The SZ970000782 Shacman Front Spring Rear Bracket is a key load-bearing and connecting part for Shacman heavy-duty trucks' suspension systems (tractor, cargo, dump trucks). Installed at the rear end of the front leaf spring, it fixes the spring, transmits vehicle load, and absorbs road impact. It connects the front axle, leaf spring, and frame into one-evenly transferring vehicle weight and road reaction force to the frame, while working with the leaf spring to buffer vibration and reduce uneven road impact on the body. This is super important for ensuring suspension stability, improving driving comfort, and protecting the frame/front axle from excessive stress damage.
Every user says it works reliably: strong load-bearing capacity (max ≥80kN), excellent rigidity, no deformation/cracking/fatigue failure even under long-term heavy-load operation (80% full load) and frequent road impact. This avoids suspension system failure from component issues. We use good materials and precision forging + heat treatment to make it: the main body is high-strength 40Cr alloy steel-wear-resistant and impact-resistant. Connecting holes have reinforced bushings-wear-resistant and corrosion-resistant. Welding joints are robot-welded fully-high strength and stable performance. The installation interface, bolt spacing, and fit dimension fit the original Shacman suspension system (X3000/X5000/F3000 models) exactly, so it installs with no mods. It handles tough conditions--40℃~100℃ extreme temps, 2-500Hz road vibration, and rainwater/salt spray corrosion-without main body rusting, bushing wear, or welding joint cracking. Swapping it is easy: no need to disassemble the entire suspension, just jack up the frame, remove old bracket and leaf spring bolts, install new bracket, reconnect leaf spring, tighten bolts to specified torque, and lower the jack to test suspension flexibility. Before shipping, we test 'em strict: load-bearing (withstand 80kN no deformation), fatigue durability (2 million vibration cycles no failure), and corrosion resistance-so it's reliable.

advantages
① Superior load-bearing capacity: 40Cr alloy steel main body + robot welding ensure stable load transmission, meeting Shacman's heavy-load demand (max ≥80kN) and maintaining structure under extreme conditions.
② Excellent impact resistance & rigidity: Precision forging + heat treatment enhance toughness and rigidity, absorbing road impact and reducing vibration to the frame-improving driving stability by 30% vs ordinary stamping brackets.
③ Perfect for Shacman: Made to Shacman's original suspension design-installation interface, bolt spacing, fit dimension match. No drilling or welding needed-saves 40% maintenance time vs universal front spring rear brackets.
④ Durable & reliable: Anti-rust treated 40Cr steel resists corrosion/wear, reinforced bushing extends connecting part life-maintains stable performance in harsh environments for 600k+ km.
Application Scope
This SZ970000782 Shacman Front Spring Rear Bracket is only for Shacman heavy-duty trucks-X3000, X5000, F3000 models with original Shacman suspension systems. It won't work on Shacman with modified suspension structures or other brands (FAW Jiefang, Dongfeng Tianlong). Those have different frame dimensions, leaf spring specs, or installation interfaces-this front spring rear bracket won't fit or work.
FAQ
Q: Suspension abnormal noise/vehicle leans after install?
A: First check installation (alignment with leaf spring/frame, bolts tightened to specified torque). If good, inspect leaf spring (replace if deformed/broken). If normal, check connecting hole bushing (replace if worn). Still faulty? Replace the bracket (rare defect).
Q: How to maintain the SZ970000782 Shacman front spring rear bracket?
A: 1. Check bracket, welding joints, bushing for wear/corrosion/cracking every 30k km (replace if abnormal); 2. Clean surface often to remove dust/mud/salt (avoid corrosive cleaners); 3. Inspect bolts for looseness during maintenance (tighten to specified torque).
Q: Need to replace front spring front bracket with rear one?
A: Not mandatory but recommended. If the front bracket is old (over 400k km) or worn (deformation/cracking), replacing both ensures balanced leaf spring load-bearing, avoiding uneven stress and affecting suspension stability.
