A Polaris RZR XP 1000 that sits lower than it used to is not automatically suffering from one single failure. Ride height changes can come from spring fatigue, collapsed tender springs, excessive preload changes, added vehicle weight, worn suspension components or an incorrect previous setup. The right repair starts with identifying what changed.
This guide explains how to evaluate RZR XP 1000 suspension sag, what tender springs can correct and when the problem requires more than a spring swap.
Common Signs of RZR XP 1000 Suspension Sag
- The front, rear or entire machine sits visibly lower than before.
- Ground clearance has decreased even though tire size and air pressure have not changed.
- The factory tender springs appear tightly compressed at normal ride height.
- The suspension feels harsh over small trail chatter but still bottoms on larger impacts.
- Added doors, roof, cargo, spare tire or other accessories changed the vehicle’s stance.
- Preload has been increased repeatedly just to maintain height.
One symptom alone does not prove that the tender springs are the only issue. Inspect the complete suspension before ordering parts.
Measure the Machine Before Changing Anything
Park on level ground with the tires set to normal operating pressure. Remove unusual cargo, but leave permanently installed accessories in place. Measure from consistent chassis reference points to the floor at all four corners and record the results. Also record current preload collar positions and photograph each shock.
Measurements help distinguish overall sag from a single low corner. A large side-to-side difference may indicate a damaged component, unequal preload, spring damage or another problem that a four-spring kit alone will not diagnose.
Inspect the Tender Springs
The tender spring is the shorter spring used with the main spring in a dual-rate arrangement. During the initial suspension movement, the tender and main spring work together. Depending on the assembly, crossover engagement or upper-spring coil bind can transition the system to the main spring rate.
Some factory upper springs are intended to be compressed at normal ride height. Their appearance alone does not prove failure; compare ride-height measurements, spring condition and the manufacturer’s intended setup. A properly selected replacement tender can restore that portion of the suspension movement and allow the vehicle to be set at an appropriate ride height without relying only on excessive main-spring preload.

Check for Added Weight
Accessories change the load carried by the springs. A roof, windshield, doors, rear cargo, spare-tire carrier, audio system, winch and passengers can add meaningful weight. A spring setup that worked on a mostly stock machine may sit differently after the build changes.
Replacement tender springs can help recover height and initial compliance, but they do not eliminate the need to select spring rates and preload for the actual machine weight. Heavily modified vehicles may require a more complete spring or shock setup.
Do Not Ignore Worn or Damaged Components
Inspect shock bodies, shafts, bushings, crossovers, retainers, preload collars and mounting hardware. Look for leaking oil, damaged threads, cracked springs, loose hardware or abnormal contact. If a shock is leaking or mechanically damaged, repair the shock before treating the condition as a tender-spring problem.
When Tender Springs Are the Right Fix
A vehicle-specific tender spring kit is worth considering when the shocks and main springs are serviceable, the spring setup is the cause of the complaint, and the kit matches the machine. A compressed factory upper spring alone is not evidence that replacement is needed.
The 2014–2023 Polaris RZR XP 1000 tender spring kit includes front and rear tender springs with separate selections for year range, two-seat or four-seat chassis, and Walker Evans or Fox shocks.
Choose the Correct Kit
| Vehicle | Landing page |
|---|---|
| 2014–2018 RZR XP 1000 or XP 4 1000 | 2014–2018 tender springs |
| 2019–2023 RZR XP 1000 or XP 4 1000 | 2019–2023 tender springs |
| 2014–2023 RZR XP 4 1000 four-seat | XP 4 1000 tender springs |
| 2024+ RZR XP 1000 two-seat | 2024+ tender spring kit |
| 2024+ RZR XP 1000 four-seat | 2024+ four-seat tender spring kit |
Walker Evans vs. Fox Fitment
Do not choose by preference. Select the shock manufacturer already installed on the machine. Read the label on the shock body and compare it with the product options. If the shocks have been replaced with another system, confirm compatibility before ordering.
What to Expect After Installation
Final ride height depends on preload, accessory weight, vehicle condition and actual setup. Measure the machine again after installation and follow the supplied adjustment guidance. Recheck hardware after the initial ride and inspect the springs as part of normal suspension maintenance.
Tender springs should improve the system’s initial spring behavior when correctly selected and adjusted, but they cannot repair leaking shocks, bent components or an incorrectly selected main spring.
Frequently Asked Questions
Can tender springs fix every sagging RZR?
No. They address a specific part of the spring system. Mechanical damage, leaking shocks, incorrect main springs and extreme added weight require separate evaluation.
Should I add more preload instead?
Preload is part of normal setup, but using excessive preload only to recover height can reduce droop and change how the suspension responds. Diagnose the spring condition first.
How much ride-height correction is available?
R1 guarantees an optional 2–4 inch ride-height gain with the correctly matched All Thingz UTV kit and setup. You do not have to choose extra height. Use the kit’s recommended settings and measure under the specified load; a spring swap does not add mechanical suspension travel.
Where can I compare all options?
Start with the Polaris RZR XP 1000 tender spring collection or browse all UTV tender springs by machine.
For the current four-seat chassis, use the dedicated 2024+ Polaris RZR XP 1000 4-seat tender spring kit. Match the listed shock configuration and follow the kit’s setup guidance for the ride-height adjustment you want.
Another vehicle-specific option is the SuperATV tender spring set for 2019–2023 RZR XP 1000 and XP 4 1000. It replaces all four factory tenders; High Lifter editions are excluded.
