As a GM Car Camshaft Suppliers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
As a dedicated Wholesale GM Car Camshaft Company, Anhui KORBOR Machinery Co., Ltd. specializes in the design, casting, machining, and finishing of camshafts for General Motors engines. With over 25 years of focused camshaft manufacturing, we supply a comprehensive range of GM camshafts for passenger cars, light trucks, and performance applications, serving distributors, engine rebuilders, and OEM-tier customers worldwide.
Our factory in Susong Economic Development Zone spans 28,000 square meters and houses our own foundry, CNC machining lines, heat treatment facilities, and metrology lab. This vertical integration allows us to control quality from raw material to finished product, ensuring consistent dimensional accuracy and metallurgical integrity across every batch.
We manufacture camshafts for a wide array of GM engine families, including Ecotec, Small Block, LS, LT, and Vortec series. Our catalog includes both OEM replacement and performance profiles, each engineered to match the original lobe specifications or your custom grind requirements.
| Engine Family | Typical Applications | Available Configurations |
|---|---|---|
| Ecotec (1.4L, 1.5L, 1.6L, 2.0L, 2.4L) | Chevrolet Cruze, Malibu, Equinox; Buick Encore, Verano | DOHC, VVT, roller follower profiles |
| Small Block (Gen I, Gen II) | Chevrolet Camaro, Corvette, Silverado; GMC Sierra | OHV, hydraulic roller, flat tappet |
| LS/LT (Gen III, Gen IV, Gen V) | Performance and truck applications | High-lift, wide-lobe, VVT compatible |
| Vortec (4.3L, 5.0L, 5.7L, 6.0L) | Chevrolet Express, Avalanche; GMC Savana | OE replacement, heavy-duty |
Each camshaft is machined from high-performance alloy steel or cast iron, depending on the application, and undergoes heat treatment processes such as carburizing, quenching, and tempering to achieve the required surface hardness and wear resistance.
Our R&D team works from your drawings, samples, or performance targets to develop camshafts that meet specific lift, duration, and lobe separation angle requirements. We support both reverse engineering and original design, ensuring that the cam profile matches your engine's valve train geometry and operating range.
For high-volume programs, we offer design-for-manufacturing support to optimize the camshaft for cost-effective production without compromising performance.
We follow the IATF 16949:2016 quality management system and maintain a “zero defect” philosophy. Every production stage—from incoming material inspection to final dimensional verification—is controlled with documented procedures.
Our in-house laboratory is equipped with advanced testing equipment to verify metallurgical properties and ensure consistency across production batches.
With annual output exceeding 2.3 million camshafts, we can accommodate orders ranging from small batch prototypes to high-volume production runs. Our location in Anhui provides convenient access to Ningbo and Shanghai ports, ensuring efficient export logistics.
We maintain a buffer stock of popular GM models to support urgent replenishment, while custom orders are scheduled based on your forecast and lead time requirements.
To prepare an accurate quotation and manufacturing plan, we need the following details from your side:
| Parameter | Why It Matters |
|---|---|
| OE part number or engine code | Identifies the exact camshaft specification |
| Application (vehicle model, year, engine) | Ensures correct valve timing and fitment |
| Performance requirements (if custom) | Defines lobe profile and material selection |
| Annual volume and order frequency | Determines production scheduling and pricing |
| Packaging and marking preferences | Aligns with your warehousing and distribution needs |
