Lonffery Trailer Axle Spring Perch Seats 2-3/8" Weld-On 4-Piece Steel Kit for Leaf Springs

Lonffery Trailer Axle Spring Perch Seats are a 4-piece, weld-on steel kit engineered to mount 2-3/8" round axles and firmly support leaf springs for reliable towing performance.

These Lonffery perch seats are made for small utility and light-duty trailers where a precise fit and sturdy connection between axle and spring are essential. Fabricated from high-strength steel and shaped to accept a 2-3/8" curved axle, the set includes four identical perches so you can replace or upgrade one axle's mounting points quickly. The parts are pre-formed with a 0.67" hole for spring saddle bolts, a 4" length and a 1.85" width to match common trailer spring hardware.

How do these perches attach to my trailer axle?

These Lonffery seats are designed for weld-on installation directly to a 2-3/8" round axle tube. Proper welding produces a permanent, rigid joint that keeps leaf springs aligned and prevents shifting under load.

• Weld-on design — no U-bolts required for the primary anchor
• Curved base sized for 2-3/8" axle diameters for tight contact
• 0.67" bolt hole accommodates standard spring bolts or saddle hardware
• Recommended welding by a qualified technician for safety and durability

What are the exact dimensions and material details?

Each Lonffery spring perch is precision-formed to standard trailer dimensions so they match most light trailer spring setups. The kit is constructed from heavy-duty steel to withstand road stress and resist deformation when installed correctly.

• Overall length: 4.00" — fits common spring placements
• Width: 1.85" — compatible with most leaf spring pads
• Hole diameter: 0.67" — for spring saddle or center bolt use
• Curved base diameter: sized for 2-3/8" round axles; high-strength steel construction

Will this kit work for my trailer type and load needs?

These perches are intended for light-duty and small utility trailers, not heavy commercial haulers. They give a robust, permanent mounting point for trailer leaf springs on typical recreational or work trailers.

• Best for small utility, boat, and light cargo trailers
• Suitable when upgrading or replacing worn spring seats on one axle
• Not intended for oversized loads or heavy commercial tandem axles without verification
• Use correct welding technique and torque spring hardware to manufacturer specs

Who is this for? Installers, DIY trailer owners, and small fleet managers who need a dependable, weld-on solution for connecting leaf springs to a 2-3/8" round axle will find this Lonffery 4-piece kit useful. If you want a precise fit, heavy-steel construction, and the ability to replace or upgrade a single axle's spring seats, this set provides the key dimensions and hole spacing common to standard trailer suspensions. Always verify axle diameter and spring hardware compatibility before purchasing, and have welding performed by an experienced technician for safe towing performance.
