Robinson Racing JRXT Rear Block - Computer Machined RRP-8504

[adam lancia]

Anyone ever heard of or seen these suckers....? They look like they might be for the H-Arm setup but I can't be certain, I've never had a JRXT. I picked them up from my LHS today thinking that someone on here would know what they are. I'll get some pictures up in a bit.

These?
They go along with the machined rear arms from RR. I do not know if they made any parts other than these 3, if anyone has any additional info please let us know.

Yup, those are them. They made arms too? Funky looking stuff, any idea what the material is? I suppose since you've already got a pair you're not interested in another....?

[aconsola]

I actually have an extra pair of rear arms to go along with your blocks if anyone is interested.
The material looks like some sort of plastic, but not delrin I don't think.
I wonder if the RR people even remember making these?

I emailed RR, and they replied that the material is PVC

Thanks for the information Anthony.

This means that you can modify/repair these by using the appropriate PVC materials and adhesives. (I have a pair of fronts that are "swiss cheesed")

Rgards,
