My replacement Heim Joints from Skinz just arrived.

I sent my A arms in to update to the 5/8" heim joints. I just don't want to take any chances something letting loose at 85 mph down the trail.

If you want the skis to bite harder, lower the pressure in the front skid shock in 5 lb increments until you get desired feel.

I have run the Skinz kit with Gen III's and the Curve XS skis - and yes, there are huge differences.


To answer an earlier question, the 1/2" CHROMOLLY heim joints have a 17,000 lb shear strength.

I hope that I'm already dismounted if I hit something hard enough to shear one of the new ones. I actually still hold faith in the old ones.

My new ones are here and I will install this week for preventive practice. Still going to ride the originals tomorrow. Better a heim joint in the field, than a sub frame. Besides with rope, duct tape and baling wire, I can fix about anything like that to get home.

SMX,
What was the turnaround time at Skinz for getting the a-arms upsized to 5/8"? Skinz have said its my choice whether to get them done now or in the spring. Just curious.

Thanks

I pounded my new 1/2" ones this weekend pretty dang hard including some really hard shots off some downed trees and no damage. I got a feeling they are good to go.

Did you go out today? If so how was the snow?

I have been trying to stay somewhat quiet about testing, but I have been running the 1/2" upgrades for around a month now (6-7 rides?)

As most know, snow conditions are much less than ideal here in Wyoming, and it is a veritable demolition derby every ride.

I have bounced off more rocks, stumps, and trees in the last month than the last 5 YEARS combined. Some of it is a "care to the wind" philosophy aimed at ensuring this kit will hold up - thus far, I have had NO ISSUES... and I am running the updated 1/2" rod ends.

Preliminary results are pointing towards the 1/2" ends being more than acceptable for brutal bashing. I will continue to run the 1/2" until there is a failure of the joints, or any other component (i.e. - subframe, shock, arm, etc.)

I am fully convinced that the 1/2" joint size was within acceptable initial design parameters, but the construction/quality of the joints that Skinz received from their supplier was the weak link.

If I encounter a failure, I will post exactly what transpires... but I doubt I will have to.
