WTB EU Matrix 2 Kingpin

[Chricious]

Since my kingpin has broken I would like to buy a new one.

This might help

Titanium Kingpins

Apparently these fit MBS Matrix II"s in addition to the Lacroix Hypertrucks.

Yeah, it’s just an m6 8x80mm 8x90mm shoulder bolt.

[Chricious]

So I bought an M8 80mm bolt and it doesn’t fit, because the MBS bolt is 90mm.

Dang, that’s what I get for regurgitating what I find on the internet. In my defense, this misinformation is straight from the source:

Not Matrix II related - FW4 bug causes wobbles

The Matrix II king pin is an 8mm x 80mm shoulder bolt. Note: Those are the dims of the shaft (not including the threads) - refer pic. The king pin thread spec (and associated nut spec) is M6. [image]

I should have just gotten off my lazy ass and measured

[MBS]

Sorry for the confusion guys. We’ve always spec’d our shoulder bolts based on the diameter and length of the shaft (not including threaded section). But I see how that’s confusing. Pic below to clarify.

. I updated that original post as well just to be safe.

[Chricious]

Why do you make the thread M6 instead of M8? The bolt broke exactly on the thread collar.

[MBS]

They’ve always been tapered like that (since the 90s). All shoulder bolts are. The breakage is weird. Could be a fluke but I’ll keep an ear out about this just in case.
