Well I had purchased a freshly rebuilt TRX shock with the hopes and belief I could bolt it right on minus the different bottom mounting bolt diameter but I found a bunch of other things different (that caused problems) in the process. So here, as far as I have been able to tell so far, the differences.
TRX shock slightly shorter (will lower ride height about 1/2-3/4 of an inch)
TRX shock slightly larger bottom linkage bolt. You can maybe get away with using the stock smaller ATC bolt but I would not recommend it.
ATC shock's top mount has a wider width bushing that is made into the shock and cannot be removed. The inner removable bushing will fit into the TRX shock but it is only supported by the smaller portion of the TRX shock. Your outside bushing dust covers will not fit and stay on by themselves. The TRX shock will have 3/8inch of side to side play at the top of the mount without custom made centering bushings.
TRX shock canister hose mounted to the shock body in the upper position. End of the hose and the banjo bolt head will hit on the main down tube of the frame where the airbox hooks on, and also prevent it (airbox) from going on completely. You an loosen the banjo bolt and twist the hose out of the way but you will lose most of your shock oil and probably 25-30lbs at least of nitrogen charge.
Canister hose is longer on the TRX, and mounts to the canister itself at a different angle making it very difficult (not impossible though) to mount in the stock position. Hose will rub on shock spring, and airbox externally though when mounted.
So thats what I've found...don't buy a TRX shock and expect it to be a bolt up in 30 minute job, it aint.
