UCF Leaf Spring
UCF Leaf Springs: Built from the Ground Up for Trailer Suspension
When it comes to trailer axle suspension, few names carry the credibility that UCF (The Universal Group LLC) has earned through decades of focused engineering. Leaf springs are where UCF's story begins — the company's roots trace directly to the leaf spring business, and that foundational expertise shows in every product they produce for the replacement market.
Leaf springs are the backbone of trailer suspension, absorbing road shock, supporting load weight, and keeping axles properly positioned under the full range of operating conditions. Choosing the right spring — matched precisely to your trailer's axle capacity and mounting configuration — is critical to both safety and longevity. UCF's catalog addresses this need with a broad range of specifications tailored specifically to the light, medium, and heavy duty truck and trailer replacement market.
Double Eye & Slipper Style Spring Designs
UCF's leaf spring lineup covers the two most common trailer suspension configurations. Their Double Eye springs feature forged eyes at both ends, accepting standard nylon bushings for a secure, low-friction mount to hangers and shackles. These are available in a wide range of leaf counts — from compact 3-leaf units to heavy-duty 7-leaf assemblies — and load ratings spanning from 700 lbs to 3,000 lbs per spring. Their Slipper Style springs feature a radius end on the trailing side, accommodating the flex travel common in tandem and multi-axle setups.
UCF's springs are constructed from high-quality durable steel, and most models come complete with nylon bushings pre-installed in the eyes, simplifying installation and reducing the need for additional hardware sourcing. Spring widths are standardized at 1-3/4", making UCF units a direct fit for the vast majority of popular trailer axle hangers on the market today.
A Range Built for the Replacement Market
What sets UCF apart in the leaf spring category is the breadth of their UNA-series product lineup. Whether you're rebuilding a utility trailer running a single 1,000 lb axle or restoring a multi-axle flatbed demanding 2,000 lbs or more per spring, UCF has a matched part number. Length options span from compact 20" units up to nearly 30", covering the full spectrum of common trailer frame configurations.
UCF's engineering and quality control teams work continuously on product development and process improvements, ensuring that replacement springs meet or exceed OEM specifications for fit and load performance. For anyone working in the trailer service, marine, or recreational towing space, UCF leaf springs represent a reliable, purpose-built solution from a manufacturer whose heritage in this exact product category is unmatched.
