The DYNATRAC Jeep Gladiator rear coil springs provide 1.5" of lift height and feature a triple rate design with unique DYNATRAC-engineered droop, ride, and overload rates. This triple rate design allows for a soft rate at ride height for superb on-road comfort and a firmer overload rate that increases during compression for excellent bottoming resistance and off-road performance. Additionally, an even softer droop rate is engaged when the suspension approaches full extension for improved off-road ride quality.
