Product Description: Slipper Leaf Spring 4321-5
The 4321-5 slipper leaf spring is a versatile suspension component suitable for various trailer types, including utility, boat, travel, dump, and horse trailers.

Measurement Guidelines
To ensure an accurate fit, measure along the surface of the leaf spring. Note that eye-to-end measurements may vary over time due to the spring flattening with use. If you have any questions, contact the experts at Spring Works for assistance or open our chat for AI responses to common questions.

Important Replacement Note
Always replace UNA-207 slipper leaf springs in pairs to maintain proper height, axle alignment, and performance.

The only socks that I can wear with my hey dudes. They stay on my ankles and never slid down into the shoe. I will forever order these as long as they are available. They are comfy too!

Good option, especially in warmer weather
Size: 6-10, Color: Black
High quality socks and very durable. Nice touch adding the grip on the back of the ankle so the sock stays up. Size is a true fit to the size of your foot as well.

Love these socks!
Size: 6-10, Color: White
Comfortable, no show, and most importantly The Do No Slip!!!! I keep coming back to add to my supply because they have become the only sock I wear. I’ve been using them for a couple years now and they hold to great to washing, bleaching and the dryer. Highly recommended.
