Below you’ll find five detailed product sections. Each section highlights a specific bracket kit, its installation focus, and how it relates to typical LS engine builds that use a Sanden 508/709 compressor. All products are described based on their listed features to help you compare options objectively.
RiAiCiING LS AC Bracket Kit For Sanden 508
This RiAiCiING bracket kit is designed to move a Sanden 508 or 709 compressor high enough to clear frame rails, mounts, and fender walls on compatible LS engines. It supports a broad range of GM LS family engines, including LSX, LS1, and LS3-series variants. The kit notes belt tensioner and pulleys as required components, with potential idler relocation for certain intake manifolds. This option emphasizes engine bay clearance and compatibility with various belt sizes when using different alternator configurations.
ICT Billet LS Truck R4 A/C Bracket Kit
The ICT Billet R4 A/C bracket kit is designed for LS engines used in trucks and SUVs, including LSX and Camaro configurations. It uses a USA-made belt tensioner, bolts, pulley, and bracket to provide a complete installation. This kit is noted for its robust build and straightforward mounting process, supporting a reliable and aligned belt path with the factory or aftermarket drives. It is suitable for builders seeking an all-in-one solution with emphasis on solid American manufacturing.
LS R4 AC Bracket Kit High Mount By TENGBASE
This high-mount bracket focuses on optimal compressor positioning for LS R4 engines, including LSX, LS2, LS3, and LS6 platforms, as well as Vortec-equipped trucks and SUVs. The triangular bracket configuration aims to deliver enhanced stability and better belt alignment, reducing fitment interference with other accessories. It’s positioned as a choice for builders prioritizing space and drivetrain alignment in tighter engine bays.
Wyckoff LS Swap R4 Bracket Kit
Wyckoff’s LS Swap R4 Bracket Kit is designed for LSX/LS2/LS3/LS6 configurations running Vortec drives in Chevy and GMC SUVs and trucks. It emphasizes high-tolerance CNC machining for a precise fit with factory R4 compressors and the associated belt system.

Aosuracing LS R4 Bracket Kit High Mount
Aosuracing offers a high-mount bracket design intended for LSX/LS2/LS3/LS6 and Vortec engine bays. The kit highlights higher-accuracy CNC machining to ensure precise fitment with factory R4 compressors used in LS trucks and Camaro configurations. It emphasizes compatibility with common LS engines (4.8L to 6.2L and LSX blocks) and emphasizes belt path reliability for a clean installation in performance builds.
VVORHSBELL LS A/C Bracket Kit
The VVORHSBELL kit is designed to replace or upgrade LS truck/SUV drives with Sanden 508 or 709 compatibility. It outlines belt length options and the need for an idler relocation when using factory brackets with certain alternator setups. The kit is positioned as a flexible option that supports both basic and more complex belt configurations, making it versatile for various LS engine builds.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Confirm the bracket supports your LS generation (LS1/LS3/LSX) and the compressor model (Sanden 508/709) you plan to use.
- Mounting design: High-mount brackets save space in tight engine bays, but may require careful belt path planning and compatible pulleys.
- Included hardware: Some kits include tensioners, idler pulleys, bolts, and belts, while others require sourcing components separately; verify what comes in the box.
- Material and finish: CNC-machined aluminum brackets offer strength and precision, while billet aluminum options emphasize exact tolerances and reduced flex under load.
- belt length and tension: Ensure compatibility with your belt drive setup, including alternator size and water pump style, to avoid alignment issues.
- Installer considerations: Some kits assume different idler relocations or crank pulley configurations; check notes about required belt sizes and potential modifications.
- Vehicle application: If your build targets a daily driver or a high-performance race application, prioritize a kit with proven fitment for your model year and drive configuration.
In evaluating these five options, builders should balance space, alignment, and ease of installation. For classic LS swaps with tight engine bays, the high-mount designs from TENGBASE and Wyckoff provide strong fitment defaults. If you prefer a complete hardware package, ICT Billet’s kit offers a turnkey approach with included tensioners and pulleys. RiAiCiING and VVORHSBELL emphasize versatility for Sanden compressors with clear notes about belt lengths and idler relocations, which can impact long-term reliability. Each kit has its own installation nuances; refer to product pages for precise belt lengths and compatibility notes before purchasing.
