Hi, This is possibly the wrong part of the forum to ask (but I am a newbie).
Has anyone got advice/experience of a drum brake to Disk conversion on a 1974 XLH Ironhead sportster or similar? Looking to possibly do the same.

 

You need to find a swingarm from a 1979 to 1981 Sportster, part number 47532-79A, or possibly 47473-80. That is the beginning of the project and the most essential part. Others are looking for this also so you have to be actively searching eBay and other sources.

I have not dome this myself so that is about the limit of advice I can offer. Also post your question on any other IronHead related forums.

 

Thanks Mick, I am still unsure as to whether I will do it or not, but will have a look at the Ironhead threads.

 

With a disc brake already on the front you have reasonable good braking for that vintage. The drum on the back of mine can lock up the back end. Is your rear drum in good shape with shoes and moving parts? Given your location sourcing parts could be challenging as well. Good luck whatever you decide

 

Thanks for the advice, I am leaning towards keeping it as is, as you say, sourcing parts to do the conversion here is challenging. I may get the front disk vented to give me a bit more up front.
