Rear powertrain zone
Engine components
Plan the scope before choosing internals: repair, stock-style refresh or a modified engine. Keep machining, assembly and calibration requirements in the same conversation.
Explore engine componentsRear airflow zone
Intake & airflow
Start with the installed airbox, turbo inlet or throttle-body connection. Compare dimensions, filter access and the rest of the intake path before choosing a component.

Cooling
Work from the system you need to service: engine coolant, charge air or another circuit. Compare connection points, dimensions and installation space.

Suspension
Record current shocks, springs, arms and electronic controls. Match the project to tire size, passengers, cargo and terrain before choosing the next component.

Wheels & wheel packages
Compare bolt pattern, diameter, width and offset together. Confirm brake clearance and whether a listing includes wheels only or a complete wheel-and-tire package.

Tires
Choose around terrain and intended use, then check size, wheel compatibility and vehicle clearance. Review front/rear positions and whether the price is per tire or package.

Lighting
Plan where the light mounts, where the wiring runs and how it is switched. Compare beam pattern, mounting dimensions and the electrical requirements in each listing.

Body & protection
Start with the exact body and seating layout. Compare coverage, mounting points and access for service before choosing panels, guards or protection pieces.

Steering & interior
Plan around the driver’s position and existing equipment. Check mounting interfaces, control clearance and what must stay accessible in the cockpit.

ECU & tuning
Choose the ECU approach and fuel first. Compare what each package includes, then match calibration to the hardware already on your build.
Engine components
Plan the scope before choosing internals: repair, stock-style refresh or a modified engine. Keep machining, assembly and calibration requirements in the same conversation.
Intake & airflow
Start with the installed airbox, turbo inlet or throttle-body connection. Compare dimensions, filter access and the rest of the intake path before choosing a component.
Exhaust
Compare the complete exhaust path, not just the outlet. Identify existing headers or turbo connection, sensor provisions and the calibration requirements of the selected system.
Turbo systems & control
Identify factory turbo hardware or an aftermarket conversion first. Check what is actually included: a complete system, replacement component or boost-control accessory.
Cooling
Work from the system you need to service: engine coolant, charge air or another circuit. Compare connection points, dimensions and installation space.
Suspension
Record current shocks, springs, arms and electronic controls. Match the project to tire size, passengers, cargo and terrain before choosing the next component.
Wheels & wheel packages
Compare bolt pattern, diameter, width and offset together. Confirm brake clearance and whether a listing includes wheels only or a complete wheel-and-tire package.
Tires
Choose around terrain and intended use, then check size, wheel compatibility and vehicle clearance. Review front/rear positions and whether the price is per tire or package.
Clutch & drivetrain
Begin with the actual transmission and drive system. Record tire size, engine changes and existing clutch components before comparing belts, clutch parts or driveline hardware.
Brakes
Identify the current calipers, rotors and wheel clearance. Compare replacement dimensions and hardware so the service plan includes the parts the selected job requires.
Lighting
Plan where the light mounts, where the wiring runs and how it is switched. Compare beam pattern, mounting dimensions and the electrical requirements in each listing.
Body & protection
Start with the exact body and seating layout. Compare coverage, mounting points and access for service before choosing panels, guards or protection pieces.
Steering & interior
Plan around the driver’s position and existing equipment. Check mounting interfaces, control clearance and what must stay accessible in the cockpit.
Audio & communications
Decide who needs to hear and communicate, then plan mounts, power and cable routing. Check the exact components included in a kit before adding accessories.
Make room for the next adventure
- Check roof, door and cabin mounting applications against the four-seat body and exact year.
- Include passenger load, cargo and existing suspension equipment when discussing a setup change.
- For power changes, record current turbo and fuel hardware along with ECU identification; the four-seat name alone does not define the tuning requirements.
Before choosing parts
Do all Pro XP 4 years share cabin accessories?
Do not assume so. The 2025 Pro lineup received updates; each accessory needs an explicit year and model application.
Where do I start if the vehicle is already modified?
Record the installed parts and current fuel in My Garage, including suspension and tire changes, before comparing the next upgrade.
