Here's s little brain storming idea that has been in my head for a bit now. Through another project, I found that parts from an EPS Grizzly could possibly make a nice swap into a Nytro chassis. The EPS motor assembly is the exact same unit/part number that is used on the Apex and Vector EPS sleds. On the Grizzly it connects directly to the tie rods with a pitman arm, which is quite similar to the Nytro pivot lever to tie rod system.

Grizzly EPS w/ pitman arm.
An additional pitman arm could be mounted to the top motor input shaft, connect the relay rod to that.
Now, this obviously won't be a bolt in, some cutting and brackets fabrication would need to be welded to the subframe….. but let's face it, the subframe needs to come off for proper bracing anyway. I also realize this could be installed high up on the main steering shaft, but that's just too easy, plus weight needs to be kept low.
Other thoughts….
Is there room in the subframe?
The EPS control unit looks just like the snowmobile unit, but has a different part number. It likely has a different assist curve for the Grizzly, and how that will work on a sled is anyone's guess.
These EPS motors and ECUs are plentiful on the used market. The good of that is they relatively inexpensive compared to new parts. The bad is that many ATVs lead a hard life, so the part condition could be suspect.
