The ESCO-T6 is the rebirth of ACUiTYs popular ESCO shape in 6061-T6 aluminum. The ESCO design is quickly becoming the preferred drivers knob due to its carefully-crafted profile. With a 40mm barrel-shaped upper portion, gently domed top, and tapered bottom, the ESCO-T6 fits beautifully in most drivers hands. While spherical knobs have become popular, the truth is they allow a lot of grip variation when changing gears. By forcing a more consistent hand position through its unique shape, the ESCO-T6 helps to train muscle memory, making shifts more consistent. The ESCO-T6 weighs in at approximately 185 grams. The mid-weight is meant to provide enough mass to provide a good shift feel without masking feedback from the gearbox. To compliment the ergonomic shape, each knob is anodized in a durable satin black anodized finish and laser engraved with the 6-Speed gear pattern that is compatible with Honda/Acura 6-speed transmissions. For the best shifting experience, pair your ESCO knob with ACUiTYs other shifting upgrades for your car. Will thread onto all M10x1.5 shifters. Compatible with all Hondas and Acuras with manual transmissions. Important Note About Shift Boot Fitment: On many Hondas and Acuras made after 2010, the shift boot clips to the underside of the shift knob. Older vehicles had a shift boot that just sat near the underside of the knob, but did not mate to it. If your shift boot clips to the underside of your shift knob, you should check to see if it clips to a nut or to the knob itself. If the boot clips to a nut, your boot and nut should work with your new Esco knob as well. If the boot clips to the actual OEM shift knob, however, you will need additional parts to prevent the boot from sagging after installation. We currently provide 3 shift boot collars that can correct this issue. The part #s are 1924-k1 (satin black anodized finish), 1924-k2 (turned stainless steel finish), 1924-k3 (burnt titanium finish).
