This 304 Offroad tender spring kit is made for the Polaris RZR Turbo R 2 seater with Walker Evans shocks. It swaps in higher-quality springs while keeping the factory suspension geometry, and ride height is set with the spanner nuts using the tire-size ride height chart below. It comes in 14 powder coat colors.
Installation uses basic tools and needs no major modifications. Step-by-step instructions and ride height charts are below.
IMPORTANT: Final adjustment is based on ride height, not just preload.
Park the machine on level ground and set it in Park.
Measure and record:
Front Ride Height: At the forward lower A-arm mount.
Rear Ride Height: Just below the rear tow hook.
Clean and lubricate all shock threads using a wire brush and a WD-40 type lubricant.
Lift and secure the front of the machine.
Remove front shocks and place them in a vise.
Loosen the large top spanner nut all the way down to the reservoir (use holes/grooves for leverage).
Remove the lower coupler and slide off the springs.
Install the new tender springs.
Thread the spanner nut down until it touches the top of the tender spring, then add 1 additional inch of preload.
Reinstall the shocks (do not fine-tune yet).
Lower the machine and move it 3–5 feet forward and backward to settle the suspension.
Measure ride height and adjust as needed:
Nut Down = Raises machine
Nut Up = Lowers machine
Note: This is a baseline setting. Every machine varies due to accessories. For precise adjustments, call 304 Offroad at (256) 686-2137.
Pro models with 3 rear springs: Remove the upper collapsed spring.
Shocks do NOT need to be removed.
Loosen the spanner nut.
Slide off the lower collar using its slot.
Install tender springs.
Tighten the spanner nut until it touches the spring, then add 1 inch.
Reinstall wheels if removed.
Remove the rear shocks.
Loosen the spanner nut completely.
Slide springs upward, use the slots to remove the lower collar, and remove springs.
Install tender springs first, then main springs.
Set 1 inch of preload using the spanner nut.
Reinstall shocks and torque all bolts.
With all shocks installed and bolts torqued, lower the machine from the jack.
Move the machine 3–5 feet forward and backward several times to settle the suspension.
Fine-tune ride height using the spanner nuts:
Front: Every ½" of preload = ~1" of ride height
Rear: Every 1" of preload = ~1" of ride height
Adjust in small increments (±0.25” is acceptable)
Nut Up = Lowers ride height
Nut Down = Raises ride height
High Lifter Models: Add +2.5" to ride height specs below (factory-set higher by Polaris).
After final ride height is set:
Install crossover rings 2 inches above the black slider.
Optional silencer rings can be placed between the slider and crossover ring to reduce noise.
