Located in Foshan, Guangdong, Southern China, Guangdong GAP Auto Parts Co., Ltd. (GAPASA) is an IATF 16949-certified commercial vehicle brake parts manufacturer with more than 20 years of industry experience. We manufacture truck and trailer brake components for distributors, importers, aftermarket brands and OEM customers across international markets.
Our core product range includes brake chambers and slack adjusters, supported by S-camshafts and other essential components used in commercial vehicle air brake and drum brake systems. GAPASA supplies service brake chambers, spring brake chambers, automatic slack adjusters, manual slack adjusters and application-specific replacement parts for trucks, trailers, buses and heavy-duty vehicle platforms. Our team also provides OEM number matching, product identification and specification support to help professional buyers source the correct components for their target markets.
GAPASA’s manufacturing facility combines forging, casting, CNC machining, rubber and plastic molding, component assembly and product testing. By managing key production processes in-house, we can maintain closer control over product dimensions, materials, component compatibility and production consistency. Inspection is carried out throughout the manufacturing process, from incoming materials and in-process dimensional checks to assembly verification and final functional testing.
Our engineering and quality teams work together to review drawings, samples, technical specifications and application requirements. This enables GAPASA to support both standard aftermarket supply and customer-specific projects, including private-label products, customized packaging, specification adjustments and new product development. Production and inspection records also support batch-level traceability and more efficient quality follow-up.
As an experienced brake chamber and slack adjuster manufacturer, GAPASA understands that B2B customers need more than a broad product catalogue. Reliable cooperation also depends on consistent repeat-order quality, accurate product data, responsive communication and clear commercial terms. Our sales and technical teams support customers with reference-number confirmation, drawings, product documentation, sample enquiries, order planning and export coordination.
GAPASA serves commercial vehicle parts distributors, truck and trailer parts importers, aftermarket brake brands, repair networks and OEM buyers worldwide. Whether customers require standard replacement models, mixed-product orders, private-label supply or components developed from drawings and samples, we aim to provide practical manufacturing and sourcing support throughout the project.
Our goal is to build long-term partnerships by delivering dependable commercial vehicle brake components, transparent communication and stable international supply. As GAPASA continues to expand its brake chamber, slack adjuster and truck brake parts range, we remain focused on manufacturing control, product development and responsive B2B service.
