The Equal-i-zer 90-02-4225 is a heavy-duty solid steel adjustable shank designed for 2-1/2" receiver tubes. Whether you need a 4" drop to level a tall trailer or an 8" rise for a lifted tow vehicle, this single shank handles both configurations. Rated at 14,000 lb gross trailer weight and 1,400 lb tongue weight, it pairs directly with Equal-i-zer sway control hitch heads and is compatible with most other adjustable hitch head brands that use 1-1/4" on-center bolt spacing.
Many Equal-i-zer weight distribution and sway control hitch models are sold head-only, without an integrated shank. The 90-02-4225 fills that gap, giving you a purpose-built shank machined from solid high-grade U.S. steel. Six mounting holes spaced at 1-1/4" on-center increments let you fine-tune the hitch head position to match your specific tow vehicle and trailer combination.
The 12" shank length provides enough clearance for most heavy-duty bumpers and receiver extensions. Flip the shank to switch between the 4" drop and 8" rise positions -- no additional hardware needed. Nearly any tow vehicle or trailer pairing that uses a standard 2-1/2" receiver tube will work with this shank.
Use in the 4" drop position for most trailer tongue heights, or flip to 8" rise for lifted trucks and tall receiver applications.
Rated for up to 14,000 lb gross trailer weight and 1,400 lb tongue weight -- suitable for large travel trailers and fifth-wheel adapters.
Six mounting holes centered at 1-1/4" increments provide fitment flexibility across Equal-i-zer heads and most other adjustable hitch head brands.
Machined from solid high-grade U.S. steel for long-term durability under the repeated stress and vibration of weight-distributing towing.
This shank is designed for use with Equal-i-zer sway control hitch heads that do not include a shank. Confirmed compatible models include:
The 1-1/4" on-center bolt spacing also allows use with many other brands of adjustable hitch heads that share the same bolt pattern standard.
Proper trailer leveling is critical for safe weight distribution and sway control performance. As a general rule:
The adjustability measurement for this shank is calculated from the inside top of the receiver tube to the base of the hitch ball position.
