It can be done and from what I understand you will get the full travel. The local dealer has done several zrs and exts. We plan to do it to my friends 95ext 580. I talked with the mechanic and he somewhat explained it to me and said you have to redrill some of the holes. He is going to show me once we get a skid to put in. Hopefully we can get one fairly soon.
i would still wonder about putting the skid in a older non ETT sled. Arctic cat kinked that tunnel for a reason and that was to increase travel but not the ride height so much, if you put that skid in a non-ETT sled and want it to have the full travel the back of that sled will be so high off the ground it will change your center of gravity destroy one of the best handling trail sleds i have ever ridden, i have a 96 ZR 580 EFI and i came from a 97 ZL 440 which had the ETT and i dont miss one ounce of that travel i lost. the pre 97 ZR's in my oppinion are one of the best trail sleds to this day
I've seen one that the dealer did and it seemed fine to me. I agree zr580s rule that is a great suspension for flat trail riding but just doesn't cut it in the bumps. I will post some picks and dimensions once we get the projet done. I think we've found a skid so we should be getting around to it soon.
the skid is what dictates travel, the tunnel is just for track clearance
you mount the rear portion of the skid in the lower posistion on the
tunnel and no problems. I also have a skid for sale with the fox shocks
if any body is in need.
I am putting a skid from a '98 ZR into an '86 Phazer. I haven't put it in yet (waiting for new rear brackets to be made), but I've modeled it all and decided on new mounting hole locations. If I remember to, I'll post the dimensions tonight.
