I have 2 sets of RR front caster blocks, one 20deg, one 30deg. I was going to use them, butnoticed that they do not hace a spot for the camber-link ball end to go, and the king-pin holes are much bigger than the standard pin.
Did RR make a front end system of some sort that these go to?
Also I've got 2 pairs of monster truck "axils" for 18deg kingpin.
These have a similarly large hole for the kingpin, but it is not perpendicular to the axle like every other axle I've seen. What do these fit?
Thanks,

yup, robinson made a complete 18 degree king pin/ castor block kit. they had the for the rc10/t (rrp 2020/30), losi (rrp 8520/30), and traxxas (rrp 3520/30). the ball stud screwed into the top of the oversized kingpin.

this setup also came on my trinity reflex-10 pro from the factory back in the day.

Thanks for the great pics and info. What is the advantage of this system over stock geometry?

it has something to do with the pivot point of the wheel. i'm not sure how to describe it, though.

edit : it puts the wheels pivot point under the tire. that's what their ad says.

Cool pics!
