The HRD "SPH" Shift Knob in Apex Silver (M10x1.5) begins it's life as a solid billet of 7075-T6 aluminum that is precision machined to our insatiable standards. Featuring a width of 50mm and a height of 68mm, we've designed our "SPH" shift knob to provide the perfect shape for consistent shifts time and time again.
In pursuit of perfection, we spent countless hours adding density to our design without altering the form factor of our "SPH" shift knob. This led us to decide on sculpting a deeply machined inner cavity, featuring a strategically placed stainless-steel slug. Yet even that wasn’t enough. A second cavity was machined to accept a stainless-steel threaded liner, adding both mass and long-term durability for drivers who frequently swap knobs. Together, these components create a sublime, weighted momentum, felt instantly in-hand and echoed in the mechanical honesty of each shift.
It wouldn't be HRD without integrating some of our iconic Titan Frost Ti, so we've machined the lower shift knob trim from the same titanium used on our motorsports-ready chassis, drivetrain, and suspension components. The end result is an object that proves even something as simple as a shift knob can be reimagined when engineered without compromise.
