Hardworking Bushings
Carrying heavy loads or towing heavy trailers in your truck increases the workload for your leaf springs and accelerates the rate of deterioration for the aging rubber bushings in your rear suspension. Luckily, SuperPro developed polyurethane leaf spring bushings for your Chevy Silverado 1500 and GMC Sierra 1500 to provide a more durable solution. Not only are polyurethane leaf spring bushings more durable than rubber bushings, polyurethane also decreases wheel hop by limiting bushing deflection.
Material Superiority
If your truck sees a lot of hard use, strengthening your suspension with an upgrade to polyurethane is a smart move thanks to the robustness of the material. Polyurethane resists breaking down from chemicals, oils, salts, UV rays, heat, age, and repeated impacts. Polyurethane is so well engineered to withstand abuse that Monster trucks choose polyurethane for their bump stops, making SuperPro bushings the perfect choice for a hard working GMC or Chevy.
Defense Against Damage
Installing stronger leaf spring bushings on your Sierra or Silverado increases longevity as well as reducing rear axle deflection to prevent damage to critical driveline components and erratic handling from thrust angle changes. Maintaining the geometry of your rear suspension is also beneficial to prolonging tire life by reducing tire scrub and preserving alignment settings. Shore up your suspension with SuperPro's leaf spring bushings that are able to maintain your Silverado or Sierra's suspension geometry under heavy acceleration, braking, and cornering.
Have Bigger Wheels?
SuperPro leaf spring bushings are also beneficial to Silverado or Sierra owners who have added larger wheels or tires seeking additional traction. However, that additional traction and increased weight stresses the aging rubber bushings to their breaking point. Installing polyurethane bushings restores your truck's ability to properly locate the leaf springs and rear axle to harness the performance potential for your wheel and tire combination.
