AZ9631521177 HOWO Torque Rod Bushing

This is a spherical pin assembly (V‑push torque rod bushing) for HOWO heavy‑duty trucks, a key part of the driving system. It acts as rubber‑metal suspension component to buffer vibration and stabilize rear axle position, keeping good wheel tracking and preventing abnormal tire wear. Made of tough rubber‑metal integrated materials, it maintains stable performance under heavy‑load and bumpy‑road conditions. It meets OEM standards perfectly, durable and easy to install, a reliable replacement part for HOWO, A7 and related heavy‑duty truck models.

① Applicable Vehicles: Fits HOWO heavy‑duty trucks, mainly for rear axle V‑type torque rod, also compatible with matching heavy‑duty commercial vehicles with same suspension structure.

② Adaptable System: Works seamlessly with factory‑original driving & suspension components. Matches stock V‑push torque rod, rear axle mounting positions exactly for direct bolt‑on replacement, no cutting, drilling or modifications required.

③ OE Reference Number: AZ9631521177

④ Interchangeability: Manufactured to OEM exact dimensions, including outer diameter, inner hole size and mounting interface. Direct swap with original parts, quick to install and remove, cutting maintenance time and labor costs.

⑤ Value‑added Service: We verify compatibility by checking your truck model, axle type and VIN code. We also provide hands‑on guidance for installation, pretension check and routine inspection, helping avoid premature damage caused by improper assembly.

We craft this spherical pin assembly with high‑strength carbon steel core and anti‑aging reinforced rubber body. It withstands continuous torsion, impact and chassis vibration, and resists rubber aging over time. Even under long‑term alternating load, it delivers stable buffering performance without deformation, cracking or loosening. The bonding interface between metal and rubber is specially treated to avoid peeling under heavy stress. Precision machined metal inner sleeve ensures tight fit for mounting bolts, while outer rubber layer absorbs road shock. Built to last in harsh under‑truck chassis conditions, it handles frequent heavy‑load transportation and rough‑road vibration well, restraining rear axle offset and reducing chassis abnormal noise.

The metal inner and outer sleeves are precision‑machined for accurate dimension tolerance. Metal parts adopt anti‑rust surface treatment to avoid corrosion from mud, water and dust. Rubber compound is formulated for anti‑aging and oil‑resistant performance. It performs steadily in dusty, muddy and high‑vibration chassis conditions, resisting rubber hardening, cracking and functional failure even after long‑term service.

We adopt mature vulcanization and metal‑rubber bonding technology to make the spherical pin assembly sturdy and long‑lasting. All key sizes are strictly controlled during production, ensuring a perfect fit with original installation interfaces. Every finished unit goes through strict inspections: bonding strength test, compression fatigue test and dimension inspection. Each batch is fully screened to filter out defective goods. We follow original factory production standards closely, so our parts match OEM performance and durability completely.

We operate mature production lines and professional testing equipment. Our steady monthly output and abundant stock are more than enough to support wholesale and large export orders. We also provide custom processing for size, interface and specifications, along with sample support, to meet the purchasing needs of dealers, repair shops and vehicle manufacturers.

Q: What makes this spherical pin assembly outperform regular alternatives?

A: Built with high‑strength steel core and high‑quality vulcanized rubber, it is far more durable than ordinary torque rod bushings. It stands up to torsion shock, chassis vibration and long‑term wear, resisting rubber cracking, metal‑rubber separation and axle offset. Precision sizing ensures snug fit, effectively reduces chassis noise and prevents abnormal tire wear.

Q: Is the quality reliable? How long can it last?

A: Every unit is manufactured to OEM standards and individually tested for bonding strength and compression fatigue. With strong shock resistance and anti‑aging properties, it typically lasts 2‑3 years under proper maintenance, ideal for long‑haul transport and heavy‑duty daily use.

Q: What advantages will I get after the replacement?

A: It restores original suspension buffering performance, stabilizes rear axle position. It fixes common issues such as loose V‑push rod, chassis knocking noise and irregular tire wear, protects related suspension components and cuts future maintenance costs. It also improves driving stability and overall truck safety.
