Another Rockstar collaborative design has arrived! This shift knob has a slightly bolder design than most. This limited edition Rockstar shifter is constructed from three different components: 303 billet stainless steel core, 6061 billet aluminum accents, and a thermoplastic handle insert. The thermoplastic handle helps protect against any extreme hot or cold surface temperatures, so there's no fear of shifting during those months of extreme temperatures. This Rockstar shift knob weighs in at 476 g and comes with four plastic inserts for fitment on a wide variety of vehicles.
