Premium-quality Howo Leaf Spring engineered for extreme durability. Trusted by fleets worldwide — experience zero compromise with certified Sinotruk HOWO components. Your journey to unmatched performance starts here.
The Howo leaf spring is the backbone of your truck’s suspension, absorbing road shocks and maintaining axle alignment under heavy loads. As a trusted Sinotruk Truck partner, we supply OEM‑grade leaf springs for HOWO 371, 420, T7H, and mining dump trucks. Our Howo leaf spring assemblies are made from SUP9/SUP11A steel, heat‑treated to handle extreme loads without permanent deformation. Whether you need a front spring, rear spring, or complete set, our springs provide reliable support and consistent ride height.
With shot‑peened surfaces and anti‑corrosion coating, our leaf springs last up to 500,000 km. Stop sagging, cracking, and axle misalignment – upgrade to genuine Sinotruk suspension components. We stock multi‑leaf packs (10‑14 leaves) for all wheelbases and load ratings.
Multi‑leaf design (10–14 leaves) provides progressive spring rate, supporting up to 16 tons per axle without bottoming out.
Shot‑peened leaves and heat‑treated SUP9A steel resist cracking – tested to 500,000 km under full load.
E‑coated plus powder‑coated finish prevents rust, even in salt‑spray or high‑humidity environments.
Cold‑rolled spring eyes with sintered bronze bushings ensure smooth articulation and reduce wear on shackles.

Howo 371 / 420 (WD615, D12)
Front 10‑leaf and rear 14‑leaf springs fit all 6×4 and 8×4 dump trucks and tractors. Heavy‑duty mining trucks use 16‑leaf rear packs.
Howo T7H / TH7 / Sitrak
Use parabolic springs for improved ride and reduced weight. Also compatible with MC11/MC13 chassis.
“Replaced the rear springs on our Howo 371 dump trucks with the 14‑leaf set. No sagging after 200,000 km. Excellent quality.”
– Diego, Quarry Owner, Peru“The parabolic springs for our T7H made a huge difference in ride comfort. No more harsh bottoming out on rough roads.”
– Ahmed, Fleet Supervisor, UAE“We bought 16‑leaf springs for our mining HC16 axles. They handle 45 tons of ore daily with no visible sag.”
– Suresh, Mine Operator, India“Perfect fit and fast delivery to Russia. The springs came with new center bolts and bushings. Saved us weeks of downtime.”
– Viktor, Fleet Mechanic, RussiaWhy Upgrading Your Howo Leaf Spring is Critical for Safety & Performance – Worn or broken leaf springs directly affect axle alignment, braking stability, and tire wear. A single broken leaf reduces load capacity by up to 30% and can cause the axle to shift during hard braking. Our Howo leaf spring sets are manufactured using premium SUP9A and SUP11A alloy steel, hardened to HRC 42‑48 for optimal flexibility and strength. Each leaf is shot‑peened to relieve residual stress, then coated with anti‑rust epoxy. For extreme mining applications, we offer 16‑leaf packs with a 20% thicker main leaf. We also supply the necessary hardware: U‑bolts, center bolts, spring clips, and polyurethane bushings.
Correct spring selection maintains your truck’s original ride height, ensuring proper driveshaft angle and preventing costly driveline vibrations. For fleets, we recommend replacing both left and right springs at the same time to maintain balanced handling. All our springs come with a 12‑month warranty against breakage. Order directly from our global warehouses and keep your Howo stable under any load. Genuine Howo leaf spring – the foundation of your heavy‑duty suspension.
