  • Reduced shifter lateral play (left/right)
  • Reduced gate width (movement left/right) when selecting gears
  • Stiffer feel when selecting gears
  • Improved precision can reduce missed shifts
  • 6061-T6 Aluminum construction
  • Self-lubricating joints

Narrower Gates, Less Play, Stiffer Feel:

Refining your Civic's shifting system is a great way to add a sporty feel that will put a smile on your face every time you go for a drive. The ACUITY Shifter Rocker Upgrade for the 10th Gen Honda Civic can be appreciated as much during street driving as at the track. Altered geometry reduces the mechanical advantage of the rocker to provide narrower, stiffer gates. Much like how a short throw adapter reduces the distance in the forward and reverse direction while changing gears, this Shifter Rocker Upgrade reduces the distance in the left and right direction while changing gears (such as 2 to 3, 4 to 5, etc). The OEM plastic has been replaced with billet 6061-T6 aluminum construction. This makes for a much stiffer part, meaning less flex when shifting forcefully and better feedback from the transmission during shifts. Additionally, ACUITY's unique joint designs at the main pivot and spherical joint incorporate low-friction, self-lubricating bushings that are designed to reduce friction in the shifter while naturally eliminating any gaps between parts in the joint. This allows the joint to wear-compensate over time, meaning the rocker will age gracefully and provide many years of use, abuse, and happy shifting. Class 10.9 steel hardware and an aluminum bushing replace the factory snap-in feature, further reducing free play. This pairs very well with Acuity's Shifter Base Bushings (1914), Shifter Centering Spring Upgrade (1918), and Short Throw Adapter (1923, coming June 2018).

A packet of silicone grease is included with each kit to help lubricate the o-rings before installation into the shifter. It is not necessary to grease the spherical joint or hinge.

Fitment

  • 2016-2021 Honda Civic (10th Gen, all 6mt)
  • 2017-2021 Honda Civic Si (10th Gen)
  • 2017-2021 Civic Type R (10th Gen)

What to expect


On the Civic Si and Sport models, this Shifter Rocker Upgrade will reduce gate spacing by approximately 11% and will stiffen the lateral action of the shifter. Additionally, stiffness in the left/right motion will increase, feeling more rigid, and free play in the left/right direction will be reduced.

On the Civic Type R, this Shifter Rocker Upgrade will reduce gate spacing by approximately 5% and will stiffen the lateral action of the shifter. Additionally, stiffness in the left/right motion will increase, feeling more rigid, and free play in the left/right direction will be reduced.

Below is an illustration of how the gate spacing changes after installation. Note that the spacing change is exaggerated in the image to make the effect clear.
