axles

It fits. It works.
BUT
You need to shorten it by about 20mm. Another review said an inch but that's a tad keen for me but what's 5mm between friends?
I also used the OG center bearing (ARA610038) and a bearing from the diff (ARA610044) to make a centre bearing/Support. Basically put the little bearing inside the big bearing. Works a treat!

Excellent product great upgrade highly recommend this product

I installed my new oil filled shocks and weighted wheels, and noticed an immediate improvement in handling. Top quality, good looks, and value. Thank you. B. Miller

These hubs work great. A lot stronger than stock.

excellent product, will buy RCAWD again

excellent product

The axle fit just fine. I think the cross pins are a little big making the axles pretty week.

Extremely happy with upgrades but I ran into an issue with set screws for drive shafts in trying to order more and got zero support and no help at all

This is the only aluminum driveshaft on the market that fits the Arrma Kraton 4S V2. I tried the brand sold on EBay first and it was too short had to send it back. Very simple design compared to the oem driveshaft. Super lightweight and strong. What more can I say. Buy it now!
