This kit is designed to turn your OEM shifter into a finely tuned piece of machinery. The short throw adapter and rocker upgrade help to reduce both gear throw (forward/back motion) and gate spacing (left/right motion) while stiffening up gear engagement and lateral feel. The shift cable bushings and shifter base bushings help to remove unwanted compliance from OEM rubber bushings to help remove flex while improving tactile response during hard shifts. The upgraded centering spring helps to quicken centering action for a snappier feel while removing unwanted lateral play while in gear or in neutral. Add the interior panel removal tools as affordable protection against damaging interior panels during installation.

Note that some vehicle trims will require the use of one of our 1924 shift boot collars to hold the shift boot up when using an aftermarket knob like our ESCO-T6, ESCO Insulated, or ESCO-Ti designs. Please refer to the "More About This Kit" section for recommendations regarding shift knob and shift boot collar pairings by application.

Shifter Cable Bushing Upgrade

Bad news: your OEM bushings suck

Honda intentionally makes their rubber shifter cable bushings very compliant in an effort to give the car a more tame feel. For many drivers, that's ideal. Unfortunately, this disconnects the driver from feeling the transmission during shifts, often leading to missed shifts or slow shifting in racing conditions. A less compliant plastic or metal bushing is the ideal solution, but without a spherical bearing, the bushing will cause the cables to bind and fatigue. That's why ACUITY has designed this kit with a custom acetal and aluminum spherical bushing. Also unlike most bushings on the market, ACUITY's design incorporates elastomer rings to provide the best fit possible with your cables. Experience a solid, smooth shift that will make you fall in love with your car again.

• O-Ring Loaded Design Wear-Compensates
• Spherical Design decreases resistance in shifts
• Solid Construction provides a stiffer feel than the OEM Rubber
• Includes all stainless steel hardware to avoid corrosion

Shifter Base Bushings

Much Needed Refinement for the OEM Shifter

The OEM base bushings on most Hondas and Acuras are made from highly compliant rubber. Thanks to leverage, the small amount of compliance the rubber adds equates to a very noticeable "spongy" feeling in the shift knob during shifts. This bushing kit replaces the OEM rubber bushings with rigid 6061-T651 aluminum making for a much more decisive shift, even with a stock shifter. As an added touch, the bushings are coated in a purple Type 2 anodized finish, laser etched, and paired with class 10.9 flat-head mounting bolts.

• Reduces compliance by replacing the OEM rubber bushings with solid aluminum
• Includes (4) upper bushings, (4) lower bushings, and (4) class 12.9 M6 mounting bolts
• Purple anodized finish
• Laser-etched acuity logos

Shifter Centering Spring Upgrade

A Simple Mod You'll Enjoy On Every Drive:

If you've ever found the centering action of your 11th Gen Civic or 5th Gen Integra to leave you wanting a sportier feel, this product is the solution. This spring is carefully designed to deliver a more aggressive centering action on your OEM shifter. The larger wire diameter increases centering force by 50% compared to stock and imparts a snappy, tactile feel to the shifter's centering action. In addition to the Shifter Centering Spring itself, each kit is supplied with retaining rings needed for installation and a small packet of premium grease to re-lubricate the shifter after removing the OEM spring.

• Increases centering force on OEM shifter by approximately 50%
• Powder coated for corrosion resistance
• Includes grease packet for use during installation
• Includes grooveless retaining ring for use during installation

Short Throw Adapter

Shorter Throw, Less Play, Stiffer Feel:

Refining your Civic or Integra'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 Short Throw Adapter for the 11th Gen Honda Civic and 5th Gen Acura Integra can be appreciated as much during street driving as at the track. This Short Throw Adapter reduces the mechanical advantage of the shift lever to deliver 20% shorter gear throws. 300 series stainless steel construction makes these Short Throw Adapters strong and highly corrosion resistant. Acuity's unique clamping design ensures the adapter will stay fastened, even with a modest amount of torque. 

By reducing the throw at the shifter, you are effectively reducing the play in the shifter cables by the same amount you are reducing the throw. When the throw is reduced at the transmission, the play from the cables remains the same while the throw is reduced. This is the primary motivation for Acuity's choice to design short throw adapters that affix to the shifter rather than the transmission.

Each kit includes an alcohol wipe so that the shift lever can be cleaned before installation. No grease is required when installing this product as the included PTFE pivot cap is self-lubricating. 7.5mm (0.3") thick spacers are also included to raise the height of the shifter slightly to help the short throw adapter clear the frame the shifter mounts to, and the included self-retaining washers help to keep the spacers in place during installation. Do not install the Short Throw Adapter without also installing these spacers, as omitting the spacers may result in interference between the moving parts of the shifter and the cast aluminum bracket the shifter mounts to.

• Reduces shift throw of OEM shifter by approximately 20%
• 300 series stainless steel construction
• Unique clamping nut design for secure installation
• Spacers included to raise shifter 7.5mm (0.3in)

Shifter Rocker Upgrade

Narrower Gates, Less Play, Stiffer Feel:

Refining your Civic or Integra'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 11th Gen Honda Civic and 5th Gen Acura Integra can be appreciated as much during street driving as at the track. Altered geometry reduces the mechanical advantage of the rocker to provide 10% narrower gates and a stiffer shift feel in the lateral (left/right) direction. Much like how a short throw adapter reduces the distance in the longitudinal (forward and reverse) direction while changing gears, this Shifter Rocker Upgrade reduces the distance in the lateral (left and right) direction while changing gates (shifts between gears 2/3 or 4/5). 6061 aluminum is used in place of the OEM plastic, meaning less flex when shifting forcefully and better feedback from the transmission during shifts. The rocker's main pivot uses a precision bronze bushing to reduce play and friction. ACUITY's unique patent-pending spherical joint design incorporates low-friction, self-lubricating bushings that reduce friction while naturally eliminating play 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. Also included with each kit is a packet of premium grease and 2 retaining rings needed for installation. 

• Reduces OEM shifter gate spacing by approximately 10%
• Wear-compensating spherical joint reduces play while in gear
• Bronze pivot bushing delivers smoother operation, less friction, and reduced play compared to stock
• CNC machined from billet aluminum for improved precision and increased stiffness.
