What year and which machine?
I had to look at another post from him, 2015 Ranger XP 900. Webb please put this info in your signature so the members can help you with your question.
The combo will work with forward A arms ( you could probably get by with a 3 inch lift and moving the shocks to the outside and increasing preload, but the forward A arms are the safest bet and will allow more adjustability should you need it).
You may want to contact the seller, it states in the listing that it is NOT for the 900 Ranger (The stud holes on these wheels are 3/8 instead of 12mm, you can see in the listing 3/8 x 24 lug nuts).
I am not sure if Colorado Components has modified their wheels for a universal fit (like Polaris) between the 700/800 Rangers and the 900.
You will not need longer studs.
