Product Description

The GrimmSpeed 038012 Stubby Shift Knob is the compact, wide-bodied version of GrimmSpeed's popular Delrin knob lineup - built for enthusiasts who prefer a shorter throw feel and a meatier grip. At just 105g, it's machined from Delrin/Duracon thermoplastic right in Minnesota, keeping weight minimal while delivering the durability and temperature comfort that makes Delrin a top choice for shift knob material. The hybrid shape handles both overhand and side-grip shifting with ease.

The M12x1.25 thread fits a broad range of manual Subaru, Scion, Toyota, and Ford platforms directly out of the box. For 5-speed Subaru WRX owners, the optional Shift Boot Retainer (p/n 038008) is recommended. Ford Focus RS and S550 Mustang owners will find the same quality and feel as the well-known Subaru versions - threaded and ready to install. Laser-etched GrimmSpeed logos at the base finish the look with a subtle branded touch.
