Tested Z-Broz Spring Kit/ 2013 Pro

W

winter

Well-known member
I used to build IQRs and XPRS racers into Mt. sleds.
My goal with those sleds was getting them set-up to handle really crappy snow conditions in very technical back country riding areas.
This is also my goal for the Pro chassis.
I am starting with the least expensive options then going on to more elaborate set-ups.
Last Friday I installed a Z-Broz spring kit on a 2013 600 Pro and took it up for a 4 hr test ride along with a stock 2013 600 Pro.
I switched back and forth between the two sleds through-out the ride.
Snow Conditions-- 6-8" new light snow over set-up hard pack.

1.Big improvement in the washboard trail heading to the high country.
2.Weight shift and set up between powder turns much smoother.
3 Required much less effort when holding a side hill in the hard set-up areas.
4 Down hill u-turns took much less effort, especially where the snow was uneven.
5.Rode single track home with big whoops, way more fun and less harsh landing then stock sled.
All in all it was a very good change, the spring kit made a really good sled feel much more alive and the cost was minimal, the sled no longer felt like a hay wagon.
This is the first and only spring kit I have tested, the test was a back to back test with an identical 600 pro in stock form.

I will be building one with a complete Timbersled and Z broz suspension next.
Will let you know how it goes.
 
Winter, did you revalve as well or just swap the springs?


I did not revalve, though it would help on rebound for sure, I was trying to keep this as easy and inexpensive as possible.
I would definetly recommend doing this for lighter riders who are having trouble getting the sled to hold a side hill on set-up snow, ask for the lighter spring kit, if you are light.

Thanks for the replies.
Have fun.
 
Shannon...Great write up ... thank you for sharing with our readers.

What were the Springs (main and Tenders), and crossovers that you used?
Rates/lenghts?

Photos?

Mountainhorse,

I believe that he is talking about the ZBroz Dual Rate Spring Kit. Here is a picture of that kit.

So Shannon you think I should stay away from that spring setup since Iam a bigger guy? And thanks for the awesome sled:face-icon-small-hap

If you choose the spring kit route, call z-broz directly and let them know your riding weight, they will get the correct set-up.
I said I wanted a set up for a 140-150lb rider.
Have fun on that sled.

This would be good info.


I just contacted Nate at Z-broz and asked him for a complete spring kit for a Pro- for a 140-150lb rider. Photos are on the Z-broz site, let them know your rider weight.
I can take photos next time I have the sled out.
I will look for a stock no. if you are trying to match this kit.
 
Was this "test" with only the front dual rate spring kit or did you also swap the rear springs? Sorry if I missed it.

This was the complete kit front and rear, I felt the front shock spring (skid) to be too stiff.

do you think its worth doing the ski shock springs alone ?
(i would like to up grade shocks but having a hard time affording them)
i already have a holtz fox kit in the skid
thanks

yes, the front feels much more alive, looks like Holtz is doing a shock revalve, may be an option I will look at.
Have fun
 
Did you use the stock spring pre loads when setting up the sled?
