WP Preload Adjusting Collars -50mm WP shocks

These Preload Adjusting Nuts are precision machined to replace the plastic Adjuster that is always stuck in place and impossible to turn.  The adjuster nut is machined from Aluminum and anodized while the Upper locking nut is machined from steel and plated for corrosion resistance.  The steel locking nut has a wide contact area so that damage from hitting with punches, etc does not cause distorion of the nut.
