I had a few requests to do a write up on the snopro steering we did on an M series build a few years back. Basically, you guys can use all the steering parts from the 2006-2007 snopro on your sled and it will bolt up just fine, with the exception of making a bracket from the gas tank mounts to the steering post adjuster. We only used four stock parts from the 2006-2007snopro and machined/fabbed up the rest, which saved a lot of money.
The part numbers we did use are as follows:
0607-844
1705-174
0605-877
1705-143
1705-142
The sno pro steering uses two bell cranks as opposed to one like on the M series. We used two stock bell cranks from an M and machined the splines in order to make the bolts work correctly on them since we had changed the angle the bell crank points. The bell cranks are also tied together beneath the bulkhead with an aluminum bar, as shown in tie rod assembly picture. This is also used on an 09+ M series, which we started with so we did not have to purchase this part. The bell cranks are tied together using 1705-142 143 on top. Everything is pretty straight forward from the parts breakdowns. The snopro bell cranks have small bearings in them that the bolt runs through. We didn’t do this way, we just put the bolts right through the stock bell cranks and we haven’t had any problems.
There are no chassis modifications done to accept this steering on an M, but the hood does need to be cut, and the gauge needs to be relocated to either side of the existing gauge opening. The ECU also needs to be moved to either side of the belly pans to clear for the steering plates. The pictures below will show what I am talking about.
The bracket from the gas tank bolts to the steering post adjuster is made from light square tubing. We have two angled pieces of tubing welded to a straight piece of tubing, which has a rectangle cut out in order to access the nuts on the gas tank. The steering post adjuster is attached to this square tubing, and the supports that run down to the front of the bulkhead are attached to the steering post adjuster. We have since changed the design a little bit due to our support tubes cracking, but that was a design flaw on our part. We now have a support connect the two down tubes which takes away the flex it had before.
If you guys have any questions feel free to ask, I would be glad to answer them. I tried to explain it the best I could, but I’m sure some of it may sound confusing! We have 2 years on this mod and it has been great, it gets you further forward on the sled and side hilling is not an issue with the different steering plane.
