Kartboy

Kartboy offers a range of drivetrain and chassis upgrades designed to tighten up your vehicle's shifting and exhaust. By replacing soft factory bushings with parts that prioritize direct feedback, Kartboy helps eliminate vague shifter feel and excess exhaust movement that can lead to rattles or clearance problems.

  • Shifter bushings that reduce slop and give a more precise, mechanical shift action
  • Stiffer exhaust hangers that keep your exhaust system securely in place
  • Components machined for a factory-like fit with aftermarket performance
  • Simple, bolt-on installation using basic tools — no fabrication required

Built with the enthusiast in mind, Kartboy parts deliver a refined, responsive driving experience without compromising daily drivability.
