Im thinking about changing my nuts&bolts to titanium, thoughts?
does anybody have a list of the bolt length for a majority of the bolts on SJ?
Ive got the manual but it doesnt tell you the length
Thanks

Titanium fasteners will be ridiculously expensive...especially in M10x1.25 that we need so many of. Since titanium elongates more than stainless, I think you'll find that a lot of your fasteners are going to vibrate lose over time. Titanium works great in shear but it's not as good in tension applications and all of our bolts are loaded in tension.

On a side note, there used to be a list online somewhere that had a big excel style sheet of all the fasteners and the lengths. I think I have it bookmarked at home but I'm still in Daytona right now.

my buddy races dirttrack and some of his competitor will spend 2-3K on titanium bolts to loose 4-5lbs. every bolt on the entire car gets replaced. If every bolt was 1/2 the weight of the stock hardware then you could loose some decent weight, i just don't think it would be half. let us know what you find out and how they hold up. i bought a bag of bolts and hardware off ebay once and it was heavy.

I did the Ti conversion on my last CRF450R and it was a total pain in the azz. I had to use loctite on everything that was Ti due to all the Ti bolts kept vibrating loose.
IMO it is a gimmick that is NOT worth the money!
 
Ti would be a last effort after all other options have been exhausted. You would do better to get a lightweight hull first than spend a couple grand on bolts that if not kept up with could cause an engine failure. I thought about it once also but decided to go on a diet (alot less expencive).

Why do you want to do that?

Ive got some buddy in motocross and they have done it for weight issues, So I figured I would look in to it

I want to get all new hardware for my new superfreak too. I'd be interested in the lengths also. Where are you sourcing the titanium fasteners?
This is the best site ive found so far and wow are they sexy! You can even change the color! It would be sweet to do just your head with these for the sex appeal lol

That I didn't know, Good to know defiantly something to think about

Dont you loctite everything on your ski anyways...I put that poop on everything!

depening on the bolt, yup, clean threads and a dab of lube/anti sieze and that is all i use. i do tend to check my torque once in a while but i usually do a pre ride inspection before heading out to the water so i am not wrenching at the beach. loctite isn't supposed to be holding your motor together, torqued bolts are, just like 1211 isn't supposed to be what is sealing your motor.

to get proper torque settings, bolts are actually supposed to be greased.

NO THEY'RE NOT! Unless the person that measured and determined the torque/tension says so. There is a huge difference in tension between dry and lubed hardware for a given torque. The finish of the bolt face has a big effect on turning friction. Be very careful when using a torque wrench with wet hardware, bolts can be pulled out of their threads long before the torque value is reached. Its is a lot better to snugg down bolts and turn them a certain amount after that rather than guessing how much tension is on the bolt by how hard it is to turn.

i never worry so much about the torque # but rather that they are all the same and tight enough to hold. I like to finger turn in my bolts. My buddy had a few problems on his subaru STi motor when torqing his head studs. stretch bolts can have some crazy torque sequences and still screw up/fail.
