Best forward a-arms

pelon · Nov 19, 2013

I checked it out and your right. I guess what I'm trying to get at is, what is the true majority improvement on these front ends? Is it the narrowing of the stance, or does the forward movement of the spindle cause the most improvement. I realize the combination of the 2 most likely has an overall benefit, but whats the spit 50/50, 60/40......???

who has the new z bros and what's your take on the front end vs. stock

thanks

The biggest improvements are realized by moving the spindle forward and having the correct caster. Narrowing it.....not so much. I ran my last set of prototype arms last season at 39" and off trail performance was great.

I guess all I can say is that if you read the b*tching-n-moaning threads about how crappy sleds handle boondocking & tight technical riding.... almost ALL of them are from the AC/Yamaha camps. Both sleds come with 40" width or more front ends stock. I'd say 90% of us mountain riders could give a ship about "trail" performance as it's only a inconvenience too the hill!! It's ALOT easier to pull the sled over with a narrow front.
Case in point you don't see much b*tchin from poo/doo camps about boondocking/ tight technical handling? Mmmmm nope, they both come stock with 36" width front ends.

And yes mountaintech I also understand that proper caster with the correct weight distribution plays factors into this BUT for the ease of getting these sleds to pull over easier a lot has to do with width of the front end.

I ran the new z bros front end all lass season. It is miles ahead of stock as far as sled control goes. Down hill maneuverability is where I noticed the most improvement, night and day difference. I did play with the caster adjustment but I found the sled handled best with the z bros suggested setup and I haven't changed it since.

What were their recommendations as far as caster?

I don't recall, maybe someone that has installed one recently will chime in. Here is pic of the caster angle I'm running.

With our kit there is a spacer that can be ran in ether forward or rearward position on the top A arm. We recommend the rear position for most applications. The only time the forward application would be used is with a very long track or high sitting rear suspension. Like 174" M 10 set up.

I used a degree finder to set my camber. I never checked the caster angles.

I got my zbroz kit installed this weekend, hopefully I did everything right. The lower spindle nut was a fun one to get started, but once I figured it out I got it good and tight to the required torque.

Can't wait to try it out.

Can anyone tell me if these cr racing a arms are the 3" forward newest style? Sled is used and they look the same as the ones in the picture from crs web site

For the skinz yes I was referring to the pre-bent tie-rod ends. If you read some people's post they almost break if you look at them wrong. Other guys don't have any problems.
As for the ZBroz shock mount breaking I've only heard of that a couple of times. I'm not 100% if it wasn't rider abuse but who's to say.... Everybody seems to down play how "HARD" they are on their machines!

For me I'd go
CR Racing
ZBroz
Diamonds S
Anybody else's
Skinz(I will admit I've got a personal hatred with them)

Agreed on the tierod ends, I have rolled mine in deep snow and bent them. The curve in them makes them weak and bend easily when the spindle takes a perpendicular hit as it rolls over.

Needs a better design.

ONLY complaint I have about the skinz front end.

Saw this on TY uses stock tie rods and shocks +5 forward 42" wide. They also make a 36"

I thought these arms were dead by now. 5" forward? An Easterners idea of how to make mountain parts! Try loading that into a truck or sled deck! Plus, it already proven that there's no need to go further than 3. Hope they aren't thinking of trying to sell these.

So be easy on my my mechanical ignorance...... Does adjusting the caster give you the same performance gain as a +3 set up....... These seem pretty reasonable for a novice....

Caster is not the issue with these sleds. The distribution of weight is. With the arms moving forward it changes the way the sled reacts to differing terrain and allows it to have more control. The biggest area of improvement is the ability to hold a sidehill in rough terrain. While it is an improvement I personally would make it the last item to be changed out having seen what other things can do to help the performance of this sled.
