This T4 turbo pedestal is a must - have for 2001 - 2010 GMC vehicles with 6.6L Duramax engines (LB7, LLY, LBZ, & LMM). Cast from the same high - silicon molybdenum as PPE’s High Flow Race Exhaust Manifolds, it's 3.94 inches (100mm) tall and a new - generation design by PPE engineers. It securely mounts any T4 - based turbocharger. The T4 flange thread is M10 - 1.5. Part Number: 116005059. Note that 2001 - 2004 LB7 applications need pedestal and turbo flange modification for intake runner clearance.

Using this T4 turbo pedestal is simple. First, make sure your vehicle is a 2001 - 2010 GMC with a 6.6L Duramax engine (LB7, LLY, LBZ, or LMM). If it's a 2001 - 2004 LB7 model, you'll need to modify the pedestal and turbo flange for intake runner clearance. Then, securely mount any T4 - based turbocharger to the pedestal. For maintenance, regularly check the mounting to ensure it remains secure. If you notice any loose parts, tighten them up. Keep the pedestal clean to prevent dirt and debris from affecting its performance. This will help the pedestal and the turbocharger work well for a long time.
