You might not need them on that sled, If the coolers are lined up with the hifax and track clips, you should be fine. If you want to do them anyway... you need to remove the seat and fuel tank, get some aftermarket tunnel protectors, and screw or rivet them in. They look like tall square or channel shaped hyfax. You will probably have to cut them to fit with a hack-saw or wood blade circular saw. Make SURE you get the kit to protect the crossover hose in the rear of the coolers, the studs can cut right through it. Look underneath at the rear, and you will see the hose. Kit is real simple and just rivets on.
The big thing is make sure the protectors are not lined up with the studs, or you will just cut them to shreds.
Some like to do the kit to protect the front cooler...I have never had a problem with the studs hitting it, but if they are too long or the track is too loose and it jumps a cog on the drive sprocket, they could hit.
And, I agree with the rest, I never ride without studs, especially in lower Mi. I wont even let my kids ride without them. A nice V pattern works good for studs (96)
