Looked in my tunnel section of my sled and noticed a 1/4 inch black strip going down the tunnel on both side, are these tunnel protectors stock since i do not have studs yet? Are they supposed to cover all the fins like 2-3 inches wide?
Those tunnel protectors are protecting your heat exchangers(the fins), the tunnel protectors are so your track doesnt slap/hit them. I put 1 inch tunnel protectors in with my 1 inch studs. Better safe than sorry, and there not expensive. you would probably be okay with 3/4inch protector.
If you take the protectors out and mesure them theyu are a 1/4inch high, and you should probably put the 3/4inch ones in, it wouldn hurt to put 1inch protectors in but there close with the track. so i also had to drop my tyrack one hole.
I would definitly use the 1" protectors because i used 3/4" protectors with 1 1/16" studs on my old sled and hit a pretty nasty jump which bottomed out the suspention and the studs ripped the crap out of my heat exchanger.so just likecrazy northern rider said Better Safe Than Sorry.
A friend has a '99 summit x 670 and one tunnel protector is missing and the remaining one is 1/8" thick. But there are no studs. If not, why are there tunnel protectors and do I need to replace the missing one? Are they to keep even the rubber of the lugs from hitting the fins? I bought one from Royal Distributing, but it is about 3/4" high, while the remaining original one is 1/8" so it'll look pretty stupid (although nobody will see them). I nearly returned it, but shipping was worth 2/3 of what I paid for it so I kept it.
