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. When the tender reaches coil bind, the system transitions to the main spring rate.
A stock tender that remains compressed through normal ride height may no longer provide the initial operating range the system was intended to use. 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 a strong option when the existing shocks and main springs are serviceable, the factory tenders have collapsed or lost useful movement, and the goal is to restore initial suspension compliance and ride height adjustment.
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

| 2024+ RZR XP 1000 two-seat | 2024+ 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?
The featured kit offers approximately 2–4 inches of adjustment depending on the selected configuration, preload and vehicle setup. Results vary.
