B4.1 Parts Needed?
 

I'm ordering a new B4.1 Worlds kit and would like to know what spare parts I should order. Thanks.

front A-arms
caster block's

i keep at least one full set of bearings spare in case i blow one out. (front and rear)

RPM ball cups

also grab some of the shims that are between your caster block and steering knuckle as they tend to run away when you break a caster block.


for the most part if you lawn dart it, it puts the load on the A arm.

if you hit a pipe you break a caster block.

so far im down like 4 caster blocks and one a arm in about 2 months of racing once or twice a week.

I bought one of these buggies last year after nearly 10 years of not running anything at all. With a 10.5 in it, I beat the living snot out of it learning how to drive/race on dirt again, and didn't break a darn thing.

They're tougher than they seem, even with lawn darts and sumer saults down the back stretch. The standard parts are WAY more forgiving of incidents than the carbon parts.

That said, I ALWAYS keep a spare set of Avid bearings, front and rear A arms, C hubs, steering knuckles, suspension hardware, and spur gears. So far, due to a particullarly hard nose in lawn dart, I've only had to replace a spur due to a shifting motor and a gear cover due to a loose pinion (melted all the way through!).
