Belltech rear axle Flip Kits are designed application specific to relocate or Flip the rear axle of your truck from beneath the leaf spring to above, providing a dramatic amount of drop. Each Belltech rear axle Flip Kit is engineered for each individual application and manufactured with high quality steel and feature a durable powder coated finish, Grade 8 hardware and installation instructions. Belltech frame rail C-Notches are included in most Flip Kits.
Belltech flip kits are designed to offer a more aggressive drop for that traditional "slammed" appearance. A lowered center of gravity and no modification to the oem leaf spring aid in retaining the oem ride quality.
