CoryMJ89 Posted February 20, 2013 Share Posted February 20, 2013 Found a set of motive gear performance gears has anyone used them or quality? Link to comment Share on other sites More sharing options...
zackcj7 Posted February 20, 2013 Share Posted February 20, 2013 If I remember correctly i'm running Motive gears in my TJ. They seem to be holding up well. Link to comment Share on other sites More sharing options...
mnkyboy Posted February 20, 2013 Share Posted February 20, 2013 I put a set in an LJ Rubicon for Darren ( formerly known as goblazers_6) , the gears were fine but I didnt care for thier install kits. They didnt seem to have enough different shims to make the combination I needed, lucky for me I have a bunch of leftover shim sets at the shop so it wasnt an issue. Also IIRC they supplied Koyo bearings rather then Timken bearings. But for the money they seemed like a good deal, he has been driving and wheeling with them for about a year now with no issues.

Alexia Posted February 20, 2013 Share Posted February 20, 2013 They have a good enough reputation. The thing about gears is that, according to research down by the owner of Northridge4x4, there are only about three foundries that make the gear seats. Then a bunch of companies that resell them. Any with cosmetic flaws get sold as the cheap brands and the perfect sets get sold as the expensive brands. With that said, I am installing two sets right now.

mnkyboy Posted February 20, 2013 Share Posted February 20, 2013 Really proper gear set up is more imortant then the brand of the gears. I have US standard gear 4.88s in the MJ which is about a cheap as they come and they have been fine. Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 20, 2013 Author Share Posted February 20, 2013 Yeah we'll I found for my 8.8 brand new 4.56 motive gear to run with my 37s just neve heard if it Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 20, 2013 Author Share Posted February 20, 2013 Is 4.56 to tall of a gear ratio do u guys think or should I just go to 4.88? With my soon to be 37s Link to comment Share on other sites More sharing options...

CoryMJ89 Posted February 20, 2013 Author Share Posted February 20, 2013 Dana 30 chromoloys eventually maybe w truss Link to comment Share on other sites More sharing options...
mnkyboy Posted February 20, 2013 Share Posted February 20, 2013 I would rethink the 37s. Remember as you beef up your axle you move the weak link inward, the D30 ring and pinion will not like 37s. Link to comment Share on other sites More sharing options...
Alexia Posted February 20, 2013 Share Posted February 20, 2013 Is 4.56 to tall of a gear ratio do u guys think or should I just go to 4.88? With my soon to be 37s 4.88 minimum for 37" tires. I would recommend 5.13, but the D30 will not support it. Link to comment Share on other sites More sharing options...
Bornindesert Posted February 20, 2013 Share Posted February 20, 2013 I put a set in an LJ Rubicon for Darren ( formerly known as goblazers_6) , the gears were fine but I didnt care for thier install kits.

I found Koyo's installed from the factory on my 1988 HP D30, believe they were used when Dana orginally built the axles for AMC. The DANA OEM set up kits I bought came with plenty of shims, and Timken bearings. I didn't like the sharper radius on the back side of the Timken race. When you shim the carrier for final assy and pre-load, they would hang up on the corner edge and remove metal if you were not real careful. The Koyo's had a nice radius, would slip right in with a couple hits of the mallet. Link to comment Share on other sites More sharing options...
mnkyboy Posted February 20, 2013 Share Posted February 20, 2013 I didnt have any issues with the Koyo bearings, I just threw that out there since some guys have a preference. Ive known a lot of guys who like Timken and nothing else. Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 20, 2013 Author Share Posted February 20, 2013 How much do shims usually run? Link to comment Share on other sites More sharing options...
mnkyboy Posted February 21, 2013 Share Posted February 21, 2013 Depends on if you need a shim kit or a full install kit. $40-$150 depending on brand. I'm gonna guess that you have never set up gears. I hope you know someone who has that can help you. Link to comment Share on other sites More sharing options...
MtnClimber Posted February 21, 2013 Share Posted February 21, 2013 I run 4.56 Motive gears in my Aussied 8.25 & HP30, both from a 98 XJ installed in my 00 XJ. 33x10.5 KM2's. Lotta street time, overloaded camping trips, and hardcore rocks. Absolutely no issues whatsoever. Just my .o2c Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 21, 2013 Author Share Posted February 21, 2013 Yeah I know a guy who does se them up so think 4.88 with the 37s bc 4.56 might not be enough even tho there not muchof a difference Link to comment Share on other sites More sharing options...
mnkyboy Posted February 21, 2013 Share Posted February 21, 2013 Why 37s? A 37" tire is just way too much for a D30. Unless your building a mall crawler your asking for problems. Even if you build the 30 I wouldnt go over a 35" tire which would also be better suited for 4.88s Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 21, 2013 Author Share Posted February 21, 2013 Haven't a had any probs so far or other buddy's runnin that big or bigger like 39.5 iroks seems to hold up so far and break a shaft got extras lol Link to comment Share on other sites More sharing options...
mvusse Posted February 21, 2013 Share Posted February 21, 2013 You obviously wheel different terrain out west, because with 35 (and the stock 3.55 gears) I have broke probably well over 20 shafts and u joints, broke a supposedly pretty much unbreakable locker twice and grenaded two diffs. Oh, and ripped off a few control arm mounts as well. Link to comment Share on other sites More sharing options...
mnkyboy Posted February 21, 2013 Share Posted February 21, 2013 Doesnt have anything to do with the terrain here, I don't know were he wheels but its probably not any of our OHV areas. Another thing to keep in mind, he has also been talking on another thread about getting a front locker. Talk about D30 time bomb. Link to comment Share on other sites More sharing options...

Also keep in mind that the center section is the weakest link in your axle so if you start upgrading shafts and such your going to start stripping out ring gears. If your set on 37s I would atleast go to a D44, it can be built to handle 37s and can accept a more suitable gear ratio. Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 21, 2013 Author Share Posted February 21, 2013 I don't pin it to win it lol shouldn't snap a shafts unless are spinning tire and catch something solid then something will break but that not wheelin in my opinion Link to comment Share on other sites More sharing options...
CoryMJ89 Posted February 21, 2013 Author Share Posted February 21, 2013 Yeah I will eventually What do u guys think about USA standard gears? Link to comment Share on other sites More sharing options...
mnkyboy Posted February 21, 2013 Share Posted February 21, 2013 Getting a tire bound up can break a shaft too.and you can't say you won't throttle into it,some situations require some wheel speed. Your gonna have to crawl as much as possible and stay out of the rocks, my concern is a 4.88 isnt gonna be deep enough to do that without a 4.1:1 or a crawl box. I have us standard gears 4.88s in my MJ, so far they have been fine. Check this place, they had the best prices when I did mine. http://www.ronsmachiningservice.net/ This place is good to, they carry motive. http://www.rwkhaussupply.com/ Link to comment Share on other sites More sharing options...
