The rear shocks need a limiter inside them to limit the travel so that the rear dogbones stay in. You could also put hpi mt2 universals in, they fit fine. I have not had any trouble with my slipper, but have never adjusted it either. I love the truck, it is grat, more fun than a crt.5 when bashing cause it is bigger and has more ground clearance. My 10l is running a 14t pinion gear and the stock spur and it runs cool and gets great runtime with the 4000 4s pack. I also run a pair of 5000 2s packs wired in series, a little heavier but better runtime. I ran my 10l in a crt.5 on 3s 4000 lipo, but it needed 5000 3s to run cooler battery-wise. I much prefer the 10l on 4s, I would run that 12l on 4s, the 4000 pack will be fine.
