-
Unless otherwise specified, tighten all bolts and fasteners to standard torque specifications listed within the OE Service Manual.
-
Suspension components that use rubber or urethane bushings should be tightened with the vehicle at normal ride height. This will prevent premature wear or failure of the bushing and maintain ride comfort.
-
Larger tire and wheel combinations may increase leverage on suspension, steering, and related components.
-
Due to payload options and initial ride height variances, the amount of lift is a base figure. Final ride height dimensions may vary in accordance to the original vehicle ride height. Always measure the vehicle ride height prior to beginning installation.
-
This spring kit can be installed with shocks on your “VEHICLE” by using a floor jack or lift. Select a flat install location. If using floor jack, always make sure to block tires work safely! If removing shocks for installation. Back OEM Preload rings on all shocks before removing. Use a solid-mounted vice for installation.
FOLLOW THESE STEPS FIRST- Measure the current ride height at front center frame point and rear center frame point.
- Write down these measurements for before and after installation notes.
- If removing shocks, label each shock to eliminate installation problems with the piggyback reservoirs positioning/clocking when reinstalling.
- Clean shocks! Remove all dirt and mud.
Ride Height Warning
-
Due to payload options and initial ride height variances, the amount of preload is a base figure. Final ride height dimensions may vary in accordance to the original vehicle ride height. Always measure the vehicle ride height prior to beginning installation.
Important Notes
-
Lift RZR using a floor jack or lift and remove tires.
NOTE: If using a floor jack, raise the rear of the car first and remove the wheels and tires. -
(IMAGE 1) Using a flathead screwdriver, raise the bump stop up around 3 inches.
-
Rotate the spring stack and preload nut counter clockwise until all the preload is removed from the springs.
-
Using your 18mm end wrench and socket, remove the lower shock mount nut and bolt.
NOTE: You do not need to remove the shock completely, just the lower mounting bolt. -
(IMAGE 2) Push up on the spring stack and remove the lower spring retainer.
NOTE: It may be helpful to have an extra set of hands to lift on the spring stack as you remove the lower spring retainer.
-
With the spring retainer out of the way, slide the OEM spring stack
NOTE: Set the springs aside but hang on to the OEM spring retainer and divider as they will be used in reassembly. -
(IMAGE 1) Make sure the shock threads are clean and install the new crossover ring. Making sure not to cross thread the new crossover ring, place it roughly 7″ from the shock body cap. Do not tighten the screws all the way, it will be moved again once preload is set.
-
(IMAGE 2) Install the new rear tender spring with the OEM spring divider with the long side pointing down as shown in the image.
-
(IMAGE 3) Install the new main spring and install the OEM lower spring retainer.
-
Reconnect the shock back to the trailing arm using the 18mm bolt. Torque to 42ft-lbs.
NOTE: Preload and crossover settings should be set at full droop or when the vehicle is still off the ground. -
To set the preload, tighten the preload ring down until it is touching the springs. Once the preload ring is touching the springs, add 6-8 full rotations of preload to the spring stack. keep in mind this is a basic starting point, you may need to add more preload depending on added weight and accessories to your vehicle.
-
(IMAGE 1) Once your preload is set, next the crossover can be set. Crossover settings in the rear should be 4.75″ This measurement should be taken from the bottom of the crossover ring to the top of the spring divider. Remember this is a starting point and more adjustment may be needed later.
-
Once you have the preload and crossover in place you may now tighten the allen screws holding the crossover ring in place.
-
(IMAGE 2) Align or clock lower coil end of new tender spring to upper coil end of new main spring. This reduces spring deflection.
-
Repeat the above steps on the opposite side. Double check torque settings and replace your wheels and tires. Lower the jack and move it to the front of the vehicle.
-
(IMAGE 1) With the front of the vehicle off the ground and the wheels and tires removed, Use a flathead screwdriver to raise the bump stop up roughly 3 inches.
-
Remove all the preload from the spring stack
-
Using an 18mm end wrench and socket, remove the lower shock mount bolt
NOTE: You do not need to remove the upper shock mount bolt, just the lower. -
(IMAGE 2) Lift up on the springs and remove the spring retainer. Set the old springs aside but hang on to the spring retainer and divider as they will be used in reassembly.
-
(IMAGE 1) Locate your new front crossover ring and install it on the front shock body roughly 6″ from the shock body cap. Do not tighten the set screws all the way, the crossover ring will need to be moved once preload is set.
NOTE: Be sure to clean the shock body and threads before installing the new crossover. Be sure not to cross thread the new crossover ring as well. -
(IMAGE 2) Install the new front tender spring and OEM spring divider with the long end pointing down.
NOTE: The front tender spring should be installed with the tighter progressive coils towards the top, this will allow easier access to the crossover ring. -
(IMAGE 3) Install the new front main spring and replace the lower spring divider. Replace the lower 18mm shock mount bolt and torque to factory specifications. NOTE: Preload and crossover settings should be set at full droop or when the vehicle is still off the ground.
-
To set the preload, tighten the preload ring down until it is touching the springs. Once the preload ring is touching the springs, add 6-8 full rotations of preload to the spring stack. keep in mind this is a basic starting point, you may need to add more preload depending on added weight and accessories of your vehicle.
-
Once your preload is set then the crossover can be set. Crossover settings in the front should be 3/4″-1″ This measurement should be taken from the bottom of the crossover ring to the top of the spring divider. Remember this is a starting point and more adjustment may be needed later.
-
Once you have the preload and crossover in place you may now tighten the allen screws holding the crossover ring in place.
-
(IMAGE 1) Align or clock lower coil end of new tender spring to upper coil end of new main spring. This reduces spring deflection.
-
Repeat the above steps on the opposite side. Double check torque settings and replace your wheels and tires.
-
Be sure to go back and add your new ZBROZ reservoir decals.NOTE: It helps to remove the old decals and clean the reservoir body before installing new decals.
-
Drive your vehicle around at slow speed, turning left and right to settle the spring kit. Coast to stop, do not apply brakes to ensure spring kit is naturally settled. Measure and compare ride height measurements with pre-install measurements. Adjust by adding or removing Preload.
-
How to Adjust: With tires on, use a floor jack or lift so that shocks are fully extended and adjust as follows:
-
If Ride Height is too TALL: Rotate OEM Preload ring 2 full counterclockwise rotations, settle spring kit and check.
-
If Ride Height is too LOW: Rotate OEM Preload ring 2 full clockwise rotations, settle spring kit and check.
-
Be sure to reset crossover distance if preload is changed.
Final Results -
Ride Height Gain: average ride height
-
Aggressive Stance: allows fitment of larger tires.
-
Tune-able Progressive Spring Setup: soaks up small bumps better before initiating main springs.
-
Bottoming resistance: increased bottoming resistance with tune-able cross-over rings.
-
Reduced body roll: tuned spring setup delivers increased control when turning and cornering.
-
Race-inspired durability: premium quality / high tensile / light weight / springs that won’t sag.
Final Checks & Adjustments -
Once the vehicle is lowered to the ground, check all parts which have rubber or urethane components to ensure proper torque. Torque lug nuts to the wheel manufacturer specs. Move vehicle backwards and forwards a short distance to allow suspension components to adjust.
-
Turn the front wheels completely left then right and verify adequate tire, wheel, brake line clearance. Test and inspect steering, brake and suspension components for tightness and proper operation.
RECHECK ALL HARDWARE FOR PROPER TORQUE VALUES AFTER 500 MILES, AND THEN PERIODICALLY AT EACH SERVICE INTERVAL THERAFTER. -
Increasing the height of your vehicle raises the center of gravity and can affect stability and control. Use caution on turns and when making steering corrections.
-
Vehicles with larger tires and wheels will handle differently than stock vehicles. Take time to familiarize yourself with the handling of your vehicle.
Wheel Alignment, Headlight, and Safety/Security Systems Adjustment **** -
It is necessary to have a proper and professional wheel alignment performed by a certified alignment technician. Align the vehicle to factory specifications. It is recommended that your vehicle alignment be checked after any off-road driving.
-
In addition to your vehicle alignment, for your safety and others, it is necessary to check and adjust your vehicle headlamps for proper aim and alignment.
-
If the vehicle is equipped with active or passive safety/collision monitoring and/or avoidance systems including, but not limited to, camera- or radar-based systems, check and adjust your vehicle’s systems for proper aim and function.
