Commercial Vehicle Chassis Parts | Leaf Spring, Hydraulic Pipes & NEV Systems
A leaf spring is one of the most common elastic suspension components in commercial vehicles and some off-road vehicles. It is composed of multiple stacked alloy spring steel leaves of varying lengths and curvatures. It supports vehicle loads through its arched laminated structure and absorbs shocks via friction between the leaves. With strong load-bearing capacity, simple structure and low maintenance cost, it is widely used in trucks, semi-trailers and construction machinery, serving as a core component of heavy-duty vehicle chassis.
Trucks and semi-trailers often carry heavy loads on rough roads, which puts high demands on chassis load-bearing parts.
This leaf spring is assembled with stacked steel plates and mounted closely on vehicle chassis. It eases vibration during driving and bears the whole vehicle weight steadily.
Made of thick solid steel, it hardly deforms or breaks under heavy load and frequent jolts. The tight overlapping structure brings reliable shock absorption performance.
It takes up relatively large space, so installation is not easy for vehicles with narrow chassis space.
It fits all heavy-duty commercial vehicles used for long-distance transportation and construction site work.
For electric trucks and heavy-duty vehicles working on construction sites, the battery compartment under the chassis is the most vulnerable part to impacts and water damage.
Our battery compartment cover fits tightly over the chassis battery pack.
Made of thick steel plate, it won't dent easily even when hitting rocks on rough roads. The rubber seals are pressed tight for water and dust resistance.
It takes a bit of care to line up the bolt holes during installation, especially the first time.
Fits electric heavy-duty trucks, new energy dump trucks and semi-trailers.
Trailers and dump trucks on mountain roads have chassis and trailer parts that take constant knocks, leading to dents, broken parts or even lost chains.
Our chassis components are built to heavy-duty truck standards.
Steel plates and brackets use solid material, so they rarely break even after years of heavy use.
The surface is treated for rust resistance, so it won't rust through even when stored outdoors.
They're not light, so you'll need some muscle to lift them during installation.
Perfect for semi-trailers and dump trucks used in long-haul freight or construction sites.
For trucks working on construction sites or hauling gravel, engine intake dust is a big problem. A clogged air filter leads to high fuel consumption and weak power.
This air cleaner mounts at the engine intake with a tight-sealed housing, keeping dust out.
The internal filter element offers strong filtration, so it won't clog easily even on dirt or coal roads. You don't need to remove the whole unit to replace the filter - just pop open the clips.
It's quite large, so you'll need to adjust the position a bit for vehicles with tight chassis space.
Fits heavy-duty dump trucks and semi-trailers like Howo and Shacman.
When a truck is fully loaded on mountain roads, the last thing you want is a weak rear axle or broken half-shaft.
This drive axle is installed on the rear of heavy-duty trucks. It has a thick housing and well-matched internal gear set, providing strong starting power and stable operation.
The one-piece cast axle housing resists deformation under heavy loads, and the differential is protected to prevent jamming from stones on rough roads.
It's quite heavy, so you'll need lifting equipment for replacement; it's too heavy to lift by hand.
Fits heavy-duty dump trucks and semi-trailers like Howo, Shacman and Hongyan.
