Lonffery Trailer Equalizer Kit 7-3/4" — 2-Pack Triangle Equalizers with Shackles & Hardware for 3,500–5,200 lb Axles

Lonffery 2-pack 7-3/4" trailer equalizers are triangular suspension equalizers and shackle kits designed to restore balanced movement between double-eye leaf springs on trailers rated roughly 3,500–5,200 lb.

These two triangle equalizers with matching shackles, bushings, bolts and nuts provide a complete axle shackle kit so you can replace worn suspension parts without sourcing components separately. Built to fit common small-to-medium trailer axles, the kit includes everything needed to remount double-eye leaf springs and rebuild the equalizer linkage for smoother articulation and improved load sharing.

How does this equalizer kit improve trailer suspension performance?

Replacing a damaged or worn equalizer restores the pivot point between your leaf springs, helping the axle track evenly over bumps and distributing load more consistently across spring leaves. This can reduce binding and uneven wear on springs and other suspension parts.

• Two 7-3/4" triangular equalizers for correct pivot geometry
• EQ-E1 bushings to reduce metal-on-metal contact and wear
• Shackle straps sized 3-4/5" long, 1-1/4" wide for secure spring connection
• Complete hardware set (14 x 9/16" bolts and nuts) for direct swap-out

Will this kit fit my trailer axle and leaf spring assembly?

The Lonffery kit is engineered for common double-eye leaf spring setups and typically suits trailers with axles rated between about 3,500 and 5,200 pounds. Measure your current equalizer and shackle strap lengths to confirm compatibility before ordering.

• Equalizer length: 7-3/4" (triangular style)
• Shackle strap size: 3-4/5" long and 1-1/4" wide
• Intended for double-eye leaf spring systems on small/medium trailers
• Includes bushings and bolts for a like-for-like replacement

What comes in the package and what tools will I need?

The box contains two triangle equalizers, eight shackle straps, eight EQ-E1 bushings and fourteen 9/16" bolts and nuts — enough hardware to service both sides of a tandem or single-axle setup depending on your configuration. Basic hand tools and a torque wrench are recommended for safe, secure installation.

• Included: (2) equalizers, (8) shackle straps, (8) bushings, (14) 9/16 bolts & nuts
• Tools suggested: jack stands, wrenches/sockets for 9/16", torque wrench
• Optional: penetrating oil for rusted fasteners and anti-seize on threads
• Installation time: typically one axle side per hour for experienced DIYers

How durable is the Lonffery equalizer kit for regular trailer use?

The kit uses robust steel components sized for light-to-medium trailer loads and includes bushings to limit wear where parts pivot. Proper installation, correct torque on fasteners and routine inspection will maximize service life.

• Steel equalizers sized for common trailer duty cycles
• Bushings reduce direct metal friction and extend component life
• Supplied nuts and bolts match the equalizer and shackle dimensions
• Routine checks recommended after initial road miles and seasonally

Who is this for: The Lonffery 2-pack 7-3/4" trailer equalizer kit is aimed at trailer owners, DIY mechanics and fleet maintainers who need a complete replacement set for double-eye leaf spring suspensions on small to medium trailers. If you handle routine trailer maintenance or are restoring a trailer’s suspension to prevent binding, this all-in-one kit supplies matching equalizers, shackles, bushings and hardware to get the linkage back to proper working order.
