Recent moves6 records

Expansion highlights5 records

Direct peers

• Modern Muscle Performance: Direct competitor in the late-model Dodge/Chrysler HEMI performance parts space, selling supercharger systems, ported heads, and engine builds targeting the same Challenger/Charger/300 enthusiast customer. Highly comparable product mix and DTC e-commerce model.
• Edelbrock: Aftermarket performance parts manufacturer selling intake manifolds, supercharger systems, and crate engines. Arrington is an authorized dealer for Edelbrock superchargers, and Edelbrock's portfolio of forced-induction kits for V8 platforms is directly comparable.
• Magnuson Superchargers: Roots-style and centrifugal supercharger manufacturer; Arrington co-developed the Hi-Power kit with Magnuson using Eaton TVS rotors. Overlapping supercharger and engine-building customer base in the late-model V8 market.
• Whipple Superchargers: Twin-screw supercharger specialist; Arrington has been an authorized Whipple dealer since 1987 and the only known shop fitting multiple Whipple 4.0L units to high-power HEMI engines. Directly comparable forced-indiation portfolio.
• ProCharger: Centrifugal supercharger manufacturer; Arrington is an authorized ProCharger dealer. Both serve the same HEMI forced-induction buyer with bolt-on supercharger systems and supporting fuel/tune packages.
• COMP Cams: Major aftermarket camshaft and valvetrain manufacturer whose products frequently appear inside Arrington engine builds. Comparable in camshaft engineering and street/race valvetrain solutions for V8 enthusiasts.

Broad incumbents

• Summit Racing Equipment: Largest U.S. mail-order/online retailer of performance parts across all ICE platforms including HEMI. Comparable DTC e-commerce distribution model and a broad multi-brand catalog, but operates at significantly larger scale and breadth than Arrington's HEMI-focused niche.
• Holley Performance Products: Public performance-products platform (Holley/MSD/Speedmaster/etc.) covering EFI, intake manifolds, and crate engine-adjacent components. Overlaps with Arrington on performance parts and aftermarket induction but at much broader portfolio scale.
• Dodge Direct Connection: OEM-backed factory performance parts and crate engine program for modern Mopar vehicles. Sells Mopar Crate Engines and stage kits directly, increasingly competing with independent shops like Arrington on warranty-backed performance upgrades.

Regional players

• Kooks Headers & Exhaust: Aftermarket header and exhaust manufacturer for late-model American V8s including HEMI applications. Comparable in selling long-tube headers, cat-backs, and emissions-legal exhaust upgrades to the same Dodge/Chrysler performance segment.
