2000–2006 Chevy Tahoe / GMC Yukon / Suburban 1500 Lift Kit FAQ

How are TORCH extended rear shocks designed to be installed on my 2000–2006 Tahoe, Yukon, or Suburban?

Our TORCH extended rear shocks for the 2000–2006 Tahoe, Yukon, and Suburban 1500 are meant to be installed with the rubber boots and rods facing upwards. Due to their twin-tube design, the shocks need to be installed in this specific orientation for proper function. Installing the shocks with the boots facing downwards will interfere with the movement of the fluids inside the shock body, preventing proper dampening.

Why can’t I use a Silverado 1500 lift kit with rear blocks on my 2000–2006 Tahoe, Yukon, or Suburban 1500?

The 2000–2006 Tahoe, Yukon, and Suburban 1500 use coil springs for the rear suspension, rather than the leaf pack used by the Silverado 1500 from those years. While some of the suspension components are shared across these platforms, the SUVs utilize a different rear suspension type, meaning you cannot install lift blocks. Lifting these vehicles requires rear spacers designed specifically for coil spring setups.

Do I need a special torsion key unloading tool to install the front lift, or can I use a standard C-clamp?

We strongly advise against using a standard C-clamp. Torsion bars hold an immense amount of pressure, and standard clamps can easily slip, bend, or fail, posing a serious safety risk during installation. We recommend using a dedicated Torsion Key Unloading Tool to safely release tension on the factory keys and install the new keys securely.

What is the maximum tire size I can run with a 3" TORCH lift kit on my 2000–2006 GM SUV without rubbing?

With our 3” TORCH lift installed, we recommend up to a 33” maximum diameter tire. While 33" tires are a common choice with a 3" lift, minor fender trimming may be required depending on your wheel offset and tire width. If your priority is minimizing the potential for rubbing or clearance issues without trimming, a tire around 32" in diameter would be a more conservative choice.

Will installing a 3" front torsion key lift affect my alignment, CV axle angles, or ride quality?

Our TORCH lifts have been thoroughly tested to function up to a 3” lift above stock settings. With our kit installed on an otherwise factory suspension, the wheels can typically be aligned without issue. The kit maintains a ride feel that is close to the stock ride. On 4WD applications, the front lift does affect the angle of the CV axles, but adjustments or differential drops are not strictly needed as the kit functions reliably within factory tolerances.
