After installing the Moose lift kit I saw posts on another forum about lift modifications putting excess strain on the axles. My mod provided about 1" of lift. (makes a difference on an older model quad like mine) I have never seen that concern expressed here.

Is this a concern? I weigh about 140 lbs and usually carry under 100 lbs of gear. My trail is very rocky but I go pretty slow, under 5 MPH. the lift is not worth it to me to risk a costly repair.

Thanks,

I've have a Moose lift kit on my 2001 AC 250, for almost 2 years now. No problems at all and the wife and I rode 2 up for almost 6 months. Now she ride the 250 and I ride the 400 and she weighs as much as you do. Oh yeah, I weight more than you and you gear put together and I also usually tote around 75 to 150 lbs of gear (nothing like being prepared for any and everything). It's the high horsepower guys that tear things up and the lift kits are and easy thing to blame rather than their over use of the throttle. I would suspect that you will have no problems with it.

 

Thanks Bear,
I know you have that mod, that's where I got the idea to do it.

Yeah and it is still on the 250 and the only drive train trouble has been 2 torn boots and a bad front wheel bearing (water in it screwed it up).

 

I do remember back a couple of years ago, several people reporting broken axles on IRS Cats with lift kits installed.

Trouble with the the IRS Cats is that they're already jacked up from the factory, that's how they got the high ground clearance. Raising them even more really bends the U joints at a serious angle. I don't think the live axle or ACT cats had this issue.

 

I am unaware of an Arctic Cat that uses U-joints. I thought they all had CV (Constant Velocity) joints which handle extreme angles better as long as you keep the power to a reasonable level and the 250 and 300 meet that requirement. The guys having trouble mostly were in the 500 and up class. On the newer machine, the 400 and 500 AC's now have the same CV joints and axles as the 650's. Shouldn't really be able to hurt them. The only problem with some of the newer axles has been with a hardening and over torque proble from the factory.

 

I have a 01 500 with 26/10/12 and 26/12/12 mudlites and moose lift on for 800 miles and no problemes. I did have to replace the front wheel bearings at 2100 miles,I don't think the lift had any thing to do with it ,maybe the tires? Or maybe just normal wear.
