From Exotek Racing:
100% machined 7075 alloy steering rack and crank set for Kyosho ZX-6 and ZX-6.6.
Improved design, based on our very successful D413 rack design, removes all of the plastic parts and bushings and adds 4 ball bearings (3X6mm) and 2 crush shims for the longest wearing, smoothest and most precise operation.
Includes 2 steel ti-ni coated bearing screws, 4 ball bearings, 2 crush shims, 2 alloy cranks, alloy steering rack and 2 alloy steering post spacers. Uses the stock ZX-6.6 posts and post bearings.
Extra heavy duty design that matches the stock geometry and also allows mounting of the servo on either side of the chassis.
