Dougal at Shockcrraft in NZ can make any hardware you want. Probably out of whatever material you ask for. Other than that a local machinist could replicate what you want given a good example. Some of those hobbyist machinists that are into miniature railways can do excellent work on a small scale. A set of titanium ones would be the best bet but would be hard to machine. Aluminium work hardens and stretches, I wonder if there is a specified number of uses for their hardware? Just checked and Shockcraft have trunion bolts on the shelf. $100 NZ for a pair of generic heavy duty bolts. $55 NZ for a pair of the OEM bolts.
Most frames they are not generic. A lot of them are custom sizing. Look up the price for top and bottom shock bolts for your trek slash. Trek wants nearly $100 per bolt!
Yeah I meant the trunnion bolts i assume are generic. I went through that whole bolt fiasco when I put a coil on my slash. Crazy money for a couple bolts and shafts
@@mtbtelly5522 Those bolts are made in house by the frame manufacturer. You're not going to find the same style bolt just off the shelf. There are a few companies who make upgrade bolts in stronger materials, someone already mentioned better bolts for example. Those flanges on the bolt head were never intended to see any loading they're there to shield the bearing. The trunnion bolts should bottom out in the shock just before the flange makes contact. Bikes flex significantly under riding loads they probably are making some contact which is what's causing them to fracture. This is why you're seeing some frame manufacturers switch to an eyelet style shock mounting where the shock has a bit of wiggle room. I recall some people were having issues with trunnion shocks blowing up seals because they were bearing too much load as well.
I agree, Nathan and Giant Adelaide have always been super helpful.

Oh killa! Thanks man
Cheers mate, try better bolts, they do titanium bolt kits for most frames. It is expensive but they should be much more durable.
Thanks
There's a brand called huk tek hardware that make trunion bolts for a trek slash. Like you said, they're probably all the same
I use the Huk Tek bolts for my Evil. Super durable!
I keep spares on me, just popped one this arvo. Maybe the shop can sell you an extra set.
Burgtec?
I was quoted an insane figure to get a replacement bolt because I had the buy the full set. I think it was near $200
Ludacris
I found some titanium ones at HukTek, 135 delivered from usa for a pair
Link man?
can you go to a machine shop and ask them to make a heavier duty one?
I think thats gonna be my best option

@@mtbtelly5522 my LBS who only do Giant gave me a bolt off some bike. The flange was too small, so water/dirt etc could get in really easy.

I think I have some spare bolts for you
Oh rad. How did you come across them?
