Esslinger Engineering

What Esslinger Engineering does

Esslinger Engineering Inc., operating commercially as Esslinger Racing, is a Chino, California-based e-commerce retailer and engine builder founded in 1967 that specializes in high-performance parts and engines for Ford four-cylinder engines (SOHC "Lima," Duratec, Ecoboost, Coyote), Mazda MZR/DISI engines, and proprietary Esslinger Midget racing engines. The company's core technology is the in-house specification, assembly, and tuning of race engines using OEM blocks machined and built by its own technicians, with proprietary "Esslinger-spec" components co-developed with manufacturing partners such as Racetec, JE Pistons, and Manley. Documented capabilities include methanol-burning midget engines revving to 10,400 rpm and ultra-lite 2.3L shortblocks rated to 9,500 rpm, alongside documented Engine Recipes spanning multiple platforms.

Revenue is generated through three streams. The largest is direct-to-consumer e-commerce parts sales via esslingeracing.com, offering individual components (pistons, rods, bearings, gaskets, sensors, fasteners) at unit prices ranging from $11.55 to $2,859.99. The second stream is the sale of assembled shortblocks and complete engines at $4,199-$5,999 for standard stages with custom builds available. The third is a pay-per-session remote ECU tuning service at $24.99 per tune. Customers are primarily midget racing teams, circle-track racers, and performance engine builders, with newer exposure to UTV/desert racing enthusiasts via a Polaris Pro-R exhaust line. The business operates from a single headquarters at 5946 Freedom Dr, Chino, CA with a staff in the 11-50 range, serving North American customers via direct e-commerce with no dealer network.

• CP-Carrillo: Manufacturer of high-performance pistons and connecting rods for motorsport and racing applications. Direct peer because both supply the same engine builder customers focused on high-RPM, durability-critical racing engines.
• COMP Cams: Manufacturer of camshafts, valvetrain, and engine building components for performance and racing applications. Direct peer because both serve engine builders assembling high-performance Ford and racing engines with overlapping valvetrain and camshaft product categories.
• Racetec Pistons: Custom forged piston manufacturer for racing and performance engines. Direct peer because Esslinger co-specs custom Racetec pistons (5.7" rod, specific compression heights) for its Ford SOHC shortblocks, competing for the same high-RPM racing engine builder segment.
• Trick Flow Specialties: Manufacturer of high-performance cylinder heads, intake manifolds, and camshafts for Ford engines. Direct peer because both compete in the Ford performance aftermarket, including Ford 4-cylinder and modular V8 platforms that overlap with Esslinger's Coyote V-8 line.
• Total Seal: Piston ring manufacturer specializing in gapless and low-friction ring technologies for racing. Direct peer because Esslinger resells Total Seal products as a brand partner for the same engine builder customers building high-RPM race engines.
• K1 Technologies: Manufacturer of connecting rods, pistons, and crankshafts for performance and racing engines. Direct peer as a competing boutique performance engine component maker serving the same Ford 4-cylinder and modular engine builder market.

Broad incumbents

• Holley Performance: Diversified performance products company offering carburetors, fuel systems, ECUs, and exhaust across multiple racing and street performance segments. Broad incumbent with significant Ford and modular V8 presence; competes with Esslinger on ECU/electronics resale and broader engine build categories.
• Edelbrock: Large, established manufacturer of performance intake manifolds, cylinder heads, and supercharger systems for V8 American performance engines. Broad incumbent with overlapping performance aftermarket customers, but does not specialize in 4-cylinder Ford racing engines like Esslinger does.
