Introduction

This document outlines considerations and solutions for achieving a 2-inch lift on a vehicle equipped with OEM rear airbags, specifically focusing on maintaining compatibility and optimal performance.

Problem

The goal is to lift the vehicle approximately 2 inches, primarily addressing the front suspension, while retaining the functionality of the existing OEM rear airbags. Uneven ride height may also be a concern that a lift kit could address. Front struts and possibly control arms may need replacing.

Solution

  1. Front Struts: Consider replacing the front struts to achieve the desired lift. Dobinsons coils to lift the front, in conjunction with Monroe components have been used successfully. Aim for a front lift of 30-40mm.
  2. Rear Spacers: When lifting the rear, it is necessary to retain the bottom of the original airbag setup by using a spacer block. This maintains proper airbag function and travel.
  3. Rear Shocks: When using a 2" lift, match rear shock absorbers to the new lift height.
  4. Airbag Compatibility: The OEM airbags can be retained with a 2" lift if the correct adjustments and components are used.

Relevant Parts

  • Bilstein Front Struts: 24-238762 (Verify compatibility with your specific model)
  • Bilstein Rear Shocks: 24-238830 or 24-217897 (BE5-A712/24-217897 combination). (Verify compatibility with your specific model)
  • Rear Airbag Spacer: A spacer block is required to maintain the original airbag bottom mount. (Custom manufactured parts may be required.)
  • Dobinsons Coils: For lifting the front (part number not specified - select appropriate coil for 30-40mm lift).
  • Monroe Components: Suitable for use in conjunction with Dobinsons coils (part number not specified - select appropriate component for application).

Important Considerations

  • Professional Advice: Consult with suspension specialists before undertaking any modifications to ensure compatibility and safety.
  • Airbag Travel: Aim to maintain the rear airbag travel within the original specifications as much as possible.
  • Component Compatibility: When mixing brands, like Dobinsons coils with Monroe components, verify compatibility and proper fitment to prevent issues.
  • Ride Height: Ensure front and rear lift heights are appropriately matched to avoid adverse handling characteristics.
