Danti LS Engine Lift Plate For Gen III/IV Engines
The Danti lift plate is designed for Gen III and Gen IV LS family engines, including LS, LSX, LS1, LS2, LS3, 6.0L, and 5.3L variants from 1997 onward. It installs by bolting to the engine block (intake manifold and valley cover tray must be removed) and is made from high-quality iron for strong, reusable service. Best for professional shops or serious hobbyists who regularly swap engines and need a stable, secure lift.
Who it’s best for: mechanics and enthusiasts performing frequent engine swaps who require a robust lift solution with included hardware. Limitation: installation requires removal of intake manifold and valley cover tray to secure the plate properly.
SoloSwap LS Mock Up Engine Swap Short-Block
The SoloSwap LS mock-up short-block is designed for easy engine fit testing, replicating Gen 3 and Gen 4 LS block sizes and accepting factory or aftermarket LS heads. Weighing about 18 pounds (short block) or 35 pounds (long block), it can be handled by one person for height-adjusted positioning. Best for mock-up and fitment checks before final installation.
Who it’s best for: builders planning head or manifold testing before a full install; avoid if you need a working engine cradle—this is a mock-up, not a running engine.
Oil Pump Priming Adapter Kit For All GM LS Engines
The priming adapter kit is compatible with LS1, LS2, LS3, LSX, 4.8L, 5.3L, 6.0L, and 6.2L engines. It primes the oiling system before first startup or during rebuilds, helping oil reach bearings and valvetrain components. Best for pre-lubing during engine assembly to prevent dry starts.
Who it’s best for: builders doing a fresh LS build or engine refresh where oiling system priming is desired; consider it essential for long-term wear protection, especially after reassembly.
Front Wet Sump Retrofit Engine Oil Pan For LS
This front wet sump retrofit oil pan is designed for LS-based engines including LS1, LS2, LS3, and LSX variants with displacements like 4.8L and 6.2L. It replaces other pan configurations in front-sump installations. Best for swaps requiring a modern sump layout and improved oil control in engine bays with space constraints.
Who it’s best for: builders seeking compatibility with front-sump configurations; avoid if your build requires a different sump type or if space constraints complicate mounting.
Bonbo LS Engine Lift Plate
The Bonbo lift plate offers five lifting points to balance engine weight during extraction or installation. It is compatible with Gen III and Gen IV LS family engines, including LSX, LS1, LS2, LS3, LQ4, 6.0L, 6.2L, 5.3L, 4.8L, and 5.7L variants from 1997 to today. Best for precise lifting and safer engine handling in tight engine bays.
Who it’s best for: workshops needing more control over lift balance; limitation: depending on vehicle configuration, you may still need to remove certain components for secure mounting.
JEGS Engine Cradle For GM LS Series
The JEGS engine cradle is a heavy-duty, all-steel construction with a 1,000 lbs capacity and a yellow powder-coated finish. It’s designed to support GM LS series engines during service, storage, or transport and includes storage hardware. Best for reliable cradle support during heavy engine work.
Who it’s best for: shops requiring a robust support base for LS engines; limitation: it’s a cradle accessory rather than a lift device, so pairing with a dedicated hoist may be needed for full installation tasks.
LOSTAR LSX LS Heavy Duty Lift Plate
The LOSTAR lift plate is designed for Gen III and Gen IV engines, fitting LSX, LS, LS1, LS2, LS3, 6.0L, 5.3L, 5.7L from 1997 to current. It features five lift holes to balance and tilt the engine during removal or installation and emphasizes durability and precise balance.
Who it’s best for: users needing improved balance control during removal or installation; advantage: multiple lift points, limitation: ensure compatibility with your vehicle’s engine bay geometry.
Buying Guide
What type of LS engine setup are you planning?
Decide if you need a lift plate for frequent swaps, a mock-up block for fit testing, or an oil priming tool for pre-start protection. For ongoing swaps, prioritize lift plates with multiple balance points and robust hardware.
How important is lifting balance and tilt control?
Look for plates with multiple lift points (five-point systems are common) to tune balance as the engine moves in and out of the bay. Balanced lifts reduce the risk of tipping and damage to surrounding components.
What are your space and mounting constraints?
Some oil pans, valley covers, or intake manifolds must be removed to install a lift plate. Check if your engine bay geometry permits the plate’s mounting pattern and whether additional adapters are needed.
Is pre-lubing necessary for your build?
If you’re doing a rebuild or reassembly, a priming adapter for the oil system helps prevent dry starts. This is especially valuable after long storage or significant engine work.
Durability and compatibility considerations
Choose plates made of high-quality iron or steel and verify Gen III/IV compatibility (LS1, LS2, LS3, LSX, 4.8L, 5.3L, 6.0L, 6.2L). Durability matters for repeated use and reliability in professional settings.
Practical comparison tips
- Best for frequent swaps: select a plate with multiple lifting points and strong hardware.
- Better for mock-up testing: a SoloSwap-style short block is convenient for fit checks without a full engine.
- Choose an integrated oil priming tool if you’re rebuilding or refreshing multiple LS engines.
FAQ
- What is a lift plate and why do I need one for a 5.3 LS crate engine build?
– A lift plate attaches to the engine block to provide secure attachment points for a hoist, helping you lift and position the engine safely during swap or installation.) - Can I use a lift plate with an aftermarket LS crate engine?
– Yes, most lift plates are designed for Gen III/IV LS blocks and support aftermarket configurations when properly bolted and aligned. - Is oil pump priming important for LS builds?
– Priming the oiling system before startup can prevent dry starts and protect bearings during initial engine run-in.
