Setup for your modified machine
Long-travel arm geometry can change the leverage acting on the springs. Match the package to the actual suspension kit, shock fitment and load; installing springs alone does not create additional suspension travel.
Choosing your spring package
The Full Kit replaces upper and lower springs on all four shocks. Lowers Only replaces just the lower springs; the upper springs and hardware retained must be suitable for the resulting setup. A tender-only kit replaces the tender springs while retaining the main springs.
How the spring stack works
While both stacked springs are free to compress, their combined rate is lower than either spring alone. On a setup using a crossover stop, the divider reaching that stop changes which spring can continue to compress. The lower main spring then provides the firmer stage. Spring selection and crossover setup both matter; replacing springs does not change the shock’s internal damping.
Installation overview and setup
Follow the Polaris service procedure for your exact model year and the instructions for your installed shocks and aftermarket suspension or portal kit. Professional installation is recommended. The video below is a general spring-installation overview.
- Record the starting ride height on level ground and note the vehicle's normal operating load.
- Safely raise and support the vehicle. Unload the suspension before preload adjustments and release spring tension with suitable equipment before removing retainers.
- Install the springs supplied in your selected package using the applicable front and rear shock procedures. Torque removed fasteners to your exact model's specifications.
- Lower the vehicle and move it forward and backward to settle the suspension before remeasuring.
- Follow the shock manufacturer's adjustment limits. Make small changes with the suspension unloaded, then settle and remeasure. Keep left and right settings matched on each axle.

Portal lift size, suspension geometry, tires, and load can change the appropriate target; confirm your build-specific settings with All Thingz UTV.
| Tire size (inches) | ATU front baseline (inches) | ATU rear baseline (inches) |
|---|---|---|

| 30 | 15 | 14.5 |
| 32 | 16 | 15.5 |
| 33 | 16.5 | 16 |
Measurement reference: Use the measurement points specified in the instructions for your suspension configuration; keep the same points when comparing before and after measurements. Tire dimensions, pressure, passengers, accessories, and suspension setup affect the result. Listed tire sizes do not confirm tire fitment.
