The high-strength-steel dampers are a gas-filled, twin-tube design and tuned by TRD for handling precision and a firm, comfortable ride.Shortened damper bodies allow for a drastically lowered ride height while maintaining an adequate suspension travel.Springs are high-tensile, cold-wound, shot-peened spring steel, that are powder-coated red for long-term corrosion protection.Spring rates are stiffened to 250 lbs/inch, for reduced body roll in hard cornering.Ride height is easily adjustable, lowering the front from 1 to 2-3/8 inches, and the rear from 1 to 2 inches, giving you the freedom to set just the look and handling balance you prefer, without exceeding factory alignment parameters.
