maXpeedingrods AC compressor adapter fittings for 10S17F/10S20F — billet aluminum, #8AN & #10AN kit

These maXpeedingrods adapter fittings let you mount a 10S17F or 10S20F air conditioning compressor to LS-series truck accessory locations quickly and reliably.

When swapping an LS engine into a vehicle that originally used truck accessories, getting the AC system to mate up can be a tricky alignment problem. These adapter fittings are machined from billet aluminum to bridge the hose and port differences so you can use common 10S-series compressors on LQ4, LQ9 and most 4.8/5.3/6.0 truck-pattern LS engines. The kit arrives with the fasteners and seals you need to finish an install and includes lifetime technical support plus a one-year limited warranty for manufacturing defects.

How will these adapters simplify my LS engine AC installation?

The adapters convert factory truck-style ports to the AN fittings used on many 10S compressors, eliminating custom hoses or time-consuming fabrication. They shorten installation time and reduce the risk of leaks by supplying correct-size fittings and the required O-rings and sealing washers.

• Includes #8AN and #10AN fittings for direct hose attachment
• Supplied O-rings and sealing washers for leak-free connections
• Socket head cap screws provided to secure the fittings to the compressor

Will these work with every 10S compressor and LS engine?

They are compatible with most 10S17F and 10S20F compressors and designed to match truck-pattern LS accessories including LQ4 and LQ9. However, they are not compatible with compressors using the Chevrolet performance serpentine drive kit part #19155066, so confirm your compressor part numbers before purchase.

• Fits 10S17F and 10S20F style compressors
• Targets LQ4, LQ9 and similar truck accessory patterns
• Not compatible with performance serpentine kit #19155066

What materials and quality checks were used in manufacturing?

Each adapter is CNC-machined from billet aluminum for strength, light weight and corrosion resistance. Weld seams are inspected and assemblies are finished to resist rust, ensuring durability in engine bay conditions.

• Billet aluminum construction for rigidity and longevity
• Quality finish to help prevent corrosion and surface wear
• Welds tested and inspected before shipping

What hardware and support come with the kit?

The package contains all small parts needed to complete the retrofit so you won’t need to source specialty hardware. maXpeedingrods also offers lifetime technical support and backs the product with a one-year limited warranty covering manufacturing quality issues from purchase date.

• 1x #8AN fitting and 1x #10AN fitting included
• 2 sealing washers, 2 O-rings, and 2 steel socket-head cap screws
• Lifetime tech support and 1-year limited warranty

Who is this for: This adapter set is intended for mechanics, custom car builders and DIY enthusiasts doing LS swaps who want to reuse 10S-series AC compressors on truck-pattern LS engines. It’s best for projects where minimizing fabrication and ensuring proper sealing are priorities; confirm compressor compatibility before ordering to avoid mismatches with certain performance drive kits.
