This listing is for an EQ-R2 straight leaf spring equalizer bar (part number: EQ-R2), designed to fit UFP systems. With an 8" overall length and 5-1/2" Dimension A, this straight equalizer is specifically used on multi-axle trailers and is compatible with Double Eye style Leaf Springs. It is commonly applied to multi-axle boat trailers, serving as a key component to maintain stable suspension performance. Featuring a 1-3/4" spring width, 1-7/16" Dimension B, and 9/16" Dimensions C & D, it comes equipped with 9/16" ID x 0.685" OD Nylon bushings for smooth operation. Crafted as a brand-new, unused, unopened and undamaged item, it is built to meet standard trailer suspension requirements, serving as a reliable replacement for worn or damaged equalizer bars. The straight design ensures stable alignment with leaf springs, effectively distributing weight evenly across the trailer axle, reducing stress on suspension parts and ensuring a smoother ride during towing.
