Lonffery Trailer Axle Spring Perch Seats for 2-3/8" Axles — 4-Piece Weld-On Steel Kit, Heavy-Duty

Lonffery Trailer Axle Spring Perch Seats are a four-piece, weld-on kit sized for 2-3/8" round axles that securely locate leaf springs for light-duty trailers and utility trailers.

These precision-made perch seats are built from heavy-duty steel and engineered to fit 2-3/8" trailer axles, offering a straightforward replacement or upgrade option when restoring or customizing small trailers. The set contains four identical perches — enough for one axle — with clearly stated dimensions so you can confirm fit before welding. They’re intended for weld-on installation to create a permanent, rigid anchor point for leaf springs and to improve alignment and towing stability.

How do these perch seats fit a 2-3/8" trailer axle?

Each perch is formed with a curved base sized to match a 2-3/8" round axle for a tight, consistent contact area that simplifies welding and prevents misalignment. The hole and plate dimensions are designed for standard U-bolt or spring mounting patterns used on light-duty trailers.

• Curved base diameter: 2-3/8" to match axle tube circumference
• Overall length: 4" for stable spring support
• Width: 1.85" for proper seat contact
• Hole diameter: 0.67" for common fasteners

What materials and construction should I expect?

Lonffery perches are constructed from high-strength steel to resist deformation under load and provide a long-lasting mounting surface for leaf springs. The robust plate thickness and welded design give a durable, permanent connection when properly installed by a qualified welder.

• Material: heavy-duty steel for improved load handling
• Finish: raw steel ready for primer/paint or corrosion protection
• Design: welded-on style for a secure, non-slip fit
• Set quantity: 4 pieces—sufficient for one axle replacement

How easy is installation and what tools are required?

These are weld-on perches intended for a permanent installation and require basic metalworking tools plus welding experience or a professional installer. Preparation and correct positioning are key: clean the axle surface, clamp the perch in place, tack-weld to check alignment, then complete the welds and finish to protect against corrosion.

• Installation: weld-on—professional welding recommended
• Tools needed: grinder, clamps, welding equipment, measuring tools
• Prep steps: clean axle tube, fit and clamp, tack, then continuous weld
• Post-install: paint or undercoating to prevent rust

Will these perches work with my trailer springs and hardware?

The perches are intended for standard light-duty leaf spring configurations and common fasteners; confirm that your spring eye spacing and U-bolt dimensions align with the perch plate size and hole diameter. Because the kit is sized and shaped for common utility trailer setups, many users will find it compatible, but checking measurements before purchase avoids fitment issues.

• Compatible with light-duty leaf springs and common U-bolt patterns
• Hole diameter: 0.67"—verify with your hardware sizes
• Plate width and length accommodate typical spring seats
• Sold as a 4-piece kit—sufficient for one axle upgrade
