T4 Riser Block for High-Performance Applications

If you're running a high-performance turbo setup on your 2001–2010 Duramax, having the right hardware to support it is just as important as the turbo itself. That’s where the PPE T4 Riser Block with Wastegate Port comes in. Built for serious power and precise control, this riser block gives you the clearance and functionality you need when stepping up to a larger turbo like a GT40 or GT42R. The 2 3/8-inch tall riser raises the turbo just enough to improve overall fitment and airflow, especially in tight engine bays. It features an integrated 1 7/8-inch side port designed to accommodate wastegate tubing—perfect if you're running an external wastegate system. Whether you're building a purpose-built drag truck or dialing in boost on a competition sled puller, this block gives you room to route your plumbing cleanly and efficiently.

Durable and Reliable Design

Crafted for durability and heat resistance, the PPE riser is a solid match for demanding race environments. The kit comes ready to install with studs and nuts included, so you can get to work without hunting for extra hardware. Keep in mind, this part is for off-road and racing use only—it’s not legal for highway or off-road registration in California or other CARB-restricted areas.
