Lonffery Trailer Leaf Spring Hanger Kit for 1-3/4" Double-Eye Springs — Front & Rear Hangers, Shackles, Hardware

Lonffery Trailer Leaf Spring Hanger Kit secures 1-3/4" double-eye springs to single-axle frames for reliable towing and suspension support.

Replace worn or corroded suspension hangers with a full hardware kit engineered for single-axle trailers rated roughly 2,000–7,000 lbs. This Lonffery kit bundles front and rear hangers, shackle straps, bolts, and lock nuts sized specifically for 1-3/4" (double-eye) springs to restore correct alignment, stabilize the axle, and simplify reassembly.

How will this kit fit my trailer's springs and axle?

The components are dimensioned to match common 1-3/4" double-eye leaf springs used on 3,500 lb class setups and other trailers in the 2,000–7,000 lb range. Front and rear hangers are sized for correct spring centering and shackle travel, so the axle geometry stays true under load.

• Fits 1-3/4" double-eye leaf springs (common single-axle trailers)
• Includes 3" front hanger and 2-1/5" rear hanger for accurate placement
• Shackle straps measure 4-1/2" to allow proper movement and articulation
• Hardware includes 3" × 9/16" shackle bolts and 9/16" lock nuts for secure fastening

What hardware is included and do I need extra parts?

This kit is a near-complete replacement set for two leaf springs on a single axle: two front hangers, two rear hangers, four shackle straps, six bolts, and six lock nuts. For most repairs you will not need additional parts, though you may want fresh grease or anti-seize on bolt threads and any extra mounting hardware if your frame requires unusual spacing.

• Complete set: 2 front hangers, 2 rear hangers, 4 shackle straps
• Includes 6 shackle bolts and 6 lock nuts sized 9/16" for secure installation
• No extra brackets required for standard single-axle trailers
• Optional: grease, anti-seize, or paint for corrosion protection

How durable and safe is the Lonffery hanger kit?

Each piece is made from heavy-duty steel engineered to withstand towing loads and repeated suspension movement. While not a corrosion-proof finish replacement, the robust steel construction provides long service life under normal trailering conditions; apply paint or coating for extended weather resistance.

• High-strength steel construction for reliable axle support
• Sized and formed to reduce wear on spring eyes and shackles
• Designed to hold typical trailer loads between 2,000 and 7,000 lbs
• Recommend surface treatment to resist rust in marine or harsh climates

Is installation difficult and what tools are needed?

Installation is straightforward for anyone comfortable with basic trailer work: mounting two springs to the frame using the included hangers and hardware. Expect to use a jack or stands to support the axle, wrenches or sockets for 9/16" hardware, and a torque wrench to ensure proper tightness for safety.

• Tools: floor jack, jack stands, socket/wrench set, torque wrench
• Supports adjustable placement to align spring eyes and shackles
• Typical DIY time: 1–3 hours depending on rust and access
• Consider replacing bushings or applying anti-seize during reassembly

Who this is for: This Lonffery hanger kit is designed for trailer owners, mechanics, and DIYers who need a dependable, full replacement for worn hangers on single-axle trailers using 1-3/4" double-eye leaf springs. It suits boat trailers, utility trailers, campers, and contractors' trailers in the 2,000–7,000 lb capacity range who want correctly sized hangers and complete hardware in one purchase.
