Arrma RC's
  1. Kraton 6s
Ok, I've got a grinding diff in my Kraton 6sV4, so it's time for diff rebuilds & upgrades.

First off, Can someone please explain the "Limited Slip Diff" in the new EXB. It just looks like a shimmed regular diff?!?!

Should I update to the new Limited Slip, or continue without.

If I continue without, are there better gears than the original ones? I think I've seen people mention Tekno or Mugen.

And, either way I want to upgrade to Alum Diff Cups, so who makes the best ones?

Gpm and integy are trash and m2c is going to release diff cups
But for now I’d go with hot racing
The EXB parts are going to be a while to get

You say Hot Racing over Arrma's Alum one too? What about Hot Racing's 1pc vs 2pc?
 
Here’s my take on the 6s diffs.

Hot Racing AON1101: This unit is made entirely of aluminum and allows us to use the factory metal tombstones. Problem with these unit is that because they are manufactured entirely from aluminum, the steel outdrives eventually wear the cup bore because there is no lubrication (there’s a valid reason why the factory Arrma plastic cups use steel inserts). I run these units and have yet to encounter any issues despite this design flaw. Nicely machined and includes ring gear fasteners when purchased, but no gaskets.

Arrma ARA220050: Arrma’s aluminum/steel modular design. The red body itself is made of aluminum, yet the backplate is made of steel. The downside to this design is that tombstones cannot be used with this setup, so shims must be used or metal planetary gears will eventually wear out the aluminum (some members do not run shims and I do not find this to be a wise IMHO). I run these units as well and prefer them over the HR AON1101 simply because of the metal backplate. Includes (2) diff gaskets and ring gear fasteners.

Mugen MUGE0206 shim kit: I figure I’d mention these as I’ve tried many kinds of shims from many different companies. In the end, these are the only shims I use for shimming internals in all 6s diffs (excluding Nero platforms). Each package includes (6) large shims and (12) small shims... enough to do three complete diffs.

I’ve used GPM and Integy diff cups in the past and cannot recommended them as quality of material is inferior and machining techniques are horrible (I’ve had to lap the ring gear mating surface because of burrs and/or tooling marks). Not worth it just to save a few bucks. Then again, you choose ¯\_(ツ)_/¯

Hope this helps.

I had terrible luck with Arrma aluminum cups set I tried. Holes wouldn't line up no matter what I did. I would get Hot Racing or wait if M2C has some coming.
 
GPM IS NOT JUNK!!! I have their outdrives and they are a ton better than stock. Overpower has a hate on for integy and gpm. He only runs or recommends m2c it's like he's buddies with them. Hot racing is just fancy GPM and Integy at dbl the cost.

Sure, I guess you haven’t had their hardened diff gears shred on the first run then.
 
You will notice with this forum that if it's not M2C it's junk, wich is far from the truth.

Dude every manufactures parts can fail, doesn't mean they are junk. You had bad luck oh well. don't bash a brand. Don't forget Armma is complete junk and you still love and praise them.

For a part to fail, it first has to be installed. Based on my personal experience with GPM, and their lousy reputation, I wouldn’t install their parts if they were given to me free.

If you feel that Arrma is complete junk, just leave the forum. Don’t let the door hit you on the way out.

Armma is complete junk so is Traxxass. Does the chassis bend on a simple jump...yup does the difs blow out after a few runs without aftermarket shims...yup does the radio lag so bad it's unusable and has to be replaced...yup do the stock towers bend like a banana and have to be upgraded...yup does servo chew itself to shreads and have to be replaced with a better one...yup Should I go on or? I have smashed a tree at full speed with my rig with all integy suspension and you know what broke? Armmas crap chassis not my integy stuff. Yes integy and GPM have a bad rep, but what I'm saying is they aren't complete junk I run their stuff with no issues and all the parts so far fit without issue and are completly compatible with the Kraton. And I'm here to stay on the forum for a long long time. Getting lifetime member this week.

If you are willing to spend the lousy 20 bucks the GPM outdrives are great I have them and I have no issues and if the don't work out for you it's not like they are stupid expensive like what the m2c ones will be. I am getting the dif cases next week from GPM to try out see how they are for myself.

You know that all the Aluminum just moved the break to the last thing on the truck that was stock? If you didn’t have all the junk aluminum you md of just broken an a-arm.

This is someone’s truck from just driving around on gpm crap

Dude you can bash them all you want I don't care I like their stuff. You aren't going to change my mind. I have no issues with their stuff. I knew full well that the aluminium doesn't flex and it's not for bashing, hence why I just ordered rpm arms. Now excuse me while I go fix one of armmas crap difs...AGAIN!!

Maybe you wouldn’t have to fix the diff if they weren’t under the stress of the extra weight from the aluminum
 
Thanks for all the tips guys, keep them coming.

As for the M2C vs GPM vs Integy debate. Everyone is entitled to their own opinion and experiences. And i am gathering that knowledge to make my own decisions. If you like or dislike a brand, please don't be afraid to say so, and everyone please stop bashing someone because of their opinion, most are based off of personal experiences.
 
I'm also a huge fan of M2C for many reasons and will buy from Mitch Looper always first if his team offers the product. If he's out of stock, I wait knowing restock will happen soon. The biggest, most popular senders on our forum swear by M2C and contribute their names and time to help grow the brand as part of the bash team. They put their names and reputation on it.
Main reason I'm committed is that M2C is a small US business, taking big risks and sinking big time in design and manufacturing for my favorite RC brand. If Arrma weren't worth the effort, I doubt he'd do it. I also don't feel that the new Arrma EXB parts will damage the M2C brand. IMO, his stuff still appears stronger just viewing the specs and photos and costs are very close.
I finally feel Arrma was respectably fair to these / all small aftermarket CNC upgrade companies and still allowed them room to maintain their loyal customer base. Anodizing them red adds to my assumption of Arrma keeping it fair as most of the guys I see with smartest, big money builds seem to prefer brushed or clean aluminum and will spend for the extra mm of strength. No offense to those who like colors and this is only a hunch.
The Arrma chassis braces I'd try and the plastics from the EXB line so far but if M2C releases outdrives or diff cups I'll be first in line because I know they'll be stellar and a best value for their build durability.

sorry somewhat off topic and long
