Features to know about

Even Weight for a Smoother Tow: 18-3/8" Equalizer Transfers Load Between Axles

When weight shifts or rough roads hit, this Dexter equalizer keeps your trailer level and steady. Its 18-3/8" long body connects 2-1/2" wide slipper springs so impact is shared between axles instead of being felt in one spot. That means the load stays balanced and the trailer rides smoother, even with 10,000-lb general-duty axles under it.

Built for Real-World Strength: 1" Center Hole Handles Heavy Loads

The 1" diameter center bolt hole gives this equalizer a solid pivot point that’s ready for tough duty. It mounts securely on the center hanger (sold separately) and stands up to constant movement and road shock. That dependable strength is what keeps the suspension geometry working right and the trailer tracking straight mile after mile.

Reliable Spring Connection: 3/4" Side Hole Fits Rubber-Bushed Eyes

For the spring end, this equalizer uses a 3/4" diameter side bolt hole sized for rubber-bushed eyes on 2-1/2" wide slipper springs. It’s a snug, proper fit that keeps the spring secure without binding. The design also makes replacement straightforward when you’re upgrading worn-out OEM parts or matching an existing setup.

Left or Right Placement Made Easy: Works on Either Side

No need to worry about matching sides—this part works as a left-hand or right-hand equalizer. That flexibility simplifies ordering and installation, especially when replacing both sides on a tandem- or triple-axle suspension. It’s a direct way to restore balance and keep your trailer’s suspension working the way Dexter engineered it.

Video Transcript for Complete Breakdown of the Equalizer for 2-1/2" Wide Slipper Springs

Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this 18 3/8 inches long equalizer for the 2 1/2 inch wide slipper springs, and this is a left hand or right hand configuration. Now, this equalizer will connect your slipper springs on a tandem or triple axle trailer, and transfer impact between the axles to ensure that the load is evenly distributed. Now, when this is installed, the equalizer will suspend from the center hanger right here through this hole. Now, the center hanger is sold separately.

You attach one spring with a bolt through the eye on this end, and then you slip the arched end of the other slipper spring into the equalizer on this end. Again, this will transfer the load and sudden impacts from one axle to another. Distributes the weight evenly, results in a nice, smooth ride for the trailer. Now, this equalizer here is designed for use on trailers with a 10,000 pound general duty Dexter Axle and leaf springs with the 3/4 inch rubber eye bushings. This will allow for a 42 1/4 inch axle spacing.

Few specs on this, we're gonna give you the measurements. The overall length from one end to the other, put our tape measure on that is gonna be 18 3/8 inches long. The width on this, outside to outside is gonna be right at three inches. And the overall height, bottom to the very top is 5 1/4 inches tall. Now again, this is designed to fit 2 1/2 inch wide slipper leaf springs.

The center bolt hole diameter right here is a one inch diameter. And the side bolt hole diameter for mounting the spring is a 3/4 inch diameter. And we did mention the configuration on this can be used for left hand or right hand side. But that should do it for the review on this 18 3/8 inch long equalizers for the 2 1/2 inch wide slipper springs..
