Aeagle 5-Leaf Double-Eye Trailer Spring Kit — 3,000 lb per Spring, 25-1/4" Length for 3" Round Axles, 2-Pack with U-bolt Kit

Aeagle 5-leaf double-eye trailer spring kit provides 3,000 lb capacity per spring and a complete U-bolt installation set for 5200–6000 lb trailers using 3" round axles.

This heavy-duty replacement package includes two 5-leaf, double-eye springs designed for round trailer axles, plus a full U-bolt kit so you can swap worn suspension components in one service session. Built with anti-rust coating and precision dimensions, the kit is intended as a direct-fit substitute for SW5-style springs (not for square axles). Each spring is rated for 3,000 lb load capacity and comes pre-tested to ensure dependable performance right out of the box.

What are the exact dimensions and capacity of these springs?

The springs measure 25-1/4" eye-to-eye, with a free height (open) of 3" and a leaf width of 1-3/4". Each assembly contains five leaves and uses a 9/16" bushing diameter. Rated capacity is 3,000 lb per spring, making the pair suitable for trailers in the 5,200–6,000 lb gross range when matched to the correct axle and installation hardware.

• Eye-to-eye length: 25-1/4"
• Free open height: 3"
• Leaf width: 1-3/4"; 5 leaves; 9/16" bushing
• Capacity: 3,000 lb per spring (pair supports trailer rating when installed per axle spec)

What hardware is included and how does the U-bolt kit fit?

The kit supplies the U-bolts and mounting hardware needed for a clean replacement on a 3" round axle. Included items match common trailer assembly configurations so you won't need to source extra parts for a standard swap. Note the U-bolt diameter and thread length to confirm fit on your axle tube.

• 4 × 7" long U-bolts, 1/2" diameter
• 2 × tie plates sized for 1-3/4" or 2" leaf springs
• 8 × 1/2"-20 hex nuts; U-bolt thread length: 2"
• Intended for 3" round trailer axles (not compatible with square axles)

How durable and corrosion-resistant are these springs?

Aeagle applies an anti-rust coating and selects robust steel to increase service life under road conditions. Components are inspected prior to shipping to reduce early failures. Proper torqueing and horizontal nut tightening help preserve fitment and longevity after installation.

• Anti-rust coating for improved corrosion resistance
• High-quality raw materials chosen for strength and durability
• Inspected and tested before shipment; 12-month warranty included
• Install note: tighten nuts horizontally to avoid installation issues

Will these springs replace my SW5 parts and what should I check before buying?

These springs are made as replacements for SW5-style double-eye 5-leaf springs intended for round axles. They are not compatible with square axles, so confirm your axle tube diameter and spring pad dimensions before purchasing. Cross-check eye-to-eye length, free height, and leaf width to ensure correct ride height and load capacity for your trailer.

• Designed to replace SW5-style springs for round axles only
• Not compatible with square axle designs
• Verify axle diameter, spring pad size, and eye-to-eye length first
• Follow torque and installation guidance for best results

Who is this for: This Aeagle kit is ideal for trailer owners and mechanics needing a complete, cost-effective spring swap on a 3" round axle trailer rated approximately 5,200–6,000 lb. Choose this set if you want matched springs with the accompanying U-bolt hardware, pre-tested parts with corrosion protection, and a 12-month parts warranty for peace of mind during routine suspension maintenance.
