The installation of a CKRC "rock-it" chassis on a berg is very similar to our rockstar installation on a berg. This is a link to the build thread for the rockstar, but requires no trimming of the skidplate.

A.) Installation of our adjustable shock ears is very straight forward. Our Berg competition crawler kit uses (4) 120mm shocks shortened to 113mm, center to center. The picture below shows the starting point for chassis tuning.
B.) The (8) 3x10mm screws included in the kit attach the shock ears to the chassis sides. Start by installing the shock ears center pivot hole threw the chassis and into the 45mm post. There are (4) 3mm holes in the chassis side plates for up and down adjustment. Our recommendation is to use the 3rd hole down from the top for 113mm shocks. Finish by mounting the shock in the furthest hole out towards the axles on top.
C.) The new delrin skid has a 3mm hole in the center. Most customer make a aluminum or lexan esc plate and bolt it in there.
