I have a cheap walgoose and have a bad idea to make a 20 inch dirt jumper, But I want to convert to threadless for suspension. Any tips or forks that'll fit?

This is way too vague. Of course there are forks that will fit. You'll need a new headset and fork that are the correct sizxe. You're probably gonna need to do something w/ the front brake...is it rim or disc? Provide some info or we can't help. I'm not going to go fork shopping for you either. That's up to you once you figure out what you need.

Yeah I figured, it's a Brawler BMX and Walmart doesn't say. So I didn't know if anyone knew what the size was, and if the bearing cups will work the same.

Honestly, this project sounds like something you really should consult with a bike shop about before you invest money into it. A basic Suntour XCR fork costs $200, and you'll need a new headset, and to make sure your axle is compatible. Going to all this trouble for a $128 Wal-Mart bike freestyle seems ill-advised.

It's gonna cost more than a new bike to get it done. I'd just hit up an LBS and get something else.

What's the front brake type? rim or disk?
