Are There Any Companies That Still Make Extended J-Arms?

[banshee1999]

As the title says, im looking for some extended j arms, but they seem few and far between. I see that Fireball racing but they are getting up there in price. I am considering making my own chromoly ones, but I don't know if I can fully trust my suspension design skills. is there any other companies that make them, or is Fireball the only option?

Actually, this is now what I'm planning on doing. I have knowledge of suspension design from FSAE, and I am a pretty good gas welder, so it's worth a shot. worst case i just waste a few hundred bucks. just gotta figure out what chromoly tubing to use. I might make another thread outlining my process but we will see.

I was joking. Don't waste your time or life.   If you really want to be stubborn, talk to tfaith on here, he knows suspension/and fabrication of it.

I thought it was a joke, but I'm always up for a challenge  , and you're right; I am stubborn and cheap and don't really want to spend a grand on some arms, but that's just me. I've made some custom billet parts with my university CNC machine, but ik suspension is a lot different. ill reach out to Tfaith to talk suspension, thanks!

Waste a few hundred? A set of arms won’t be much more.

I think I am going to wait until all the parts come in and get the bike running before buying/making J-Arms. No point in having new arms on a bike that doesn't run!
