This Is A Stopper Pin Installed On The Steering Block Of The YD-2 Series To Regulate The Steering Angle. The Shaft Diameter Is 4mm And It Is Made Of Steel.
When Using The Standard Set Screw Of The Kit, You May Feel A Drag On The Thread When The Suspension Operates At Full Steering Angle, But By Replacing It With This Part, There Will Be No Impact On The Stroke.
