The accelerator cable is the direct link between your foot and the engine’s power delivery, translating every pedal movement into immediate throttle response. The WG972556571001 ACCERELATOR CABLE(HOWO) from HOWO is engineered to deliver exceptional precision, ultra‑low friction, and long‑lasting reliability, ensuring that your truck responds instantly and smoothly to every driving command. As a vital Howo/Sitrak truck parts component, this accelerator cable is manufactured from high‑strength steel inner wire with a durable, low‑friction outer sheath, providing consistent cable travel and resistance to stretching or binding. Its pre‑formed ends and exact length match the original equipment, guaranteeing a perfect fit without any modifications. Whether you are replacing a worn, sticky cable or performing a full throttle system overhaul, the WG972556571001 delivers factory‑spec performance, smooth pedal action, and dependable service – making it the trusted choice for professional workshops and fleet operators worldwide.
The accelerator cable is responsible for transmitting the driver’s throttle input to the fuel injection pump or electronic throttle actuator. Over time, cables can stretch, corrode, or suffer from internal friction, resulting in a sluggish pedal feel, delayed response, or even sticking – all of which compromise vehicle drivability and safety. The WG972556571001 is specifically designed to overcome these issues with a premium inner wire that is coated for reduced friction and a flexible outer sheath that resists kinking and abrasion. Its exact length and pre‑fitted end terminals ensure that the pedal travel and throttle opening are calibrated to factory specifications, restoring the original crisp response. By using this genuine HOWO cable, you eliminate unpredictable throttle behaviour, improve fuel efficiency through precise control, and extend the life of the throttle linkage components.

The WG972556571001 is built with attention to every detail, from the inner wire to the outer sheath and the end terminals. The inner wire is manufactured from high‑tensile steel with a smooth zinc coating that resists rust and reduces friction, ensuring effortless pedal movement and consistent tension. The outer sheath is a multi‑layer composite – a tough nylon outer cover for abrasion resistance, a braided steel reinforcement for kink protection, and a low‑friction inner liner that allows the wire to glide smoothly even under sharp bends. The end fittings are precision‑formed and securely swaged to the wire, eliminating any possibility of detachment. Each cable is inspected for length tolerance, travel range, and flex resistance, guaranteeing that the WG972556571001 meets HOWO’s strict quality standards. This meticulous engineering ensures that your throttle response remains instant, smooth, and predictable, mile after mile.
The WG972556571001 is specifically designed for HOWO T7H and A7 trucks equipped with MC11 or MC13 engines, as well as many Sinotruk models that use the same throttle control system. It directly replaces the original accelerator cable, with identical mounting points, pedal connection, and injection pump linkage, ensuring a straightforward swap without any modifications. The cable is compatible with both mechanical and electronic throttle systems that employ a cable‑actuated fuel pump.
To confirm fitment, always cross‑reference the OEM number on your existing cable with WG972556571001. If they match, this component will integrate seamlessly. Keeping this cable in your spare parts inventory enables rapid throttle system repairs, minimising downtime and ensuring your engine always responds promptly to driver input.

Replacing a stretched or binding accelerator cable with the WG972556571001 immediately restores the crisp, linear throttle response that modern drivers expect. The low‑friction inner wire and smooth sheath eliminate the “sticky” feeling that often develops in older cables, allowing for precise modulation of engine power – especially important when maneuvering in tight spaces or during delicate throttle applications. The improved response also enhances drivability, making the truck feel more connected and responsive to driver inputs.
The exact length and pre‑set travel range ensure that the full throttle opening is achieved without over‑travel, protecting the fuel pump linkage from stress. Additionally, the corrosion‑resistant materials prevent the cable from seizing in harsh weather, ensuring consistent performance year‑round. For fleet operators, a reliable accelerator cable reduces throttle‑related complaints, improves fuel economy through precise control, and contributes to overall driver satisfaction. By investing in the WG972556571001, you ensure that your HOWO truck delivers the responsive, predictable throttle feel that professional drivers value.
Installing the WG972556571001 Accelerator Cable is a simple procedure. Start by safely securing the vehicle and removing the old cable by disconnecting it from the pedal and the injection pump. Carefully route the new cable along the original path, avoiding sharp edges or hot components that could damage the sheath. Secure the cable with the original retaining clips and adjust the end fittings to achieve the correct free play (typically 2‑3 mm at the pedal). Test the pedal for smooth, full travel and verify that the throttle reaches the stop without binding. Periodically lubricate the cable ends with a light oil and inspect the sheath for wear. With proper installation, the WG972556571001 will provide years of smooth, responsive throttle control.
Pro Tip: When installing the new cable, always check the pedal pivot and throttle linkage for wear – replacing these components along with the cable ensures the entire system operates smoothly. The WG972556571001 is designed to work with OEM linkage; use the specified adjustment procedure for optimal performance.
Genuine HOWO components are engineered to the highest standards, and the WG972556571001 Accelerator Cable is no exception. Aftermarket cables often use inferior steel, poor‑quality sheaths, or inaccurate lengths, leading to premature wear, binding, or even breakage. HOWO’s cable is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance.
By choosing the WG972556571001, you benefit from HOWO’s rigorous testing, including tensile strength, flexibility, and environmental resistance tests. This ensures that the cable meets the demanding requirements of heavy‑duty trucking. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global network, giving you confidence in your purchase.
