This complete kit is designed to eliminate slop, improve shift feel, and give you a tighter, more precise connection between your hand and the gearbox. Each component works together to deliver a more engaging, responsive driving experience for your Subaru.

This kit is made up of 7 key components: TiC Shift Linkage Bushings, TiC Pivot Bushings, TiC Crossmember Bushings, Kartboy Front and Rear Shifter Stay Bushings, the Kartboy Shifter Lever, and Group N Transmission Mount. Together, they transform the shifting experience in your Subaru.

The Complete Setup

• Combine the bushings and lever, and you get a shifter setup that transforms your car. Every gear snaps into place with satisfying precision, making the entire driving experience more engaging and enjoyable. Warning: once installed, you may find it impossible to resist snapping through the gears.

TiC Shift Linkage Bushings

• These replace the soft rubber bushings in the shift linkage joint. Over time, the stock bushings “pack out,” creating excessive side-to-side slop at the end of the stick. Whether your Subaru is an early or later model, and whether you have the stock shifter, optional STi/SPT short shifter, or another aftermarket lever, the stock bushings allow sloppy, vague shifts. Our stiffer polyurethane bushings minimize side-to-side play, prevent packing out, and give your shifts a much more positive, precise engagement—while keeping NVH close to stock.

TiC Crossmember Bushings

• These replace the stock rubber bushings with stiffer urethane for a tighter, more responsive driveline.

Kartboy Front and Rear Shifter Stay Bushings

• Subaru uses soft rubber for the shift lever’s hard mounting points, which results in vague fore-and-aft motion. The Kartboy stay bushings replace the stock rubber with stiffer urethane, eliminating slop and giving each gear a crisp, positive click. The result is a shift feel that is much tighter and more responsive.

Kartboy Shifter Lever

• This short shifter upgrade reduces overall shift throw by 40%, delivering a sharper, more precise feel every time you change gears. The shift knob height is also lowered by 1 inch, creating a sportier and more ergonomic driving position. Precision-built from CNC-machined and TIG-welded 4130 chromoly steel, this shifter is engineered for strength and durability. Installation is quick and straightforward, requiring only basic hand tools and taking under 30 minutes.

OEM STI Group N Transmission Mount

• These Mounts are made of a stiffer material then the stock mounts. These will reduce the motion of your engine during Acceleration, Hard Cornering, and High Revving. They give you a better feel of the engine through the shifter lever and Channel more power through the drivetrain.
