Xtra Speed Diff Lock SCX-10 Axles - Update 

+custom fast rc Thanks! I bought mine off of ebay.

No, not at all. These axles are among the worst I own & would require a ton of work to make them what you want. I think you would be better off buying the axles from a Traxxas TRX4. You’ll probably need a counter rotation transfer case as well.

@@Rcculture Thanks for the advice.

@@Rcculture I've been having a good look at the axles, the issue is that I can't get a counter rotation transfer case to fit my truck. I may have an idea though, if it works out I'll send you an email. Thanks for the help.

No, I don’t believe they are made anymore and honestly I can’t recommend anyone buying them.

I think it depends on your expectations. As the first 1:10 scale axles with an optional servo actuated diff lock I had to try them. If you watched the first video I said from the start that they aren't Vanquish quality, but then again not much is. I may have a "kit" available soon to correct the problems that my axles have if anyone else needs it, hopefully XtraSpeed will address the machining & polishing tolerances and quality control issues soon. I think if you are willing to do some minor mods they can be a very interesting option and could add a very scale experience to your adventures.

+RCCulture you are well spoken and certainly you can fix the problem. I wonder though, what purpose an open diff on a crawler could have? I drive very slowly with mine and with most off-road surfaces a locked axle steers well. The slop and the improper length of the steering rod combined with the questionable need for open diffs combine in my mind as a waste of money. The diffs on a Traxxas Summit are pretty cool and there is a reason to want open diffs in that vehicle.

+Stricklinator Thank you. I think it depends on your definition of "crawler". From a 1:1 scale perspective these would be like adding an ARB air diff locker in your showroom stock vehicle. From a 1:10 scale perspective I think these would be mostly for someone who wants to emulate that as close as possible. So it would be people who do a lot of trailing with some rock crawling or someone that wants the ultimate scale SORRCA Class 1 rig. There is also the scale novelty factor of being able to independently lock up the diffs. I agree that these wouldn't be very useful for someone that does almost nothing but dedicated rock crawling such as a Class 3 rig like a rock buggy.
