Ohhh ok so basically you just lapped the top of the shock body where the cap seats against it? I'll prolly end up building the shocks just like the manual says and see what happens, if I get leakage from that area I'll give your trick a go, along with the black grease on the threads. Do you think maybe the rear diff issue has something to do with possible differences between the two diff cases? Tolerance wise? The front and rear diff cases are interchangable, no? Funny that the rear diff would wear different from the front; all things being equal. Think I'll marinate the diffs in diff oil (and worcester sauce) before assembly.
Thanks for the insight, I'm still fairly new to this hobby and I'll take all the help I can get!

Cutting the top plate is due to the added thickness of the front diff case where the tower attaches.

Improved 35T diff gears V2 - they have symbol 35 on the back of the gear. Replace both front and rear. The new gear reduces play of the internal satellite gears inside the diff to reduce the risk of damage to the satellite gears.
The reason is simply that. With the new big gears the small gears move closer together and have less play = less breakages.

Looking everywhere and cannot find these pins. Amain, stormer and nexus are all out of stock. I cant even find them on fleabay. Are there any reputable euro shops that ship to US that might have this part?
Edit: just found them at apex models in UK. I hope they are reputable. If not its only a $22 PP claim. Fingers crossed.

Apex Models are well known in Europe so you don't have to worry.

Tech Apprentice
In 1,5 day (with a working day in bewteen) I built the XB4. Nice car to build. The build had to go quick because tomorrow is a race day (Usually I only race 1/8 nitro)
I've drove the car today and recieved some custom made parts for the XB4.
a new topdeck, front brace and 2 shocktowers out of some compositie material.
Topdeck installed. This will stop bending the chassis forward and has a big influence on the flex of the chassis.
Installation of the front brace:
Shocktowers:
I tested the Xray stock and adapted the setup and installed the custom parts just now. The result has to be tested in the race
.
But pinion 19T on a hacker 5.5 is already fast. But I think for outside racing it needs to be geared a bit higher (or enable boost).

Does anyone here run 17.5 blinky on their XB4?
I am wondering what pinion I should try for stock on a outside clay track, medium sized...
