I have had my 03' AC 400 auto since November. I plow with it and have been dragging wood with it. Have been extremely happy so far with no troubles. The machine will do more than I ever thought it would.

 

...And one more thing I like about our 400's. They're a LOT better on gas than the cool but thirsty 650's and other brands's 700's. I really have no need to do 60-70 mph. We normally cruise (on a 'good' road) around 15-20 mph, cuz if we can DO 40 or so, we're on the wrong raod!

 

Hi
I have a 03 400i with 3500 miles on it original tire until this week end ,I just got 26 mud lites.
I have a K&N, tran mod, muf mod. this is working great. I will be doing some maint on it new spark, oil & filter. Did a raly over the week end mud mud & mud . The fullest I have ever seen it, I still had the slicks on it but didn't get stuck once and other then what I think is a new plug worked good.

 

My ride is below, my wife and I put on about 20 miles last weekend, not too bad considering we still have 6+feet of snow on the ground! I would like to get some new tires too, but will wait a year or so.

 

Tires will make a big difference in the handling, the stockers ( I assume they're Dunlops) are garbage, ANY tire will perform better. You'll also find they ride a little better with the shock dialed up on or near the highest settings.

 

I started out with my springs dialed in half way. It seemed to ride pretty hard. So I took them all the way down and it seemed to ride better at least for break-in period. Still only 120 miles on it so springs are probably not quite broken in yet. I'm curious about what tires anyone else has tried. Bigger size and or more aggressive tread than stock. So far stock tires aren't bad but I have the feeling they wont last that long.

 

Hey Treehead,

I adjusted our shocks down the the 'wimpiest' setting too and actually LIKE the feel of them there. Rides better. Then when I checked to see how much air I had in the tires (the dealer told me they were about 5 lbs) , I found they had between eight and ten pounds - GASP! So I let them down to about 6-7, and may drop them to 5 like everone seems to suggest. Rides MUCH better now - duh.

Ours came with Carlisle radials and they seem to do all right.

 

Howdy ya'all
I have been looking to get a little more power out of my 2003 400 4x4. Does anybody know of a aftermarket exhaust for the 400? I have just put 26" 589's front and rear, warn winch, you name it, it has it, but we need more power. I LOVE THE QUAD....Thanks

 

MrTommy is right, mine has the Carlisle Badlands XTR radials, not the Dunlops.
