It fits stock to 6" lifts.

Apoc's adjustable rear trailing arms for the 1999-2014 Chevy Tahoe/Suburban provide a significant upgrade over stock controls. While factory trailing arms work well with factory-sized tires and suspension, larger sizes require longer, more substantial control arms to maintain proper pinion angle. These high-quality trailing arms are designed to support correct suspension and driveline geometry, ensuring your vehicle handles as well as it did when it was stock, if not better. Don't sacrifice reliability for appearance - with adjustable controls arms that can accommodate up to 6" of lift, you can easily upgrade without compromising your driveline angles and risking vibration or premature U-joint failure. Whether you're starting with a mild lift and plan to upgrade later or already have a lifted vehicle, these arms are the perfect solution for maintaining optimal performance.

Control Arm lengths 

If upgrading from factory control arms, ensure you set the length to the correct lift size to keep your steering geometry accurate. The larger the lift, the longer the control arms. Don't assume what your lift size is. Contact the lift kit manufacturer to verify your lift size if you are unsure. The Instructions will give you the measurements to set each control arm to match your lift, and an alignment is recommended after installation to ensure all alignment angles are proper.
