Description

Generic Trailer Spring: 1_3/4” wide, 5 Leaf, 13_1/4″ (25_1/4″) approx: 3,000 lbs.
Repair or replace your trailer’s suspension with our double-eye leaf spring, also known as an eye-by-eye trailer spring, designed for reliable performance and optimum load carrying capacity on light duty trailers including RVs, campers, utility trailers, boat trailers, and equipment haulers. This is a common style of leaf spring that features an “eye” at both ends of the spring with nylon or brass bushings. This spring mounts either above or below the trailer axle and secures to standard hangers and shackles for a smooth, controlled ride. Built from heat-treated spring steel, each trailer spring is engineered to handle loads while reducing bounce, excessive friction, and sway on the roughest of roads. Whether you’re replacing worn springs, upgrading your suspension, or building a new trailer, these springs offer a perfect combination of strength, stability, and durability. These are available in a variety of leaf counts and weight ratings to match your axle capacity. Our double eye leaf springs are ideal for single, tandem, or triple axle trailer configurations.

US-1075 Technical Specifications

The US-1075 is a 5-leaf trailer spring designed for heavier trailer applications that require a firmer spring pack and approximately 3,000 lbs of load capacity per spring.

Before ordering a replacement trailer leaf spring, compare these measurements with the existing spring and suspension hardware to confirm proper fitment.

Recommended Trailer & Axle Applications

The US-1075 is suited for trailers that regularly operate under heavier loads and need the added support of a 3,000 lb leaf spring.

• Commercial utility trailers
• Enclosed work trailers
• Equipment haulers
• Campers and recreational trailers
• Heavy-use single-axle applications
• Trailers frequently carrying near-capacity loads
• Applications exposed to rough or uneven roads

Its five-leaf construction provides a firmer spring pack that can help improve load support and trailer stability compared with lighter spring configurations.

5-Leaf vs. 4-Leaf: Why Choose the US-1075?

Choosing between a 4-leaf and 5-leaf trailer spring depends on the trailer’s load requirements, suspension setup, and whether a heavy-duty stiff flex spring is needed for added support and stability.

• Increased Stiffness & Sway Control: The fifth leaf creates a firmer spring pack, helping limit excessive body movement when carrying heavier or top-heavy loads.
• Improved Load Distribution: Five leaves distribute suspension forces across an additional leaf, making the US-1075 well suited to frequent heavy-duty trailer use.
• Heavy-Use Durability: The additional leaf can reduce the amount of stress carried by each individual leaf during repeated loaded operation.
• Pack Thickness: At 1.8″, the US-1075 is thicker than many 4-leaf alternatives. Verify U-bolt length and mounting clearance before replacing a thinner spring pack.

For trailers consistently operating under demanding loads, the US-1075 provides a heavier-duty option without changing the standard 1-3/4″ spring width.

Installation & Related Hardware

Proper mounting hardware is important when installing a heavy-duty trailer leaf spring, especially when replacing a thinner 4-leaf spring pack.

Depending on the trailer’s existing suspension configuration, commonly required hardware may include:

• 1-3/4″ wide trailer hanger kits
• 9/16″ x 3″ shackle bolts
• Spring bushings
• Spring plates
• U-bolts sized for the 1.8″ spring pack
• Replacement shackles and equalizer hardware

When upgrading from a 4-leaf spring, check U-bolt length and suspension clearances to account for the thicker US-1075 spring pack.
