Model: High Capacity Swing Type
Securing heavy oversized spare tires under severe dynamic road vibrations requires rear-chassis mounting hardware engineered for high torsional rigidity and fatigue resistance. The Model: High Capacity Swing Type Heavy-Duty RV Spare Tire Carrier by HENGHONG represents an industry-grade, swing-out tire mounting system designed for seamless integration onto Class A/C motorhomes, luxury travel trailers, fifth-wheels, and rugged overland vehicles. Fabricated from heavy-wall, high-tensile structural carbon steel, this carrier delivers a certified static and dynamic load capacity of 150 lbs (68 kg), effortlessly supporting heavy mud-terrain and oversized steel-rimmed spare assemblies up to 33 inches.
Manufactured in our 39,000 m² ISO9001-certified, Intertek-verified production facility in Zhejiang, China, this tire carrier utilizes a smooth-rotating, heavy-duty hinge pivot assembly paired with a dual-stage positive locking mechanism. Unlike traditional static bumper mounts that block rear access doors and suffer from metal fatigue under vertical road forces, HENGHONG's advanced swing-out design permits full, unobstructed access to rear cargo bays. Backed by a high-durability, multi-stage automotive-grade powder coat, it provides global RV OEMs and aftermarket parts distributors with a highly reliable, zero-play, and corrosion-resistant rear-chassis accessory.
For caravan chassis engineers and global fleet procurement managers, selecting a tire carrier requires balancing rear-axle weight distribution, structural longevity, and user safety during emergency roadside tire changes.
| Technical Performance Metric | Standard Fixed Bumper Brackets | HENGHONG Heavy-Duty Swing-Out System | Fleet & Field Engineering Outcome |
|---|---|---|---|
| Rear Cargo Accessibility | Blocks rear access doors, slide-out trays, or engine bays, requiring complete tire removal for maintenance. | Features a smooth 180-degree manual swing-out radius with a heavy-duty self-locking retention pin. | Provides instant, clear access to rear compartments without removing the heavy spare tire. |
| Vibration-Induced Fatigue | Welded joint connections crack under cyclic off-road vibrations, leading to dangerous bumper sag or loss of cargo. | Integrated anti-rattle tension alignment bolts and heavy-duty gusseted steel backing plates. | Eliminates dynamic play and wobbling, preventing stress fractures on the vehicle's rear frame. |
| Rust & Environmental Wear | Standard single-layer paint chips easily, resulting in rust-frozen lug nuts and seized structural pivot joints. | Undergoes automatic zinc-phosphate pretreatment before a high-density, matte-black powder coat is applied. | Guarantees rust-free operation and easy lug nut turning, even after years of exposure to salt and rain. |
| Mounting Adaptability | Limited to specific bumper sizes, often requiring custom welding or drilling on composite backwalls. | Universal bolt-on frame and bumper flange mounting. Accommodates multiple hub and offset specifications. | Reduces assembly line installation times and fits a wide variety of chassis designs. |
Direct sourcing from HENGHONG's established 22-year manufacturing infrastructure provides global purchasing groups and aftermarket retailers with complete material heat-number traceability, regulatory compliance, and steady profit margins.
