Description

Lifted trucks and SUVs often struggle to maintain proper load support. The Tuff Country 40001 4" Rear Air Bag Spacer Kit (Non-Tapered) is a Lift-Rite solution that lets you continue using Firestone or Air Lift airbags on a lifted rear suspension with confidence.

  • Kit contents: Pair of 4" rear spacers (non-tapered) designed for use with your existing air bag system
  • Lift height: 4" rear spacer to restore appropriate ride height on lifted vehicles
  • Non-tapered design: Simple, standard spacer compatible with non-tapered lift blocks
  • Material: Made from 1/8" reinforced tubing for durability and long-lasting performance

This spacer kit addresses common lift-and-load scenarios, such as towing a heavier trailer, carrying heavy gear, or supporting commercial loads, by maintaining proper rear height and air bag function. By letting airbags work effectively on a lifted platform, you’ll experience smoother handling, improved load control, and better stability when the vehicle is under load—without sacrificing ride quality.
