LS Truck/SUV Hot-Side Turbo Kit (1999-2013 GM 4.8L / 5.3L / 6.0L)

Designed specifically for 1999-2013 GM LS-powered trucks and SUVs, this hot-side turbo kit fits 4.8L, 5.3L, and 6.0L Vortec engines and provides a durable foundation for your turbocharged setup.

Heavy-duty cast iron exhaust manifolds deliver excellent sealing, long-term durability, and consistent performance under high heat and boost conditions. Both manifolds utilize V-band connections for easier installation and serviceability, while the driver-side V-band connection eliminates the need for a factory-style gasket at that junction.

A 2.5-inch two-piece stainless steel crossover pipe simplifies installation and includes a 44mm V-band wastegate flange compatible with most common 44mm V-band wastegates. An integrated flex joint helps absorb engine movement and vibration, reducing the risk of cracks and exhaust leaks over time.

The included 3-inch stainless steel downpipe attaches to the turbocharger using a V-band connection and offers flexible exhaust routing options. Connect it to your existing exhaust system or use the included turndown for off-road applications.

Measuring approximately 25.5 inches flange-to-flange across the manifolds (without clamps), the compact design fits both factory truck/SUV applications and many LS swap projects where space is at a premium.

Kit Includes:

  • Manifold Material: Cast iron (passenger and driver side)
  • Turbo Flange: 4-bolt T4 flange, 76mm (3.00") ID
  • Crossover Pipe: 2.5" two-piece stainless steel crossover with flex joint and V-band flange
  • Wastegate Flange: 44mm V-band
  • Downpipe: 3" diameter with V-band turbo connection; includes turndown for off-road setups
  • V-Band Turbo Connection: 3.50" ID
  • V-Band Downpipe Connection: 3.25" ID
  • Overall Width: Approximately 25.5" flange-to-flange across manifolds (without clamps)
