Lonffery Trailer Equalizer Kit 2-Pack 7-3/4" Triangle Equalizers with Shackle Kit — Fits 3,500–5,200 lb, Ready-to-Install

Lonffery 2-pack 7-3/4" trailer alex equalizers are triangle-style equalizers and a full shackle kit designed to mount double-eye leaf springs on trailers rated about 3,500–5,200 lb.

When rebuilding or maintaining a leaf-spring trailer suspension, having the correct equalizers and matching shackle hardware matters for proper articulation and safe towing. This Lonffery kit bundles two 7-3/4" triangle equalizers with the required shackle straps, bushings and bolts so you get a matched set that’s ready to install. The parts are sized to fit most small-to-medium utility, boat, and cargo trailers that use double-eye springs and 9/16" hardware.

What components come in the Lonffery equalizer kit and in what quantities?

The kit is supplied as a complete axle shackle package so you won’t need to hunt for matching bushings or bolts. It includes two triangle equalizers plus the shackle straps, bushings and fasteners needed to attach the springs and equalizer to the hanger and beam.

• Two 7-3/4" long triangular equalizers
• Eight 3-4/5" long by 1-1/4" wide shackle straps
• Eight EQ-E1 style bushings for the equalizer eyes
• Fourteen 9/16" bolts and nuts for mounting

Will these equalizers fit my trailer and axle weight?

These equalizers are generally specified for trailers with axles in the approximate 3,500–5,200 lb range. Fit depends on your spring eye spacing and hanger geometry; measure your existing equalizer length and shackle strap size to confirm compatibility before purchase.

• Typical fit range: 3,500–5,200 lb axle assemblies
• Equalizer length: 7-3/4" (matching many common double-eye setups)
• Shackle strap size: 3-4/5" long, 1-1/4" wide
• Hardware: 9/16" bolts commonly used on these trailers

How difficult is installation and what tools are required?

Lonffery designed this kit for straightforward installation by a competent DIYer or a trailer shop. Basic mechanical tools and some attention to torque specs are required; replacing shackles and equalizers typically involves supporting the axle and removing old fasteners first.

• Required tools: jack, jack stands, socket/wrench set for 9/16" hardware
• Steps: support axle, remove old hardware, replace shackle straps and bushings, install equalizer and torque bolts
• Installation tip: replace worn bushings and hardware in matched sets for even wear

What materials and qualities should I expect from these components?

The kit combines stamped metal equalizers and shackle straps with molded bushings and standard-grade mounting bolts. It’s designed for durability in trailer service conditions, providing stable spring articulation and replacement parts that align with typical OEM-style configurations.

• Equalizers: triangle-stamped metal sized 7-3/4" for double-eye springs
• Shackle straps: heavy stamped straps, 3-4/5" long, 1-1/4" wide
• Bushings: EQ-E1 style to fit equalizer eyes and shackles
• Fasteners: fourteen 9/16" bolts and nuts included for mounting

Who is this for? The Lonffery 2-pack 7-3/4" equalizer and shackle kit is aimed at trailer owners, repair shops, and fleet maintainers who need a matched replacement set for double-eye leaf spring suspensions on small to medium trailers. If you’re restoring a utility trailer, replacing worn shackles on a boat trailer, or keeping a cargo trailer in service, this kit supplies the core components to restore proper spring balance and articulation. Always confirm measurements and axle capacity before installation, and consult a qualified mechanic if you’re unsure about fit or torque requirements.
