High-torque driveline-optimized commercial trucks engineered for harsh mining, regional transport, and infrastructure development.
In modern industrial logistics, heavy commercial transport, and high-load fleet management, drivetrain efficiency dictates bottom-line profitability. Specifically, the valvetrain of commercial transport vehicles—such as the widely deployed Sinotruk HOWO and Shacman F3000 platforms—determines the engine's peak volumetric efficiency, thermal limits, and fuel combustion efficiency. This is where customized, CE-certified LS Truck Cam (Long-Stroke/Low-Speed Truck optimized Camshaft profiles) upgrades step in.
At our advanced engineering and manufacturing base in Chengdu, Sichuan, we focus on producing precision camshaft profiles engineered to shift the torque curve downward. This design ensures that heavy-duty trucks generate peak torque in the lower RPM ranges (1,000–1,400 RPM). By modifying lift, duration, and lobe separation angles, our LS Truck Cam setups allow loaded tractor units and tipper dump trucks to maintain momentum on steep gradients without excessive fuel wastage.
Our commitment to global standards is validated by strict CE Certification, guaranteeing that every camshaft, valvetrain upgrade, and heavy-duty commercial vehicle leaving our facilities meets rigorous European environmental, health, and mechanical safety benchmarks.
Providing heavy-duty fleet solutions that address global supply chain constraints, localized compliance, and rugged operating environments.
For mining and civil construction projects globally—particularly in harsh terrains across Africa and Central Asia—standard drivetrains often struggle. Our CE certified LS Truck Camshaft upgrades boost low-end traction, reducing clutch wear and drivetrain fatigue under heavy payloads.
Global logistics managers face tightening emissions standards. Upgrading to a optimized camshaft profile improves air-fuel mixture quality, lowers emissions profiles, and guarantees that older engines (Euro 3/4) meet localized compliance directives when imported.
By optimizing valve lift velocity and duration patterns, fleets experience up to a 4.5% improvement in overall fuel efficiency. Scaled across a fleet of 50 or 100 heavy-duty dump trucks, this optimization yields significant annual operational savings.
Leveraging state-of-the-art testing centers and large-scale manufacturing infrastructure in Chengdu and Deyang, China.
At present, our corporate headquarters is situated in Shundi Auto Trade City, Deyang City, featuring a modernized administrative office complex covering an area of 15,000 square meters. In tandem with this administrative facility, we operate our own specialized commercial vehicle and drivetrain components testing center and refurbishing factory.
The evolutionary path of Hongkai Automobile Trading Co., Ltd. from a local distributor to an international commercial vehicle solutions builder.
Entered the field of heavy truck sales, gaining hands-on mechanical experience with heavy diesel powertrains and studying heavy-duty truck requirements in China's domestic transport sectors.
Established a partner sales framework, launching integrated "financial leasing + comprehensive maintenance and fleet trusteeship" packages, covering key logistics hubs across six provinces in South China.
Founded the core company in Deyang City, Sichuan Province. Focused initially on the premium heavy truck market in China, establishing a robust local customer base and building out a structured procurement-modification-certification-after-sales workflow.
Constructed the 20,000 square meter Hongkai Automobile Trade City. Successfully generated annual sales revenues exceeding 50 million yuan. Solidified official distribution partnerships for premium Chinese brands including Sinotruk HOWO, Dongfeng, Jiefang, and Shacman.
Deployed our first internal logistics fleet consisting of 100+ smart heavy-duty trucks. This service reduced regional parts shipping delivery windows across South China by 70%.
Management launched our globalization initiative, expanding export footprints into Africa, the Middle East, and Central Asia. In 2023, built our primary Chengdu plant and upgraded our commercial truck remanufacturing capabilities to meet strict CE standards.
Scaled international sales models combining digital support with physical service hubs, strengthening trade links with overseas logistics operations and mining fleets.
How our factory guarantees mechanical compliance and safety benchmarks for heavy-duty components.
Every LS Truck Camshaft produced in our Chengdu factory undergoes a rigorous Quality Assurance (QA) protocol. CE Certification represents compliance with European directives for machinery safety, structural integrity, and environmental standards. For heavy-duty drivetrains, compliance requires:
Our testing facility runs endurance simulations on our powertrains, verifying that all engine components function safely under extreme operational heat loads.
Why fleet operators and industrial procurement teams choose Hongkai as their heavy-duty equipment partner.
Our long history in the commercial truck industry gives us deep insight into fleet requirements, regional regulations, and mechanical optimization. We provide targeted drivetrain modifications that ensure long-term equipment reliability.
We work with clients from initial requirements analysis to custom component design. Whether you require custom camshaft lobes for high-altitude operations or specific tipper body structures, we tailor solutions to match your operating environments.
Our service framework spans pre-sales consulting, technical implementation, and after-sales support. We provide 7×24 technical support to address maintenance needs, keep your vehicles running, and minimize operational downtime.
We host procurement delegations and technical inspectors from Africa, Central Asia, and the Middle East, verifying our production standards and vehicle readiness.
Common questions from global procurement managers regarding LS truck camshafts, compliance, and international shipping.
The LS (Low-Speed/Long-Stroke) optimized camshaft configuration focuses on enhancing low-to-mid range torque. By increasing exhaust gas velocity and optimizing valve timing overlaps, it allows heavy-duty diesel engines, like the WD615 or WP10/WP12, to carry heavy payloads over steep grades without constantly shifting gears. This reduces clutch wear, lowers transmission strain, and improves fuel economy by 3% to 5%.
CE Certification verifies that our vehicles and aftermarket components meet European safety, health, and environmental standards. For industrial fleets, this certification facilitates customs clearance in regions that align with EU standards, assures safety compliance, and verifies that the structural materials used can withstand demanding operational environments.
Our refurbishment process involves systematic disassembly, inspection, and component replacement. Engines undergo dynamometer testing to verify compression and cylinder balance, while transmission systems receive fresh synchronizers and gears. Every vehicle undergoes a multi-point inspection at our Chengdu testing center prior to dispatch, ensuring it meets our operating standards.
We offer comprehensive customization options, including steel thickness upgrades for tipper cargo boxes, reinforced leaf spring suspensions, dual-layer chassis structures, heavy-duty air filtration setups for dusty mine sites, and left-hand or right-hand drive conversions to match regional traffic regulations.
We offer various shipping terms, including FOB, CIF, and CFR, using both Roll-on/Roll-off (Ro-Ro) and container shipping. For after-sales support, we supply replacement parts catalogs, provide 24/7 technical consulting, and maintain replacement parts inventories at strategic shipping points to ensure prompt maintenance support.
