From the first upgrade to the full build

A clear path to your next upgrade.

  1. Your ride comes first

    Your year, model, trim, tire size, fuel and current modifications give the FastUTV team the context for your build request in My Garage.

  2. A plan from our team

    Tell us what you want to improve. FastUTV reviews your request, checks the selected parts against your vehicle details and publishes recommendations to your account.

  3. Build on your terms

    Keep your wishlist separate from your cart. Configure recommended parts individually, or use the build's cart checklist to add ready items together and finish any required options.

What do you want your UTV to do?

More than a list of parts.

Power & response

ECU tuning, engine upgrades and supporting hardware considered together with your fuel choice and current setup.

Explore ECU & tuning

Suspension & handling

A suspension plan starts with your vehicle, terrain and tire size, whether your priorities are ride control or the next round of chassis upgrades.

Explore suspension

Clutch & drivetrain

Clutch configuration and supporting drivetrain parts considered alongside your power level, tire setup and riding conditions.

Explore clutch systems

Planning several upgrades? Choose Complete build in My Garage. Recommendations depend on the details you provide; performance results and fitment are specific to the vehicle, parts and installation.

aRacer RC Super XX PRO stand-alone ECU and wiring harness for the Polaris RZR Pro R

FastUTV-engineered tuning

Put standalone ECU tuning in your build plan.

FastUTV aRacer packages pair a standalone ECU with application-specific tuning. On supported Bosch MG1 applications, the standalone system replaces the factory ECU instead of requiring a factory ECU unlock.

Packages, fuel maps and supporting hardware vary by application. Review the exact product listing and your current modifications with FastUTV. The pictured unit is the Polaris RZR Pro R package, not a universal-fit ECU.

Can-Am. Polaris. Kawasaki.

Explore the existing vehicle collections, then bring your exact year, model and trim into My Garage. A vehicle category is a starting point, not a guarantee that every part fits every trim.
