Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.

  1. Modified ride height compared to Sport Springs to maximize optimal suspension geometry.
  2. Further increasing the spring rate to enhance overall performance. The increase in spring rate is based on the upper limits of the vehicles factory shock valving.
  3. Maintaining optimal comfort level for street use.

Spec R springs are wound with the same engineering and material as our sports springs. With the exception of stiffer rates and slight change in ride height; you can expect the same characteristics as our sports springs.

Note: Vehicle drop rate is based on the year, model and option of the test vehicle, and may vary based on each vehicle condition.
All the specs above are subject to change without any notice.

Suspension

Suspension

We have suspension kits, shocks and struts, strut rods, control arm, disc brakes, lowering springs, tie rod end adjusting sleeves, you name it we've got it.

Car & Truck suspensions also are crucial for providing stability on the road. Since these vehicles are heavier and might also be carrying additional weight, the suspension must be able to assist with handling uneven roads. The suspension also helps prevent trucks from tipping. The suspension also needs to help cushion the ride so the cargo and equipment remains protected over bumps and other imperfections in the road. Cushioning the ride also helps improve driver comfort. The suspension allows the tires and axles of the truck to move independently from one another, instead of the axle being attached to the frame directly. This helps soften the impact to the vehicle and helps absorb the impact of cracks, bumps or dips in the road
