I'm not sure what theyean by align the c clip with the d shape? I assume that's just how you get the axle to fit through the knuckle? Anyway, thank you for the help, I greatly appreciate it!

Are their bushings that go on the top? If so where do you get them ? On my old plastic servo saver it has bearings.

Thanks, Brian

My kit came with bearings, but I'm using the avid rack and never messed with the servo saver shenanigans.

When using the Avid rack does it use bushings? The holes on the top and bottom are recessed.

I have bearings in all four holes.

Mine that were in the old setup are to big.

Is this an upgrade kit? Or from another kit? The B4.1 Worlds is not hex out o the box right?

its the hex option that came out for the sc10 first and now for the b4,been out for some time

Do I have to piece it together or can I buys it as an upgrade kit?

Avid RC sells front/rear hex together. The rear hex is a simple replacement . The front you need to buy the option threaded axle AE sells shown above.

this is my question,do you own a rb5 or have tons of fr hex wheels,if not why would you want fr hex,you cant rotate them to the back.i'm not doing fr hex on a buggy in my opinion its a waste of money

i wouldve went front hex a long time ago if i didnt have so many standard wheels for the front. i'd love to be able to borrow tires from fellow K drivers.

I currently have a B4 FT ( I am sure this question was asked before). What are the differences between the B4 FT and the B4.1 FT? I went throught the manuals and this is what I discovered. Let me know if i am missing anything.

1) Rear Alum Hubs (.5 deg), but most setups are 0deg hubs.
2) V2 shocks
3) V2 Slipper? (Worlds only?)
4) Chassis? B4 to 4.1, not worlds.
5) Battery Strap (has thumb screws
6) Body/Wing (lol)
7) TI Nitride Ball Studs?

there's too much to list and it will cost almost if not as much as just getting a new kit.

I agree. After looking at it, I decided not to bother. I like hex better than wheel bearing, but not a good enough reason. I have a 4-5 year old B4 FT that I am dusting off and trying to decide what I want/need.
