The WORKS Grab is a CNC machined, full billet 6061 aluminum shift knob. Beautifully blasted and hard anodized, this engineered WORK of art has the right "feel" (50mm/2") and heft (173gr/6.1oz) to provide confident throws. In contrast, the optional factory aluminum ball is a mere 44mm/1.7" in diameter and weighs 111gr/3.9oz. The WORKS Grab screws directly onto the factory lever and sits 6mm/.24" lower than the factory leather knob. The Grab is bead blasted to reduce extreme temperatures associated with aluminum knobs and provides a very tactile feel. Then it is hard anodized gray (Type III) for durability and a perfect interior match. This is a perfect compliment to our WORKS Throw short shifter.
