I'm a Timbren man myself.
You can shop online or contact the company directly. You can get spindles capable of accepting electric brakes on pretty much any Timbren Axle-Less suspension, which range from 400 to 1200 to 2000 to 3500 pounds capacity and up.
Be prepared to pony up, though. They're designed for light- to extremely heavy-duty off-road campers.
TorFlex is good to, though. But all of them are made-to-order.
The cheapest solution is probably to get a regular 2,200 axle, specify the correct hubs for brakes, and then order separate leaf springs rated for whatever you need. Nothing wrong with that. It can be difficult to know which components to order, though, so if it's your first time, talk to a sales rep at a trailer parts dealer.
And yes, you'll have problems using too big of springs. In extreme cases, it'll be like you don't have any suspension at all!
