P/N for SHIMS for Tekno hex upgrade. Based on Bburn's post it sounds like you'd need either (2) of the HPI kits, or possibly (1) Traxxas kit would work with a single 0.5 shim on each side.


HPI Z689 6x8x0.2mm (would need 2 sets)

Traxxas 3981 6x9.5x0.5mm

Traxxas 3982 6x8x0.5mm

There's also these but these are too large OD and would probably rub on the outer race of the bearing. http://www3.towerhobbies.com/cgi-bin...?&I=LXUWK1&P=7

AND AXLE PINS because the AE ones are too long for the tekno hex: (only 4 pins per package, pic is wrong)
