Just bought on '05 F7 EFI SNO-PRO and they said with the length of studs I need due to the sno pro track I need these taller nuts to prevent bending. Any issues with these?

I got the same sled, I heard the same thing....was just to lazy to put the taller nuts on.

Its true cause I have been bending studs.

Get the taller nuts.

I love that sled, it rips

no they are the best thing ever, I have them on my sled with 1.87 lenth studs and every one is straight. also a double backer pattren is real good. the are no more difficult to install than normal nuts, its nice to have a cordless drill and severl batteries on hand.

Studs should be just a little bit longer than the high parts on the track

Studding an '05 Sno-Pro...

I am curious as to how many studs you '05 F7 sno-pro riders are using. I know the track is narrower than the previous generation of sleds (13.5" vs 15", I believe) and I am wondering if that smaller width affects the number of studs used in this application. Also, I am considering getting an '05 F5 sno-pro (supposedly it has the same 1.375" deep 'paddle' track as the other (F6, F7) sno-pro models) and I am wondering what would be the reccomended number of studs for that sled ('05 F5 sno-pro). Have the studding patterns changed as a result of the narrower track? Thanks in advance for any info; I'm brand new to these Firecats (riding an '03 ZL600 EFI right now). I am currently using 120 Woody's Gold Diggers with AL backs on my ZL and am quite satisfied.

cats have a few more lugs on the track, regular 121/ 15 or 14 have 48 lugs. I am not sure how many the 128s have but there are more lugs on them. 96 should be enough, I would not recomend putting studs outside the rails.
