Default rc8 bearings

today i was rebuilding my car and i decided it was time for some new bearings. and i started to look around for ones. and i decided i wanted to go with avid revolutions bearings. (dont want to spend the big bucks just yet on ceramics) i went to start adding the bearings i needed to my cart and then could not remember the sizes i needed. so i went to the manual i downloaded off of ae's website and well it says the front bearings for the steering block use 1 - 15x21 and 1 x 8x15. and the rear hub uses 1 - 15x21 and 1 - 8x16.

is this a typo and the front also use a 8x16 or does the front really use a 8x15 cause no one makes a 8x15. and i even went to acer racing to look at there bearing set and it says it comes with 14 - 8x16 and no 8x15 bearings.


thanks.

The bearings used in the steering knuckles and the rear hubs are the same.
8x16x5 resp. 15x21x4

ReadyRollers.com sells a set for the RC8. It comes with all of the bearings even the ones for the steering.

Don't forget Boca Bearing's they have .99 cent bearings also and they fill their orders fast. Great people to deal with and Im not just saying that because they sponsor me. Here is the link to the RC8 kit:

88, Try Acer Bearings. They have a ceramic Nitride kit for the rc8 that is really great and priced good. http://www.acerracing.com/products/ASSOCIATED_RC8_RS_Ceramic_Nitride_Pro_Series_Ceram ic_Ball_Bearing_Kit-624-12.html

Also try the Sin Lube.

I run the Acer kit as well and they are sweet. In fact too sweet I changed all my 8x16s over to Panthers. It makes the car feel like it has a little of drag brake. Helps a lot with the flat sweepers we have at our local track.

I have a bearing related question. I just picked up a gently used RC8 for the upcoming race season that I'm about to tear down/inspect and am seriously considering picking up a ceramic set. How much longer do they last compared to the typical sealed bearings? Do they really last long enough to be worth the added price?

Ceramics roll with less friction. don't know how much longer they last cause I never had the nutz to run them. I was advised to onlyuse them on the diffs because the wheels get to much abuse . you know side load a such. They for sure free up power with the friction reduction. Anybody else with more experience want to handle this?

I dont know that much about bbearing but from either hot mods or rb mods or even tnt mods they put ceramic bearing in one motor and regulars in another both same motor and put it on the dyno and the end result of every test was the same.. They said ceramics make no difference!!! Just thought I would put it out there!!!

Default Ceramic bearings

There is no side load issue with Ceramic bearings. They will absolutely not break or shatter and in fact are much harder than the steel balls in non-ceramic bearings. So they will definitely be a speed and durability advantage to non-ceramic bearings. Thanks for the kudos JoeytheRocket sounds like our RC8 ceramic bearings were a little too fast--best of luck at the track and at the races with your new setup.

This hobby is the best, we appreciate all your positive comments and the great information everyone is so willing to share with each other, that's what keeps this great hobby so enjoyable.
