At the top of the XB4 page you can click on all of the previous years and see what their specifications were. All the new stuff for that particular year will have a big "NEW" by it.

So recently my 16 car has been roaching pinion gears in the rear gear box. At first I thought here we go again, like the dastardly 14 car, I need to go in and shim up the difs for a tighter mesh. Which I did. However last night only a week later my rear trans has started to sound ratchety and make the noise it does when it's blown a pinion gear. I remember the 14 car had issues with the slipper being too tight. I decided to run the slipper on the 16 car since it has been redesigned and I've liked the feel, I run it as loose as you possibly can so I'm apt to rule that out as a culprit unless it just doesn't matter what it's set at and it sends too much power to the rear.
I'm super frustrated. This is the third gear it's cooked. Never had an issue with the front gear box only rear and I'll add my 15 car with the center dif has never roached a gear.
Suggestions?

I'm been dying to get a XB4. Do you think they'll drop the price on the '15? Or should I just spring for the '16? Seems like they update all their cars every year.

You can try those but i didnt like them on high or medium bite tracks. I like the avid 2+2 pistons. 1.1x1.5 and 1.1x1.6 with 32.5 & 37.5.
you might what to try those if you dont like the 1.6 and 1.7.
also I am running medium plastics all around, center diff 8k,200k,5k, and the Steering X brace. Also have the aluminium rear hubs and steering rack.
here is a alink to my setup for a tight track with a couple 180 degree turns

+1 on Randy's piston suggestion. I myself currently am using 1+1 X 1.5 front 1 + 1 X 1.6 rear with 37.5 to 40 front and 32.5 rear.
5k front 500k center and 3k rear(actually more like 2800) using all medium flex chassis brace and side rails. X brace aluminum Ackerman/steering, alu 9 degree casters.

Hey guys...stupid question...almost done with my 16xb4 and went to mount the servo (savox1258tg) and its about 3mm to narrow. Do you have to use certain servos in these cars or what am I missing. Thanks for the help.
I think X-ray just makes their servo mounts wide as I have had the same issue. I just use washers and haven't had a problem.
Tech Regular
I just put washers on the screws that hold the servo to the servo mounts. I had to kind of push the bottoms out a bit to hit the holes but it wasn't that bad. Thought it was a bit strange since servos have been standard for a very long time.
Tech Regular
Gotcha. Yes very strange. I may look at building custom mounts. I wonder if the floating servo mount has this issue.
No the floating servo mount works perfect, thus no issues.

I picked up a used XB4 '15 that was in excellent condition about 5 months ago. I like the buggy, it is super easy to work on and very high quality. However, I have had to replace the rear and now front steel bevel drive gears (XRA365134). I read the forums and it appears these gears tend to be a problem for other XB4 owners. The biggest concern I have now is the gear is out of stock at RCAmerica, Amain and Absolute Hobbyz so I might have to shelf my buggy until the part becomes available again.
Has anyone found a way to prevent these gears from stripping? I read the XB4 '16 has reinforced differential cases, for people that own the XB4 '16 has this helped resolve the issue? I was thinking about possibly upgrading but I am concerned about these gears and the lack of availability in United States. If the new changes on the XB4 '16 helped this issue then I might pick up a new one, if not I might explore some other options.
So any feedback from XB4 '16 owners about these gears would be great
Thanks,

A lot has to do with your slipper setting. Also don't hope lane tubes. Center gear diff will help prevent issues if your diff oil is under 300k. I never had an issue with my 15 and I ran full graphite/comp blend gears (v2 35tcrown gear and 14t drive gear)
