Holley Level LT Engine Swap Kit - Manual Transmission

The Holley Level LT Engine Swap Kit for manual transmissions is part of the Holley Swap Essentials line. It is an application-specific LT swap kit (also called a Gen V LT engine swap package) for installing a GM Gen V LT-based engine with a manual transmission. Each kit is built to work as a system, so you don't have to source engine mounts, transmission crossmembers and related hardware from different vendors and hope they fit together.

Key Features:

• Complete swap solution: The kits are matched components meant to simplify purchasing and planning and to reduce missed or mismatched parts.
• Progressive kit levels: The line has five levels. Level 1 starts with the engine and transmission mounts. Higher levels add a chassis-verified oil pan, headers or exhaust manifolds, a header-back exhaust system and accessory drives. Each level includes the previous level's parts.
• Manual transmission support: Holley's manual kits include the transmission adapters available for that application, so the transmission side of the swap is covered.
• Durable mounts: Holley's Level 1 engine mounts use heavy-duty 11-gauge steel with reinforcement ribs. They have a two-piece bolt-together design and black polyurethane inserts with molded steel locating tabs.
• Sturdy crossmembers: The crossmembers are 3/16-inch steel and are designed around proper driveline angles, with clearance for 3-inch exhaust.
• Hardware included: The kits include the brackets and hardware needed to mount the engine and transmission.
• Quality exhaust components: Kits that include headers use Hooker Blackheart 304 stainless steel headers with 1 7/8-inch primaries.

Every kit is engineered for fitment accuracy, driveline angles and clearance. This helps give a cleaner, more OEM-quality LT swap while leaving a clear path to add parts later. Choose the child option that matches your kit level and application.
