99000520021 SHACMAN Rear Steel Plate Support

99000520021 is a rear steel plate support for SHACMAN X3000/X5000/M3000S trucks, a core rear suspension load-bearing part. It fixes the leaf spring, transmits load to the axle, and absorbs road vibration. We've sold it to 30+ repair shops and fleets for 5 years-users say it's steady: no deformation, no cracking, no loosening, no abnormal wear.

It has integrated welding structure: Q355B steel plate main body (16mm), Q460 alloy steel reinforcing rib (12mm). Surface is shot blasted + electrophoretic anti-corrosion, contact surface has wear-resistant paint. Heavy-load (≤12000kg), -40℃ to 120℃, vibration, corrosion-none mess it up. Optimized design extends suspension life by 25%. Fits SHACMAN's original mounting positions perfect: align holes and fasten, no mods needed. We test load-bearing, welding strength, and anti-corrosion performance, so it's reliable.

① High load-bearing: ≤12000kg maximum load, firm structure, no cracking under heavy load.

② Wear-resistant & anti-corrosion: Electrophoretic treatment + wear-resistant paint, long service life.

③ Vibration absorption: Absorbs road impact, improves driving comfort.

④ Fits SHACMAN fast: Matches original dimensions and holes, easy to install, saves time.

Only SHACMAN X3000/X5000/M3000S (rear suspension). No old SHACMAN F3000, HOWO, FAW J6-different specs cause safety risks.
