RiAiCiING LS Engine Serpentine Bracket Overview
Best for: LS swap builders needing a simple, durable relocation that rotates the alternator 180 degrees. This kit is designed to push the power steering pump up or in while clearing bulky factory brackets, enabling multiple intake manifold configurations.
Why selected: It uses high-quality aluminum alloy with an anodized black surface for corrosion resistance and durability. Its broad compatibility includes LS1/LS2/LS3/LS6 variants and common 4.8L–6.2L engines found in truck and SUV platforms.
Limitation: The description notes compatibility with many LS variants, but exact belt-length compatibility isn’t detailed in the listing. Confirm belt length with your specific engine setup before ordering.
Bevinsee LS Engine Serpentine Bracket
Best for: Builders who want installation flexibility, including two common methods shown in product images. Suitable for GM LS1/LS2/LS3/LS6/LS7 engines ranges (4.8L–6.2L) in trucks and older cars.
Why selected: It includes an instruction manual and clarifies belt-length considerations due to variations in winding methods and bracketing design. The bracket aims to reduce frame width and engine bay clutter.
Caution: Belt length compatibility may vary by wind method and bracket composition; verify fitment against your belt setup and tensioner before purchase.
ICT Billet LS Truck Driver Side Bracket
Best for: Drivers requiring the alternator to sit higher and more forward, enabling easier belt routing or adding clearance for hoses and lines.
Why selected: Made in the USA from billet aluminum, designed to move the alternator out and down while bringing the power steering pump inward, improving belt alignment in many LS swaps.
Limitation: For Corvette/CTSV or some Camaro large-bolt-pattern alternators, this specific driver-side kit may not fit; verify compatibility with your alternator model before purchase.
ICT Billet LS Truck Bracket With Idler Pulley
Best for: DIYers seeking a complete kit with both front and rear idler pulleys and mounting hardware for a clean swap.
Why selected: This kit emphasizes a broad compatibility range and assembly-ready design, highlighting USA-made billet aluminum construction and included mounting components.
Limitation: The product notes require matching with the correct crank pulley and LS engine configuration; validate your engine particulars to ensure full compatibility.
RJSPHH LS Engine Serpentine Bracket (Black)
Best for: Chevrolet LS1–LS2–LS3–LS6–LS7 engine swaps needing improved power steering pump placement and a tighter serpentine system with organized routing.
Why selected: The design pushes the power steering pump forward and rotates the alternator 180 degrees, aiding compatibility with multiple LS intake manifolds while maintaining a cleaner belt layout.
Limitation: Availability may vary; ensure the listing supports your exact engine and accessory layout to avoid fitment issues.

Best for: LS-powered trucks wanting to relocate the OEM-style bracket with a robust aluminum build and OEM-like fit for LS3/L99 configurations.
Why selected: It supports standard and high-output alternators and is designed for compatible LQ4/LQ9/LY5 engine families, with a focus on maintaining reliable mounting points.
Limitation: It mentions 105 Amp and 145/160 Amp alternator support; verify your specific amperage requirements to ensure fit and heat considerations are appropriate.
Buying Guide
What to consider when choosing an LS truck alternator bracket
- Engine compatibility: Confirm the bracket supports your LS family (LS1, LS2, LS3, LS6, LS7, LQ4, LQ9, LY5, etc.) and your displacement (4.8L–6.2L).
- Mounting position: Decide between high-mount vs. driver-side relocation, based on frame clearance, radiator/backing, and belt tensioner availability.
- Material and finish: Aluminum brackets with anodized coatings resist corrosion and heat; billet aluminum options offer precise tolerances.
- Included hardware: Some brackets include idler pulleys and mounting hardware; others require separate purchases—check every component you’ll need.
- Installation method: Look for manuals or clearly described installation approaches; two common methods may require different belt lengths.
- A/C and accessory compatibility: Ensure the bracket positions accommodate an A/C compressor or other accessories without interference.
- Warranty and support: When available, prefer brands with clear support for installation questions or fitment concerns.
FAQ
What is the main purpose of an LS truck alternator bracket?
To relocate the alternator and/or power steering pump for better belt routing, reduced clutter, and improved clearance in LS-based swaps.
Do these brackets fit all LS engines?
Most are designed for common LS families (LS1, LS2, LS3, LS6, LS7) and engine sizes (4.8L–6.2L). Always check the product notes for specific compatibility.
Should I choose high-mount or driver-side relocation?
High-mount relocations free space near the valve cover, while driver-side relocations optimize engine bay clearance and belt routing in tight builds.
Do brackets include pulleys and hardware?
Some kits include idlers and mounting hardware; others require separate items. Review product features carefully before purchase.
Is aluminum the best material for these brackets?
Aluminum offers light weight, strength, and corrosion resistance, with billet options providing tighter tolerances for precise alignment.
