Polaris RZR S 1000 / S4 / Trail S 1000
Your trail, your crew, your setup. Start with S 1000, S4 1000 or Trail S 1000 and explore the parts that make the next project yours.
Choose your next upgrade. Confirm model, year and fitment on each product before ordering.

This guide is for the named 1000 models only, not Trail 900. Confirm the complete model name and year; S4 1000 is not XP 4 1000.

ECU & tuning
Choose the ECU approach and fuel first. Compare what each package includes, then match calibration to the hardware already on your build.
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.
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.
Build around the trails you ride
- Use your complete model name for suspension, axles and body pieces. Do not select on “1000” or “S” alone.
- For a trail-oriented setup, measure the current tire and wheel combination and identify any width-changing modifications before ordering.
- On an S4 project, include passenger and cargo use when discussing suspension setup, without assuming a two-seat kit fits.

Before choosing parts
Are S 1000, S4 and Trail S 1000 the same vehicle?
No. This page groups related browsing needs, not universal compatibility. The 2016 S 1000 and 2023 Trail S 1000 references are two-seat models; the 2019 S4 reference has four seats.
Does this page include Trail 900 fitment?
No. Use a product listing that explicitly names the exact 1000 model you own. A collection may contain broader applications that need individual checking.
