Weld-on trailer axle spring perch set for 2.375" round axle tubes commonly used on 3,500 lb trailer axle applications. Supplied as a matched set of two spring seats.
This R&P Carriages spring perch set is designed for trailer axle work where a weld-on leaf spring seat is needed on a 2.375" round axle tube. These perches help locate and support the leaf springs on compatible trailer suspension setups and are commonly used with 3,500 lb trailer axles.
Spring perch placement matters. Before welding, confirm axle diameter, spring center spacing, axle orientation, and suspension alignment so the trailer tracks correctly after installation.
Compatibility: Fits 2.375" diameter round axle tubes.
Trailer / System Fit: Used for leaf spring trailer axle suspension applications.
Installation Notes: Verify spring center spacing, axle tube diameter, perch location, and axle orientation before welding.
Performance Insight: Proper spring perch placement helps keep the axle square under the trailer and supports correct leaf spring alignment.
Selling Brand: R&P Carriages
