The new Snap L-pin is the latest and greatest innovation for your Equal-i-zer® hitch. This new design eliminates the need for a separate clip to keep the L-pin in place. Works like a linch pin where the place. The new design also holds the L-pin slightly above the top of the Equal-i-zer spring arm, which helps reduce hitch noise, especially in slow, tight turns. NOTE: The new hitch noise, especially in slow, tight turns. NOTE: The new Snap L-pin is not compatible with the Equal-i-zer Sway Bracket Jackets.
