Hey there Mohan.

The Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs # e37YR you were looking at already has an idler hub on it which is not setup for brakes. You would need to replace the axle with something like # e78GR with brake flange welded on # 4-34. Then you can add drum brakes to the setup.

Let me know what you're thinking or what exactly you're trying to do and I can dig deeper for you!

Thank you for the reply Andrew. Does the #4-34 comes welded on to the #e78Gr or do I have to weld them?

@MohanM Sorry I should've been more clear. You will need to have the brake flange welded on. Unfortunately I don't know of any 2K rated axles in that size that come with the brake flange welded on already. It's best to have a trailer shop or good fabrication / welding shop do it as it needs to be completely squared up and true. If it's a little off, it can mess up the brake and wheel alignment.
