2026 -2027 9R Only Throttle Body Relocate Kit Trail or Mountain Models

For 2026 9R and newer models, Polaris redesigned the intake by centering the throttle body with the reed cage, resulting in wider center to center spacing on the throttle body.

We have added a youtube video to explain all these otpions and the key differences.

Key differences:

OEM MOD TB  - TB is smaller (50mm) requires less fuel in cruise range resulting in better fuel economy.  Less cost on 2026 and newer

Upshift403 54 x52mm TB larger bore provides better throttle reponse and mid range burst.

Both TB - same top end HP

To accommodate this change, we offer two upgrade options:

Option 1 - Cost-Effective Upgrade

Modify your existing throttle body to work with our fuel rail and hose kit. This option provides the most economical solution; however, reverting back to stock will require plugging the drilled holes in the original throttle body.  

• Fuel rail with fuel lines - comes with quantum fuel filter 
• Cylinder plugs 
• Alignment injectors 
• Add on option - Upshift403 Tuner with License (must have for 2026 and newer)

Option 2 - Performance Upgrade 

Upgrade to a slightly larger throttle body from Upshift403, paired with a 2025 Reed Boot Airbox.  This option offers improved performance and eliminates the need to modify your original components.

• 54mm Upshift403 Throttle Body with Fuel Rail and Lines
• Reed Boot and Airbox 
• Add on option : Quantum Fuel Filter 
• Add on option: Upshift403 Tuner with License (must have for 2026 and newer)

ALL 2026 AND NEWER REQUIRE OUR TUNING DEVICE

WE STRONGLY SUGGEST - having your stock injectors tested and cleaned.
