UCF Axle & Spring Parts

UCF Axle & Spring Parts for Trailers and Trucks

When a trailer's suspension starts to sag, squeak, or wear unevenly, the root cause is almost always found in the axle and spring assembly. UCF (The Universal Group) has built a well-regarded reputation in the trailer suspension replacement market by supplying the precise components that keep leaf spring systems working as designed. Their Axle & Spring Parts lineup is a focused, purpose-built collection aimed squarely at keeping light, medium, and heavy duty trailers rolling safely and smoothly.

What UCF Offers in This Category

UCF specializes in trailer axle leaf springs, related hardware, and the small-but-critical connecting components that hold it all together. Their product range in the axle and spring category includes two distinct leaf spring styles:

• Double Eye Leaf Springs – Available in multiple lengths and capacities, these springs feature eyes at both ends for secure, fixed mounting to a trailer's spring hanger system. Many variants come with bushings included for a complete, ready-to-install solution.
• Slipper Style Leaf Springs – Designed with one fixed eye and one flat or radius-ended tail that "slips" through a bracket, these springs allow for flex under load while maintaining a lower profile. UCF offers both flat-end and radius-end configurations in this style.

Complementing these springs are UCF's nylon leaf spring bushings — small components that insert into the eye of a leaf spring to ensure proper sizing and alignment with the suspension bolt. Parts like the PE-225 and PE-226 are precision-sized nylon bushings engineered specifically for trailer axle applications, preventing metal-on-metal contact and reducing wear over time.

Why UCF for Axle & Spring Parts?

UCF's product lines are designed for the trailer replacement market, meaning their springs are made to match the dimensional and load-bearing specifications of common trailer axle systems — not adapted from automotive applications. Leaf springs in the UCF lineup cover a range of per-spring capacities and leaf counts to suit different trailer weight ratings, from lighter utility trailers up to heavier hauling rigs. Paying attention to unloaded length, center-eye-to-bolt dimensions, and per-spring capacity ratings is essential when selecting the right replacement, and UCF's well-documented part specifications make that matching process straightforward.

For anyone maintaining or restoring a trailer suspension system, UCF's axle and spring components represent a practical, purpose-matched solution — whether you're replacing a single worn bushing or refreshing an entire spring assembly.
