4MM shock screw mod
Been runnin this for awile now, very tuff Mod. I took it one step further and popped out my lower balls, put them in a vice, held with rubber, and drilled them to 4mm as well.
To prevent bending the rear shock tower and wing mount screws i upgraded all the shock towers screws and the top 2 rear bulkhead screws to 4mm
drilled and tapped the bulkheads front and back and also used 4mm screws on for the shock mounts.
Parts required for mod
3.3mm drill bit (i used 3.5mm)
4mm drill bit
4mm tap
4mm socket head screws as listed below
4mm nylock nuts (x4)
4mm washers
screw sizes used:
shock tower front 4off 4mmx25mm sockethead screws
shock tower rear with losi wing mount 2off 4mmx25mm sockethead screws and 2off 4mmx30mm sockethead screws.
rear bulkhead top with losi wing mount 2off 4mmx20mm sockethead screws
shock mounts 4off 4mmx35mm sockhead screws
First up the 4 different 4mm screw lengths. 20mm, 25mm, 30mm, 35mm
