RJSPHH LS Serpentine Bracket

This bracket is designed for Chevrolet LS1, LS2, LS3, LS6, and LS7 engines plus 4.8L–6.2L truck and SUV platforms. The feature set centers on tightening the power steering pump placement and organizing a cleaner serpentine system. It pushes the power steering pump upward and inward while rotating the alternator 180°, expanding compatibility with various intake manifolds. Best for builders seeking a compact, cleaner engine bay without sacrificing alignment. A potential limitation is that fitment can vary with aftermarket accessories, so verify clearance with your specific setup.

Best for: Small to mid-length engine bays where belt alignment is critical and space needs to be optimized.

What to watch: Confirm compatibility with your current intake manifold and ensure the 180° rotated alternator does not interfere with nearby components.

ICT Billet LS Truck OEM Location Bracket

ICT Billet’s bracket is marketed for truck/SUV use and LS3/L99 Camaro crank pulley configurations. It is crafted in Wichita, Kansas from aerospace-grade billet aluminum and is compatible with a Saginaw Type 1 power steering pump. The premium materials and USA production appeal to builders prioritizing rigidity and precise finish. The bracket is a solid choice where OEM-style placement and high-end construction matter. A practical caveat is that some vehicle combinations may require additional belt-length adjustments depending on pulley setup.

Best for: Builders who want a sturdy, factory-like relocation solution with high-precision machining.

What to watch: Check belt length requirements for your exact pump and pulley configuration; some installations may need minor tweaks.

RiAiCiING LS Truck OEM Location Bracket

This RiAiCiING bracket targets LS-powered truck and LS3/LS99 configurations with LQ4/LQ9 engines. It supports a Saginaw Type 1 power steering pump and is compatible with various alternator amperages (105A to 160A). The bracket is machined from aviation-grade 6061 aluminum with anodized black finish for corrosion resistance and durability. It offers a balance of strength and lighter weight, with stainless steel bolts included. A limitation is that some aftermarket headers or exhaust components could affect belt alignment in tight engine bays.

Best for: Versatile, high-durability swaps where multiple alternator options may be used.

What to watch: Ensure compatibility with your specific antenna or sensor placements and verify space for belt routing in your build.

RiAiCiING LS Engine Serpentine Bracket For Swap

This RiAiCiING kit is designed for LS1/LS2/LS3/LS6/LS7, including 4.8L–6.2L engines. It enables a 180° rotated alternator and an elevated/relocated power steering pump, allowing multiple LS intake manifold configurations and removing bulky factory brackets. The kit emphasizes compatibility with LS truck and car setups, offering a robust, all-aluminum construction. A potential drawback is that detailed installation may require precise torque and alignment steps to prevent belt misalignment across different pulley schemes.

Best for: Broad compatibility with multiple LS platforms and manifolds.

What to watch: Follow installation instructions carefully to avoid misalignment; some users may need a belt length check for their specific engine combo.

Bevinsee LS Engine Serpentine Bracket

Bevinsee offers an LS serpentine bracket suitable for Chevrolet LS1/LS2/LS3/LS6/LS7 engines and 4.8L–6.2L variants. It comes with an installation manual (digital version available if missing) and notes two common installation methods. It’s aimed at broad general-purpose swaps, with the goal of reducing engine-width constraints. The note about belt length limitations underscores a practical planning step. This option suits builders who want flexible install approaches and clear installation guidance.

Best for: General purpose swaps where installation flexibility and documentation matter.

What to watch: Belt length may vary with your specific pulling setup; verify tensioner compatibility for your belt path.

Buying Guide: Key Considerations For LS Bracket Swaps

• Vehicle fit: Confirm compatibility with your exact LS engine family and truck/SUV platform. Some brackets are tailored for OEM-like fits, others for maximal space in tight engine bays.
• Pump rotation and belt routing: If relocating the power steering pump or rotating the alternator, check for adequate clearance with pulleys, headers, and intake manifolds.
• Material and finish: Billet aluminum with anodized finishes offer strength and corrosion resistance; consider this for durability in harsh environments.
• Installation documentation: Manually or digital guides help, especially where two installation methods exist. Clear instructions reduce misalignment risk.
• Pulley compatibility: Ensure the bracket supports your current or planned alternator amperage and crank pulley setup to avoid belt slip.
• Maintenance and service: Consider ease of access for future belt changes and tensioning, especially in tight spaces.
• Warranty and origin: USA-made, CNC-machined brackets are often preferred for consistent tolerances, but verify any warranty details from the seller.

FAQ

• Which bracket is best for a tight engine bay? The RJSPHH bracket is designed to push the PS pump and rotate the alternator for better clearance in tight spaces.
• Do these brackets require special installation tools? Basic hand tools are typically sufficient, but some kits include specialized bolts or tensioners; follow the included guide.
• Will these fit LS engines with aftermarket headers? Fit depends on the header design and belt path. Check for header clearance and belt routing compatibility.
