250R and 450R shock shaft - same or different

Recommended Posts

Bike: 2006 CRF250R

While servicing my shock (my first attempt at this - oil change +), I decided to fully disassemble and clean everything as well as learn about valving, etc.

While removing the shock shaft nut, I tried to follow instructions to file off the peening but apparently I did not file enough and I ended up wrecking the nut and more importantly the threads on the shock shaft to the point of being not repairable so I will be needing a new shaft.

My plan is to buy a complete used shock and use the shock shaft off of it.

My question is: are the shock shafts the same on a 2006 CRF250R as a 2006 CRF450R.

The reason I ask is that I found a brand new shock shaft on EBAY for a 2005-2008 CRF450R.

I checked part #'s and for a 2005-2008 CRF250R the part # is: 52426-KRN-711 ($225) while the part # for a 2005-2008 CRF450R is 52426-MEN-711 ($188).

Thanks for your help.

There's a reason the part numbers are different.

There are a bunch of shocks on Ebay that would fit that bike. If It were me I'd just buy a used shock.

Another and maybe better option would be to call a suspension specialist like Factory Connection. I'm sure you are not the first person to have that problem. I'm sure they have a fix

If the the clevis is the only difference and the rod is otherwise the same, can I use a 450 rod and screw it into my 250 clevis?

FYI - I found out that the clevis's and rods are different between the 250 & 450. The threaded section of the rod/shaft that threads into the clevis are different lengths.
