'56 rear shocks

As I look to rebuild by '56 khk, I've run across NOS shocks on ebay or new replacements from other sources such as J&P. I have found shocks that look similar to a k-model, but not exactly in the after market stuff. Will a later model sportster shock fit my bike and will it look correct? Thanks again for any suggestions or help.

Re: '56 rear shocks

I would think the 67-72 shock assembly would work for you. IIRC, they are 13 1/2 " eye to eye.

Re: '56 rear shocks

I'm looking to bid on a set of rear shocks on ebay...can anyone tell me if they will fit and look correct on a k? I've emailed the fellow who is selling them and asked him the same question, but I'm not sure if he knows any better than I! Any help is appreciated. the Item number: 190231743255 in on ebay.

K56, those shocks will work perfectly. They may be 1" longer than the standard 56 K shock. In 58 HD offered the longer shock as standard equipment or an option, not quite sure which, to offer more "road clearance". Standard length or 1" longer they will look and work perfectly. And DChasteen's parts are the best. Bid with confidence. I have many of his parts on my 56 KHK. For the true purist they have the early Sportster A - B stamped lower cup. 56 K's lower cup would be stamped "R" but look the same and function the same as the AB cup.

Re: '56 rear shocks

Longer shocks will work BUT they will change a few things. The swing arm angle will be more thus the bike will react to the throttle more. You should feel the seat riase up a little more on a hard throttle up do the the tire trying the plant in self in the pavement. Some call this "Forward Bite". It may also efect your chain clearances and lenght as the efected leanght will now be somewhat shorter unloaded HOWEVER as the shock compresses it will grow. You'll need to use a Heavy freind or a ratchet srap to set the chain loaded. Once you load it so the swing arm it level and chain is properly tentions you then can unload it and measre the chain slop to the swing arm and write it down for future quick checks.

So, I believe you are saying to stay with the 12.5 eye to eye originals shocks? Any ideas where a fellow could find a good set of those?

No just be awhere of the change and check the chain clearances.

Re: '56 rear shocks

44dwarf I really like your machine - you have to post more pics!

k56, just go for 13.5 or 14.5 early K or sporty shocks and perhaps choose the length based on your height and type of riding? (how many people really offroad their sporties these days?)

The shocks on my KH in the other post were bought off ebay for $5.00 + flatrate shipping from memory. The earlier ones will set you back more (especially with covers), but there are cheap easy options out there.

Caveat emptor with used parts as always though.
