Show original supplier description
The Acuity Shift Boot Collar Upgrade offers a clean solution for sagging or broken plastic shift boot collars, ensuring a perfect fit and finish between the shift boot and shift knob, regardless of knob style. Constructed from 6061 billet aluminum with a satin black anodized finish, this collar is designed to replace the OEM plastic ring and work with virtually any M10x1.5 shift knob. This upgrade includes two types of stainless steel binding nuts: one for flat-bottomed knobs and another for boss-bottomed knobs. The collar itself is reversible and can be flipped to accommodate different shift knob base diameters, whether they are narrow (22mm lower diameter) or wide (28mm lower diameter). This design prevents the common issue of breaking the OEM plastic ring when removing a shift knob. The Acuity Shift Boot Collar Upgrade is compatible with a wide range of Honda and Acura manual transmission vehicles, including specific generations of the Civic, Accord, S2000, RSX, TSX, CR-V, Element, and Integra. It also fits most Honda M10x1.5 shifters, though the provided list represents confirmed fitments. The kit includes the shift boot collar, two binding nuts, and small cable ties for installation.
