I run the graphite composite blend through out the whole drive train and love it.
They are super smooth, insanely quiet and have been very durable. Thus using the center gear diff and not trying to power hop over lane tubes/rails I have had zero issues with any of the graphite/composites. I also am running a 6.5 thus having some extra jack has not overwhelmed the gears in anyway.
Make sure your drive pinion and crown gears stay lubed via graphite grease. One can use a plethora of different lubricting products. I have had very good results with the graphite grease. Personally I like Eureka pro lube as I believe it works better and definetly makes an already quiet drive tran even quieter.

Another thing, I've done a jig and CNC program to modify slipper 72t spur gears to fit the centre diff instead, is this something that people would be interested in?
It would be great if you all designed and produced a weighted rear skid plate for the XB4. Thus very sleek with the end point wrapping up over the rr hanger. Basically a weighted rear skid plate rear bumper combo in one. Exotek makes one for the Durango wheeler for reference.
I know a lot of XB4 enthusiasts would definetly purchase this type of aftermarket part if It were available even more so if produced by Bugle Boy.

Best,

Hey guys, I have 12mm hex's up front and would like to run silver wheels for carpet tires since my 2wd's wheels are silver. Does anyone know if someone makes a set of silver 4WD front wheels with a 12mm hex?

I've been running 13.5 in mine for a while now with the center gear diff I'm running 78 27 with a fan on my motor. If you still have the slipper I was running 75 26. You will need a fan the motors work alittle harder in wheeler. With. Fan my motor comes off 125 degrees or so without 170degrees easy if not sometimes higher.

Hello everyone, I need some set up help.

I run on a fairly large, hard packed track, we run Dirt Webs and Bar Codes in green and black compounds. It goes from damp to dry, but has been well swept this year, so little to no dust. It has more traction as it dries. I have no rear traction. Every time I want to lay down the power the rear end wants to step out on me. I have to baby the throttle and watch others pull away. My tires are new.

I am running a 2015 in shorty config. With a center diff (500K) set up the following:

Front
8K diff
1.6x2 hole pistons
550cst
2 dot springs
No sway bar
Shock mounted on the Middle hole tower, outer hole on arm
Bottom hole camber mount on tower, 3mm on 9deg. Hub

Rear
5K diff
1.7x2 hole pistons
400cst
1 dot springs
No sway bar
Shock mounted middle hole on tower, inside on arm
Camber mounted top hole on tower, middle hole on hub.

Gearing is 81/19 with a 6.5T. EPA -30% for both throttle and steering.

I put it on a 4 post scale and it was actually very well balanced with 25g behind the motor. However the weight distribution front to rear was only 45/55%, front to rear.

Does anyone know if Tyler Vik's Tacoma would work on the newer '15 spec? I am open to trying pretty much anything.

Thanks in advance.

Have you tried 8 front and rear?
What about a lower center fluid?
Sway bars?
Anti Squat and roll center change might help too.

Go to 7 and 3 on the diffs. Get rid of the shorty and put in saddles. Lower rear camber link to bottom hole on the tower

Don't change ANYTHING except put 60k in the center diff and report back.

Should be getting my XB4 in today, picked up a used 14 on here. I'm pretty pumped, been wanting one of these for a while and this class has really been growing at my local track.
