Looking to add stiffer springs to my xp900 for the Boss v plow. Seems the brutus has springs available that are 700's.

anybody ever look into it?

Can you post a link, where you are looking at this information.

I find it hard to believe it is a 700lb spring for a stock machine, but if your plow is big/heavy you might want one that big stout :)

i'm guessing it's for the Brutus with the forks and bucket.

Looking at the information, you are correct, but the listing for the springs, also on the Polaris website, are 250 and 900. The 900 are used for the bucket/fork attachment. The shock part numbers are also different, you will need to do a parts comparison to see if it will work.

when I clicked on the 900's on fixmytoys it showed up as 700's in the check out so I just went with the lowest numbers to be safe. My friend that has a Brutus is going to take some pictures of his bike for me, but he says his Brutus is the same frame as the xp900.

I did not click on them, I just read the text.
The Brutus mostly has the same frame as the 900.
Looking at the information, the Brutus springs will fit your ranger, the only thing different is the front shock itself. The only thing that may be different on the shock, could be shock rod diameter or valving, the shock body and spring retainers are the same, as well as the length.
The (700/900) spring rate sounds like a lot, but may be just the correct amount for your plow. Some members have used the crew front springs, they have a spring rate of 280, and members have reported some sagging with them. The rear crew springs could be used, they are 305#, but if remember correctly they are shorter than the front springs, so you may need a spring spacer.
If you decide and do this, please post back.

I just went to the Polaris site and saw that it's a 900# spring. the plow is 400 lbs so it might be just fine.

You may already know this, on the 900# lb spring, basically it takes 900lbs to compress the spring 1 inch, 1800lbs to compress the spring 2 inches etc. it looks to be a progressive rate spring instead of linear, which will help soften the ride a little.
Its definitely a lot of tension/resistance, so I will be curious how it works out for you.

Side Note: You may want to consider purchasing a complete assembly as opposed to just changing the springs when you need to (will be easier and safer). You will definitely need a spring compressor for those springs.
I use a ratchet strap to change mine, and the #305's put up a good fight, I would definitely not try that with the 900# springs.

I'm going to bump this old thread since winter is coming around again, and I have some info to add.

The Brutus HD (with the hydraulic lift arm on the front) does use an extremely stiff spring on the front. The installed spring height is the same as a 900, but the shocks are shorter. You do not want to put these springs on a Ranger unless you want a seriously rough ride. Even with all the added weight of the Brutus and the adjusters on the lowest setting, they ride fully extended. It takes a serious amount of weight to get them to move even slightly. You won't get them to move by pushing down on the front end. I put Ranger 900 shocks and springs on my Brutus. The Ranger shocks are roughly 2" longer overall, but the ride height is the same. I plan to get a plow and I'd like to get some heavier springs, but there's no way I'm going back to the stock Brutus HD springs. I think I'm going to try the Brutus rear springs up front. Here's a list of part numbers and weights from my notes.

Brutus HD front 900#
Brutus Base front 250#
Brutus rear 7043750-458 350#
Ranger 900 front 7043756-458 #225
Ranger 900 rear 7043754-458 240#
Ranger 900 rear 7043937-458 225#
Ranger 900 crew front 7044020-458 190-280#
Ranger 900 crew rear 7044019-458 260-305#

King shocks has a nice variety of different rate springs.

Another one for your list, crew rear springs 260-305#

Subscribed, just in case.

The pic in post #11, serious size difference in those 2 springs, visually. The girth on the lower spring is stout for sure. Is that the Brutus front spring?

That is a Ranger 900 shock/spring in the upper part of the picture and a Brutus HD on bottom.
