RiAiCiING 4” LS Swap Cold Air Intake Kit
- Compatibility: Universal design fitting LS1, LS2, LS3, LQ4, LQ9, LY6, and more.
- Positioning: Driver or passenger side filter position with added clearance between radiator and pulleys.
- Airflow: Designed to provide a less restrictive path, increasing air volume for cooler intake air.
- Notes: Supports speed density and round MAF sensors; MAF-related accessories may require additional clamps or couplers.
This kit targets improved throttle response and engine growl when accelerating, with emphasis on broad LS compatibility and fitment in varied restomods. Installation considerations include sensor compatibility and radiator clearance in some chassis.
LS Swap Retrofit Engine Aluminum Oil Pan Kit
- Application: For 55-87 GM rear-wheel-drive builds, suitable for small- or big-block Chevy layouts.
- Material & Fit: Cast aluminum with maximum chassis clearance; lightweight yet durable.
- Engine Positioning: May require adjustment up/ down or fore/ aft for optimal clearance.
- Capacity: Sump and total oil capacity compatible with LS-based configurations; supports full-length windage tray.
Aluminum construction reduces weight and helps with heat management, which is beneficial in tight engine bays often encountered in LS swaps.
LS Engine Serpentine Bracket, Alternator & Power Steering Pump Swap
- Function: Reorders belt routing to optimize space for LS intake manifolds and accessory placement.
- Compatibility: Works with common LS1/LS2/LS3/LS6/LS7 engines used in trucks and SUVs.
- Installation: Improves pump placement and provides cleaner serpentine routing for easier assembly.
This bracket system helps improve fitment in tight engine bays where belt and pulley interference can be an issue during LS swaps.
maXpeedingrods LS Engine Swap Mount Adapter Kit
- Purpose: Engine swap mounting system for G-Body cars, enabling LS engine installation into 1973-1988 models.
- Compatibility: Supports LS1/LS2/LS3/LS6/LSX/LQ4/LQ9 with common 4.8L-6.2L variants.
- Features: Powder-coated spacers for anti-corrosion and ease of installation.
These adapters are designed to align engine mounting with OEM-like precision, aiding fitment and stability in classic chassis while retaining performance orientation.
Aluminum Single Plane Carb Intake Manifold For GM LS Gen III or IV
- Fitment: Designed for LS Gen III/IV engines with LS3/L92-style rectangular ports.
- Performance: A single-plane intake aimed at maximizing top-end horsepower in appropriate configurations.
- Reference: Ensures better throttle response and consistent performance characteristics when paired with high-flow components.
Note: This manifold is oriented toward specific intake port configurations and may require compatibility checks with existing fuel delivery and sensor arrangements.
BuliBoao 4” LS Swap Cold Air Intake Kit
- Fitment: 4-inch intake kit compatible with LS1/LS2/LS3/LQ4/LQ9/LY6 engines.
- Quality: High-quality materials designed for durability and long service life.
- Install: Easy to install with no modification required in many LS swap applications.
This kit aims to provide a straightforward upgrade path for improving airflow in LS-powered builds with broad engine compatibility and simple installation.
36″ LS Throttle Cable and Braided Cable Kit
- Fitment: 36-inch braided stainless throttle cable kit for LS1 engines and related LS swaps.
- Adjustability: Can be cut to a custom length for precise pedal-to-throttle linkage alignment.
- Durability: Extended life liner and heavy-duty construction for smoother operation.
Important for LS swaps where throttle control needs exacting cable length, especially in retrofits with aftermarket pedal assemblies.
LS Swap Motor Mounts Adapter Plates
- Function: Allows easy mounting of LS engines into vehicles originally fitted with small-block Chevys.
- Design: OEM-like fit with alignment to move crankshaft centerline slightly for performance gains.
- Material: CNC milled aluminum for accuracy and durability.
The adapter plates are designed to optimize alignment and stability, contributing to reliable performance in LS swap projects.
Buying Guide: Key Considerations for LS Swap Carb and Fueling Upgrades
- Engine compatibility: Confirm engine family (LS1/LS2/LS3/LS6/LSX, etc.) and vehicle chassis to ensure correct fitment of intakes, oil pans, and mounts.
- Clearance and fit: Evaluate radiator, belt, and accessory clearances in your chosen chassis. Some parts require adjustments or additional hardware for clearance.
- Sensor and fuel system compatibility: Check MAF sensor types, fuel rails, and throttle linkage to ensure components work together without wiring or calibration conflicts.
- Material and weight: Aluminum components reduce weight and help with heat management, which can influence oil pan clearance and overall balance in the engine bay.
- Ease of installation: Favor parts with straightforward installation steps and minimal modifications. For some classic chassis, professional alignment may still be recommended.
- Durability and finish: Powder-coated or corrosion-resistant hardware helps longevity in exposed environments or under hood heat cycling.
- Future upgrade paths: Choose parts that accommodate potential sensor upgrades, different throttle bodies, or future engine variants to extend use across multiple builds.
