Features to know about

Smooth Ride Over Rough Roads: 3-Leaf Spring Flexes to Absorb Shock

Bumpy and uneven surfaces can make a trailer jump and rattle. This 3-Leaf Double-Eye Spring flexes to absorb that shock, keeping the trailer steady and the ride smoother. Each spring is rated for 1,650 lbs, giving a total axle capacity of 3,300 lbs. The multi-leaf design spreads the load evenly, reducing wear and tear on the frame and suspension parts while keeping the ride level and controlled.

Compact and Strong Fit: 18-5/16" Eye-to-Eye Length with 1-3/4" Width

When space is tight and precision matters, the 18-5/16" eye-to-eye length makes this one of the shortest double-eye springs available. It’s built 1-3/4" wide to fit standard hanger and shackle setups, giving a snug, reliable fit that keeps alignment true. The spring measures 9-1/8" from the front eye to the center, 10-1/8" from the center to the rear, and 3" from the top leaf to the bottom, ensuring consistent geometry and balance.

Long-Lasting Components: Sturdy Steel with 9/16" Nylon-Bushed Eyes

Durability starts with tough materials. This spring is built from sturdy steel for dependable strength and long service life. Each eye is fitted with nylon bushings that have a 9/16" inner diameter, reducing friction and noise while helping the spring pivot smoothly under load. The bushings also protect against metal-on-metal wear so the connection points stay tight over time.

Maintains Proper Geometry Under Load: Extends to 20-1/4" When Flat

Over time, old springs can sag and throw off suspension geometry. This 3-Leaf Double-Eye Spring keeps things in line with consistent flex that maintains proper ride height. It measures 18-5/16" unloaded and extends to about 20-1/4" when fully flattened, which helps ensure the suspension stays balanced across both sides. For best performance, springs should always be replaced in pairs to keep the trailer tracking straight and level.

Good quality and fast shipping!



by:

These worked perfectly on our homemade trailer! I would definitely recommend these.



by:

Ordered 4 of these. One snapped on instillation in a v pattern. Called etrailer and they sent me a new. Great company to deal with!



by:

These are excellent upgrades for a 2000lb axle with only welding on new hangers. These saved me from needing to buy a new trailer because mine was overloaded



by:

They could not have possibly shipped the item any faster.

I scoured the internet in search for an odd sized spring, they had it in stock and it arrived exactly as described waay before it should have arrived considering I cheaped out on the shipping.

I couldnt be any happier with my order.

Too bad all businesses cant get it as right.

Sorry, I did not take any pictures to upload for my review

  • Recommended 20-1/2" Long 4-Leaf Leaf Spring for a 2,800 lbs Axle
    Hey Raymond. The closest 4-leaf leaf spring we have to your measurements is the Dexter item # DX73CR. It measures 20-1/2" long from eye-to-eye and has a 1,400 lbs capacity. This leaf spring is sold individually but it is highly recommend to replace all of your leaf springs at the same time. How did you measure the eye-to-eye distance on your leaf springs? If the weight of your trailer was still on them you most likely need a shorter leaf spring like the 18-5/16" Long item # SP-072275....

    Thank you for providing that information. In addition to the length you will also want to know the capacity of your axle so you can choose the correct leaf spring replacement.

  • Which Double-Eye Leaf Springs Are Suitable For 5,500lb Tandem Trailer?
    The 3-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 23-1/2" # SP-113275 is rated for 1,000lbs each, and since there are two springs per axle the weight capacity would be 2,000lbs per axle. This would not be sufficient for your 5,500lb trailer so you would want a heavier duty leaf spring. I see you ordered 4 of these leaf springs which tells me you likely have a tandem 2 axle trailer. This means each leaf spring must be rated for a minimum of 1,375lbs to be sufficient for a 5,500lb...
