Shocker Hitch 14K 2.5in Air Receiver Hitch & Silver Combo Ball Mount with 2in & 2-5/16in Hitch Balls

Description

Buffer punishing bridge transitions with the Shocker Hitch 14K Air Receiver combo hitch. Engineered for 2-1/2in class 5 receivers, it cushions trailer bounce up to 14,000 lbs gross pull capacity. Reversible silver combo balls handle 2in and 2-5/16in trailer couplers. Hitch extension reduces vehicle departure angle on steep terrain.

Plate steel side uprights carry high-tensile shear pins and durable industrial powder coat. The structural core houses a heavy-duty rubber air bladder with internal bump stops. The chassis weighs 58 lbs unboxed, with outer dimensions spanning 14in length, 8in width, and 12in height. Welded steel gussets stiffen the main 2-1/2in square shank against side deflection under heavy crosswinds. Internal bronze pivot bushings isolate frame-to-ball vibration during heavy equipment transport.

Dynamic Bench Shock Isolation Metrics

Shop test bench evaluations show an 80 percent reduction in peak dynamic shock transfer through the hitch receiver. The air spring maintains damping integrity under continuous 1,400 lbs vertical tongue load. Air chamber pressure increases from 45 PSI to 72 PSI during severe 2-inch drop impacts without bottoming out the internal bumper. Dynamic chucking forces decrease from 3,200 lbs to 640 lbs along the horizontal tow axis. Decibel testing indicates a 14 dB drop in receiver clatter inside the truck cab during concrete washboard road cycles.

Field Usability Maintenance Guidelines

Operators adjust air pressure with a standard tire chuck while viewing the alignment bump stop. Do not purchase this hitch for 2in receiver tubes or light passenger utility vehicles with class 3 ratings.

• Pump NLGI 2 grease into both pivot zerks every 30 days.
• Inspect the rubber air spring for outer wear every 90 days.
• Torque channel mount retention bolts to 100 ft-lbs every 6 months.
