The Equal-i-zer 90-02-5378 is the pocketed outside plate used in the Equal-i-zer sway bracket assembly. It mounts to the outside of the trailer frame and serves as the anchor point where the L-bracket bolts on. Built from 5/8" thick steel and redesigned for faster single-wrench installation, this is the correct OEM replacement plate for trailers with 8" tall frame rails.
When your Equal-i-zer sway bracket outside plate is worn, damaged, or missing, this direct OEM replacement restores full sway control function to your weight distribution system. The pocketed design secures the plate to the outside face of your trailer's frame rail while the integrated pocket accepts the L-bracket that completes the sway bracket assembly.
Equal-i-zer redesigned this plate with thicker 5/8" steel material compared to earlier versions, adding durability at a critical stress point. The updated geometry also allows the full bracket assembly to be tightened down with a single wrench -- no need for a second wrench to hold the opposite side, which speeds up installation considerably.
Installs on the exterior face of the trailer frame rail, correctly positioning the L-bracket for engagement with the Equal-i-zer head assembly.
Heavier-gauge material than earlier plate designs for increased durability at this high-stress connection point in the sway bracket system.
Redesigned pocket geometry allows full installation and tightening with one wrench, reducing setup time compared to earlier two-wrench designs.
Sized specifically for trailers with 8" tall frame rails. Using the correct plate size ensures proper bracket geometry and sway control performance.
The Equal-i-zer weight distribution hitch controls sway through a friction sway bracket mounted to the trailer tongue frame. That bracket uses two plates -- an inside plate and an outside plate -- that clamp to opposite faces of the trailer frame rail. This listing is for the outside plate only (the plate that faces away from the trailer centerline). The L-bracket that links the sway chain to the hitch head bolts directly to this outside plate.
Selecting the correct plate for your frame height is essential. Using an 8" plate on a shorter frame leaves the L-bracket misaligned; using a shorter plate on an 8" frame will not allow the assembly to clamp properly. Measure your trailer's frame height before ordering if you are unsure which size you need.
Equal-i-zer offers pocketed outside plates in multiple sizes to match different trailer frame heights. The 90-02-5378 is sized for 8" trailer frames. If your trailer has a different frame height (for example 6" or 10" rail), you will need the corresponding plate part number for that size. When in doubt, measure the vertical height of your trailer tongue frame rail.
This part is covered by Equal-i-zer's 90-day limited warranty against defects in materials and workmanship when used as intended in the Equal-i-zer sway bracket system.
