Looking for a rebuildable mtx skid rear shock. Would have to be 17 1/4-17 1/2 center to center. This ski doo shock from eBay meets the inches. Just wondering if anyone has ran these shocks in their mtx skid. Before I pull trigger. Or if anyone has other recommendations. Thanks I’m advance!

Thats not worth $250. Shaft is pitted. You need to check the travel and the length. Never had one on to see if valving is ok and if it clears everything.Looking for a rebuildable mtx skid rear shock.

Some phazer 121 models had rebuildable shocks. I'm pretty sure the mtx is the same shock dimensionally. I have a few in stock. I will double check center to center length on them.

121 piggyback is shorter so it doesn’t bring sled all the way up. I have one. Think center to center is 16 or 16 1/2.Some phazer 121 models had rebuildable shocks. I'm pretty sure the mtx is the same shock dimensionally. I have a few in stock. I will double check center to center length on them.

The 121 shock is not shorter. I just measured one here in the shop. 17.5" center to center. Crossed some part numbers between 121 and 144 and both share the same arms and linkage. Springs interchange between 121 and 144 so just different rates depending on year and model.121 piggyback is shorter so it doesn’t bring sled all the way up. I have one.

Interesting to know. Been told the piggyback from a 121 skid didnt work cuz it was short. I have one in my skid now because I blew my other shock. And needed it for 2 more trips. And guy I get parts from just sent me a pics of a piggyback that measured 17 1/2 center to center too. So guess ima get that one. And buddy’s 121 phazer will take this one.The 121 shock is not shorter. I just measured one here in the shop. 17.5" center to center.
