The Right rear bracket of front spring is the right‑side counterpart of the left rear bracket[reference:28]. It supports the rear end of the right leaf spring, connecting the shackle to the chassis frame for balanced suspension support.
The Right front spring pressure plate is the right‑side counterpart of the left pressure plate. It distributes the U‑bolt clamping force evenly across the right leaf spring pack, ensuring proper spring function and longevity.
The Right front bracket of front spring supports the front end of the right leaf spring. It provides a secure mounting point for the spring eye and transfers the vehicle’s weight from the spring to the chassis frame.
The Front bracket of front spring is a universal bracket that supports the front end of the leaf spring assembly[reference:29]. It connects the spring eye to the chassis frame, providing a pivot point for the spring as it flexes[reference:30].
This lock nut features a toothed flange that bites into the mating surface, providing a vibration‑proof connection[reference:31]. Its M16*1.5 fine thread ensures secure fastening for critical suspension joints in the Front suspension system.

The robust brackets and cross beams maintain proper axle alignment, reducing tire wear and improving handling[reference:36].
The use of high‑grade steel and corrosion‑resistant coatings in the Front suspension extends the life of each component, even in harsh climates. The precision‑machined spring pins and bushings ensure smooth, quiet operation over millions of cycles[reference:37]. The grease nipples allow for regular lubrication, reducing wear and tear[reference:38].
The Front suspension kit is also designed with serviceability in mind – all fasteners are accessible, and the modular nature allows for individual component replacement if needed[reference:39]. This reduces downtime and maintenance costs for fleet operators, making the Front suspension a smart investment for any HOWO 4X2.
Every Front suspension component is subject to stringent quality inspections. Brackets are checked for dimensional accuracy and weld integrity. Leaf springs are tested for load capacity and fatigue resistance. Fasteners are sampled for tensile strength and thread quality, and U‑bolts are verified for proper clamping force.
We also perform assembly tests on complete Front suspension kits, simulating real‑world load and vibration conditions. Thermal cycling tests validate the durability of rubber and polyurethane components. These guarantees ensure that the Front suspension delivers consistent, reliable performance throughout its service life.
Our quality management system is certified to IATF 16949, and each kit is traceable to its production batch, providing full accountability and rapid resolution of any issues.
