If you're looking to adjust your gearshift reach for a more comfortable driving position, the 12? or 18?inch black shift stick extension offers a simple way to extend your shifter's length. It is designed to thread onto standard shift sticks used in many heavy trucks, providing extra reach for drivers who prefer the lever closer to the seat or want a different feel while shifting. Sold individually as a non?OEM replacement component, the extension should be matched with your existing shifter type and thread size before purchase to ensure proper fitment. A warranty against defects in materials and workmanship is included from the date of purchase.
