Maximum-drop Equal-i-zer shank for highly lifted tow vehicles. 12" drop and 15" rise. Fits both 2" and 2-1/2" receiver tubes. 12" overall length, 1-1/4" on-center mounting holes. For 6K, 10K, 12K, and 14K no-shank Equal-i-zer systems. High-grade American steel.
The 90-02-4711 is the highest-drop shank in the Equal-i-zer 2" shank lineup — providing a full 12" of drop for tow vehicles where the receiver sits significantly higher than the trailer coupler. This scenario is most common on heavily lifted trucks, high-clearance 4x4 builds, and HD trucks with factory high-ride suspension where standard and even specialty shanks don't reach the correction needed to level the trailer.
At 15" of rise when inverted, the 90-02-4711 also covers setups where the coupler sits substantially above the receiver — uncommon but encountered with certain gooseneck-style conversions or very tall trailer tongues. Unlike most Equal-i-zer shanks which fit only one receiver size, the 90-02-4711 is confirmed to fit both standard 2" and 2-1/2" receiver tubes, making it genuinely universal across most hitch configurations. Adjustability is measured from the inside top of the receiver to the base of the hitch ball per Equal-i-zer's standard measurement convention. Built from high-grade American steel and made in the USA by Progress Mfg.

1. "No-Shank" systems only: The 90-02-4711 is for Equal-i-zer weight distribution hitches sold without a shank. If your system came with a shank, this is a replacement or upgrade for setups that need more drop than the included shank provides. 2. Measure your required drop carefully: Equal-i-zer measures from the inside top of the receiver to the base of the hitch ball — not from the top of the receiver opening. Follow Equal-i-zer's procedure: • Measure from the ground to the inside top of the receiver (loaded, on level ground) • Measure from the ground to the trailer coupler height (trailer loaded, on level ground) • The difference is your required drop 3. Asymmetrical drop/rise: The 90-02-4711 has a 12" drop but a 15" rise when flipped — confirm which orientation your setup requires before ordering. 4. Compatible systems: 6K, 10K, 12K, and 14K Equal-i-zer no-shank models only. Not for use with 4K systems. Use Equal-i-zer's Shank Calculator at equalizerhitch.com or call (800) 478-5578 to confirm this is the correct shank for your specific combination.
Equal-i-zer measures shank adjustment from the inside top of the receiver to the base of the hitch ball. 1. Load your tow vehicle as it will be during towing 2. Measure from the ground to the inside top of the receiver on a level surface 3. Load your trailer as it will be during towing 4. Measure from the ground to the trailer coupler height 5. Calculate the difference: Receiver height minus coupler height = required drop (or rise if coupler is higher) 6.
