You can do the cross checking from this list as to where you want to take a chance on the Quad Logic kit working or not.Polaris Sportsman Ranger Front Differential Rebuild Kit - ALUMINUM CAGE | eBay

 

OPT
That's the issue im having everthing that it fits is on the list exept the ATP maybe cause it is a CROSSBREED?????
Lists that it fits all 04 models you have listed OPT just a little hesitant to pull trigger think I am overthinking to much
Also how hard to get large bearing off ring gear only enough room to get small screwdriver do I need to get a bearing separator and puller from harbor freight looks like it would be big help for front input pinion also

 

Possible they didn't list the Atp because not too many units were sold. My two cents is that Polaris wouldn't go to the trouble of making a different front diff for an Atp when the main difference between it and a Sportsman 500 was just the dump bed on the same year model. Bearing separators are a good tool to keep in the tool box. They always come in handy in pulling or at least moving tight fitting bearings out to where they then can be easily removed.

 

Thanks OPT pinion bearing and large carrier bearing on hard going to borrow tools to get off easier did some homework part# for part# all the same, took a chance and ordered last nite got a message from them today and they said it will fit just not enough info on that model interested in getting all back together bought knowing front end was inoperable will let know how things go

 

I figured I would close this one out and say QUAD-LOGIC Kit 100-2082 worked out fine! 4x4 on the ATP works well all parts worked out Even that big ginormous bearing was right came with 2 different sizes of seals and pinion bushings just had to match to my old ones VERY NICE ALL INCLUSIVE KIT hopefully helps someone else out TOO.

 

Glad it worked out for you. This kit even shows to fit the 600,700 and 800 models also. Most of the individual aluminum cages listed on Amazon or ebay would fit all centralized diff models also.Guess it's just that they seemed to forget the Atp and just lumped it in with the Sportsman 500.
