Johnson 2126LSR Slow Leak Down Lifters With Axle Oiling for LS Engines
Best for high-performance LS engines not using DOD/AFM systems. These slow-leakdown link-bar lifters include axle oiling and are designed to handle higher open spring pressures (500+ lb). They require removal of plastic lifter trays due to the tie-bar design. Choose this if you want durable, race-style lifters with robust oiling for boosted builds that avoid AFM/DOD complexity.
Who it’s best for: builders seeking consistent lift with race-style hydraulics in LS engines that do not run DOD/AFM. Limitations: requires removing lifter trays and understanding the tie-bar layout.
Johnson ST2116LSR Short Travel Slow Leak Down Lifters
Best for LS engines that require precise bleed-down with minimal plunger travel. These short-travel, slow-bleed lifters are designed for all LS platforms and use a tie-bar configuration, so you’ll remove the plastic lifter trays. They deliver consistent lift and repeatable rotation characteristics. Ideal when you want stable valve behavior under boosted cam profiles.
Who it’s best for: enthusiasts needing tight travel lifters with predictable bleed-down. Limitation: tie-bar setup requires tray removal during installation.
LS Swap Motor Mounts Adapter Plates
Best for converting a small-block Chevy to LS power with proper alignment. These billet aluminum plates move the crankshaft centerline up by 0.17 inches for improved fitment. The package includes two adapter plates and all necessary bolts. Choose this if you need precise mounting to accommodate LS engines in non-LS chassis and strive for OEM-like geometry.
Who it’s best for: builders performing LS swaps into traditional SBC vehicles. Limitation: adapter fit relies on bolt-on compatibility with your specific frame and mounts.
LS Engine Lift Plate Hoist For Chevy
Best for engine installation and extraction tasks on Gen III/IV LS family engines. The lift plate features five main lift holes for balance, plus ten bolt holders for fine-tuning tilt. Installation is straightforward: remove the intake manifold and valley cover tray, then mount the plate to the engine block. Choose this for easier, repeatable engine handling during boosted builds.
Who it’s best for: hobbyists and shops performing frequent LS engine swaps. Limitation: requires removal of intake manifold for installation in some setups.
Rolling Engine Storage Stand (LS Compatible)
Best for safe storage and maneuverability of LS engines and transmissions. This rolling stand supports heavy LS V8s and features swivel casters for easy movement in garages or workshops. It provides a stable base for storage between rebuilds or during turbo or supercharger installations where space is constrained.
Who it’s best for: shops needing portable engine storage with agile positioning. Limitation: not a replacement for a full engine stand when performing dynamic engine work.
Buying Guide: Key Considerations For LS Boost Builds
What should you evaluate when selecting LS components for boosted performance? Start with engine role, fitment, and installation complexity.
- Vehicle compatibility: Confirm engine model, generation, and mounting compatibility with your chassis.
- Lift and bleed-down behavior: For lifters, understand travel, bleed-down rate, and oiling method to ensure valve train stability under boost.
- Mounting accuracy: Adapter plates and lift plates should align with crank centerlines and bolt patterns to avoid misalignment under load.
- Installation effort: Some parts require tray removal or manifold handling; factor in labor time and space.
- Durability under boost: Look for parts designed to handle higher spring pressures or aggressive cam profiles without bleed-down loss.
Practical Comparison: How To Choose
- Best for not running DOD/AFM systems: Johnson 2126LSR lifters.
- Better for tight travel needs: Johnson ST2116LSR lifters with short plunger travel.
- Choose this if installing LS into a Small Block Chevy: Adapter plates for precise centerline alignment.
- Best for easier engine handling during swaps: Lift plate with multiple balance holes.
- Best for storage and mobility: Rolling engine storage stand with swivel casters.
FAQ
- What is a slow-leak down lifter? A lifter designed to bleed down slowly after closing, improving valve train stability under certain cam profiles.
- Do these LS parts fit all LS generations? Many are designed for multiple LS platforms, but verify fitment for your specific engine model.
- Are adapter plates needed for all LS swaps? Not always; they are essential when mounting LS into non-LS chassis to achieve correct alignment.
- Will lifters work with boosted engines? Lifters designed for higher spring pressures can help maintain lift, but confirm compatibility with your cam and boost level.
- Is a lift plate necessary for engine installation? It simplifies alignment and handling during installs, especially in tight engine bays.
- Are engine stands and storage stands interchangeable? They serve related roles, but a stand is typically used for working on the engine, while a storage stand is for safekeeping.
