This is a replacement for the sometimes hard to find crp 1604 heavy duty steering kit for grasshopper  and hornet

This kit replaces the steering links with threded ball swivel ends and thicker threaded rods, eliminating the thin wire that tamiya supplied that bends easily.

You will need to drill the spindle arm holes with #43 drill or tap to 2-56. Install screws and nuts using medium strength liquid thread lock.
