Product Details

The UCF 178 (UNA-178) is a slipper-style trailer axle leaf spring designed for reliable suspension performance on utility trailers, boat trailers, and cargo trailers. This radius end leaf spring measures 25" long by 1-3/4" wide, featuring a 3-leaf construction built to handle demanding loads.

Key Specifications:

  • Capacity per spring: 750 lbs (700 lb rating also referenced)
  • Number of leaves: 3
  • Unloaded length: 25" (24.5" nominal)
  • Width: 1-3/4"
  • Center eye to spring bolt: 12"
  • Spring bolt to spring end: 14.5"
  • Radius end design with eye (bushing sold separately)
  • Camber: 4.00" in free position

Slipper radius end trailer leaf springs are painted black for corrosion resistance. This spring is designed to mount with standard U-bolts and tie plates, providing a direct replacement for worn or damaged trailer suspension components. The radius end configuration allows for smooth articulation during travel, while the 3-leaf design balances load capacity with ride quality.

Note: Eye bushing sold separately (UCF PE-227 or equivalent). Measurements shown reflect the spring in its free, unloaded position. Always verify spring dimensions and capacity match your trailer's requirements before installation.

Just placed the order , ask again after order has arrived here in AZ

Dont kno just ordered

Thanks

Product received as described. Fast shipping! I will definitely purchase from Autoplicity again.

I saved almost %50 using autoplicity. I did not think that I would be able to afford the Odessy battery for my gold wing as they were priced around $175.00 I found one with Autoplicity for less than $100 they shipped it 2 days after if placed the order!

so far all good.

Fine

I'm very pleased with my order from Autoplicity. The item I ordered was the cheapest in price compared to other in-store and online merchants. I was provided a tracking number and my shipment arrived on time. I would use Autoplicty again and recommend them to others.

Extremely easy to find the parts and place the order

Great experience so far, stumbled upon this website searching the internet for Bilstein Shocks...

Great pricing on almost every product! Quick process and fast shipping! Will definitely order from Autoplicity again in the future.
