Spring Rate Alterations
The original springs, selected by GMC engineers, were calibrated to absorb impacts across a spectrum of conditions, from highway cruising to navigating uneven terrain. A lowering kit often necessitates a change in spring rate, typically a stiffening, to prevent bottoming out with reduced suspension travel. A stiffer spring, while providing more controlled body roll in corners, transmits more road imperfections directly to the cabin. Imagine driving over railroad tracks; the jolt, once softened by the factory suspension, now resonates more intensely through the frame, a constant reminder of the modification’s trade-offs.
-
Shock Absorber Damping
The shock absorbers are the unsung heroes of ride quality, controlling the oscillations of the springs and mitigating the severity of bumps. Lowering kits often include shorter shocks, and their damping characteristics must be carefully matched to the altered spring rates. Inadequate damping can lead to a bouncy, uncontrolled ride, where the truck feels perpetually unsettled. Picture traversing a winding country road; without properly valved shocks, the vehicle may exhibit excessive body roll and a disconcerting lack of composure, undermining both comfort and confidence.
-
Suspension Travel Reduction
Lowering a vehicle inevitably reduces the available suspension travel, the distance the wheels can move vertically before reaching the bump stops. When the suspension bottoms out, the impact is transmitted directly to the frame, resulting in a jarring and often unpleasant experience. Envision encountering a pothole at speed; with reduced travel, the suspension is more likely to abruptly compress, sending a sharp jolt through the vehicle and potentially damaging suspension components. This limited travel becomes particularly apparent when the truck is loaded or towing, further compromising ride quality.
-
Axle geometry and bump steer
Changing a 2014 GMC sierra 1500 suspension can change it’s axle geometry. Alterations with the suspension travel, angles of control arms and linkages, especially the steering linkage may cause bump steer, an unwanted change in steering angle.
