maXpeedingrods LS AC Compressor Adapter Fittings for 10S17F/10S20F — Billet Aluminum, Converts to #8AN & #10AN

These maXpeedingrods adapter fittings let you mount 10S17F or 10S20F air conditioning compressors on LS truck-style engines by converting factory ports to #8AN and #10AN lines.

When swapping an LS-series truck engine (LQ4, LQ9, or other 4.8/5.3/6.0 truck engines) into a custom chassis, AC plumbing often becomes the bottleneck. This adapter set provides durable, corrosion-resistant billet-aluminum fittings and the sealing hardware needed to connect modern 10S-series compressors to the original truck accessory ports. It replaces several OEM part numbers and includes the small fasteners and seals required for installation, saving you time hunting down compatible fittings.

Will these adapters fit my LS swap compressor and engine?

These adapters are engineered specifically to allow 10S17F and 10S20F compressors to attach to the accessory ports used on LQ4, LQ9 and many truck-based LS engines. They are not universal; verify your compressor type and drive kit before ordering. Note: they will not work with compressors using the performance #19155066 serpentine drive kit for Chevrolet.

• Compatible compressors: 10S17F and 10S20F models
• Compatible engines: LQ4, LQ9 and most 4.8/5.3/6.0 truck LS engines
• Incompatible with performance #19155066 serpentine drive kit

How do these fittings help install aftermarket AC lines?

The kit converts the OEM truck ports to standard AN hose sizes so you can run modern braided or hard lines without cutting or custom-threading. That simplifies plumbing and reduces leak points compared with improvised adapters. Included sealing washers and O-rings make it straightforward to achieve a proper seal during assembly.

• Outputs converted to #8AN and #10AN hose sizes
• Includes 2 sealing washers and 2 O-rings for leak prevention
• Ships with steel socket head cap screws for secure mounting

What materials and quality controls are used?

Each adapter is CNC-cut from billet aluminum and finished to resist rust and corrosion, giving a stable, long-lasting mating surface between compressor and engine. Welding seams are inspected and tested to help ensure structural integrity under vibration and thermal cycling. The result is a professional-grade fitting intended for repeated assembly and workshop use.

• Material: billet aluminum with protective finish
• Welds tested for strength and leak resistance
• Designed for automotive vibration and heat exposure

What hardware and support are included with the kit?

The package contains the adapter fittings plus the small hardware needed to complete installation so you can avoid sourcing multiple parts separately. For peace of mind, maXpeedingrods provides technical help and a limited warranty should you encounter quality issues. Keep vehicle- and compressor-specific notes handy when contacting support to speed troubleshooting.

• Contents: 1x #8AN fitting, 1x #10AN fitting
• Sealing hardware: 2 sealing washers, 2 O-rings
• Mounting hardware: 2 steel socket head cap screws
• Support: lifetime technical support, 1-year limited warranty

Who is this for: This adapter kit is aimed at mechanics, hot-rodders and professional shops performing LS truck engine swaps that want to install a 10S17F or 10S20F compressor without extensive custom plumbing. It suits anyone who prefers durable billet components, complete sealing hardware out of the box, and access to post-purchase technical support. If your compressor uses the Chevrolet performance #19155066 serpentine kit, choose a different solution.
