Nissan 55020-ET80A Rear Suspension Spring

Loosen the rear wheel lug nuts, raise the rear of the vehicle, support it securely on jackstands, and remove the wheels. Position two floor jacks under each coil spring seat portion of the rear suspension beam, then raise the jacks slightly. Remove both shock absorber lower mounting bolts. Carefully lower the suspension arm using the floor jack until the coil spring is fully extended. Remove the coil spring, the rubber mount, and the rubber seat. Installation is the reverse of removal, noting to raise the lower suspension arm with a floor jack until it is at normal ride height, then tighten the suspension beam bolt/nuts to the specified torque, and tighten the wheel lug nuts to the specified torque.

THAT IS CORRECT FOR YOUR CAR. AND YES YOU NEED TO ORDER BOTH
