Do these knuckles change handling on tarmac?

On smooth surfaces aluminium knuckles reduce unwanted flex, producing a firmer, more predictable steering feel compared with stock plastic parts.

What hardware is needed for installation?

The GPM EF021 uses the existing mounting points and common hardware. Keep original screws and pins, or replace worn fasteners with suitable grade replacements.

Will aluminium knuckles rust?

Aluminium does not rust like steel but surface corrosion can occur; wipe clean after wet runs and inspect for corrosion or damage.
