1999-2013 GM LS Truck T4 Hot Parts Turbo Kit

This hot-side turbo kit is built for 1999-2013 GM LS-powered trucks and SUVs running 4.8L, 5.3L, or 6.0L Vortec engines. Cast iron exhaust manifolds provide dependable sealing and durability under sustained heat and boost, with V-band connections on both the passenger and driver side — the driver-side V-band eliminates the need for a stock-style gasket at that connection point. A 2.5" two-piece stainless steel crossover pipe simplifies installation and includes a V-band flange sized for most 44mm V-band wastegates, with a flex joint built to reduce vibration-related cracks and leaks. The included 3" downpipe connects to the turbo via V-band and is designed for flexible routing — tie it into an existing exhaust system, or use the included turndown for off-road setups. At approximately 25.5" flange-to-flange across the manifolds (without clamps), this kit's compact width suits both stock truck/SUV installs and LS swap builds. This is a hot-side kit only — turbo, wastegate, cold-side intake tubing, and intercooler are sold separately unless bundled. Confirm California emissions compliance before purchase if applicable in your state. Applications Fits 1999-2013 GM trucks and SUVs with LS-based engines: 4.8L, 5.3L, and 6.0L Vortec. Suited to both stock-configuration truck/SUV builds and LS swap projects, given the kit's compact flange-to-flange width. Installation Manifolds use V-band connections on both sides, removing the need for a stock-style gasket on the driver side. The 2-piece crossover design and flex joint are built to simplify install and reduce vibration-related cracking. The downpipe's V-band connection at the turbo supports flexible routing into an existing exhaust or the included off-road turndown.
