Product Description

The GrimmSpeed 038007 is a slender Delrin shift knob machined in Minnesota from Duracon thermoplastic - a material chosen for its durability, lightweight properties, and consistent feel across temperature extremes. At just 120g, it's a fraction of the weight of GrimmSpeed's stainless steel shift knobs, resulting in quicker, more effortless shifts without the inertia of a heavier knob. The hybrid shape is designed to feel equally comfortable whether you grip from the top or the side.

The M12x1.25 thread fits 6-speed models directly out of the box, covering a wide range of Subaru WRX, STI, BRZ, Scion FR-S, and Toyota 86 applications. For 5-speed WRX owners, the optional Shift Boot Retainer (p/n 038008) is recommended to prevent the shift boot from drooping after installation. Laser-etched GrimmSpeed logos at the base complete the look with a subtle, clean branded finish.
