Shocker Hitch 20K 2 Inch Air Receiver Hitch Base Frame with 2 D-Handle Pins

Description

Cushion heavy trailer impacts with the Shocker Hitch 20K Air Receiver base frame. Engineered for 2in class 4 receivers, this heavy-duty steel unit isolates jarring fore-and-aft chassis chucking up to 20,000 lbs. It accepts multiple Shocker Hitch ball mounts. You must source ball mount attachments separately because this SKU includes the bare base frame.

Plate steel side uprights enclose an industrial rubber air spring inside a welded structural frame. The solid 2in square steel shank slides into class 4 receivers, held by high-shear hitch pins. The bare frame weighs 52 lbs, with outer dimensions spanning 14in length by 8in width by 12in height. Dual greasable pivot pins support the front channel, carrying 2,000 lbs vertical tongue force while stopping lateral deflection during sharp turns.

• Integrated air spring handles up to 20,000 lbs gross trailer weight.
• Vertical channel accepts diverse ball mounts, drop brackets, and clevis attachments.
• Twin zinc-plated steel D-handle pins enable fast attachment adjustments in the field.
• Side-mounted brass Schrader valve permits pressure tuning between 10 and 100 PSI.
• Cold-rolled steel pivot pins withstand high dynamic shear stress on washboard roads.
• Black powder coat finish prevents corrosion from winter highway deicers and salt.
• Greasable bronze bushings feed lubricant to pivot points for long service life.

Bench Dynamic Damping Verification Data

Dynamic test rams confirm an 80 percent reduction in peak receiver tongue shock during drop-curb drop tests. Vertical test loads of 2,000 lbs compress the internal air spring without bottoming out the internal rubber stops. Frame deflection under 20,000 lbs forward drawbar pull measures less than 0.012in across the solid steel shank. Air chamber burst tests show the rubber bladder withstands 350 PSI before casing deformation. In-cab noise monitors record a 15 dB clatter drop during rough highway travel.

Field Usability Periodic Maintenance Schedule

Pulling the 2 D-handle pins requires 10 lbs hand effort to slide ball attachments up or down the channel. Do not purchase this base frame for 2-1/2in receivers without an approved adapter sleeve.

• Inject NLGI 2 lithium grease into pivot zerks every 30 days.
• Check air spring pressure with an accurate gauge every 14 days.
• Inspect channel pin retention clips for fatigue every 60 days.
