Install: Straight forward with nicely written instructions from the manufacturer. Most difficult was dealing with the massive 22.5 wheels/tires and 450ft/pd lug nut spec. Recommend a torque multiplier and carbide drill bits for this job.
Ride Review: Excellent, Excellent, and still Excellent! Reduced road noise! Sway greatly attenuated resulting in reduced input at steering wheel. Worth every penny and the 25% holiday discount kept the wallet happy. I highly recommend Sumospring modification to F53 chassis!
