Genuine Lippert replacement shackle link for compatible double-eye leaf spring trailer suspension systems. Engineered to OEM dimensions so it drops in without modification. If your current shackle is bent, cracked, or worn at the bolt holes, this is the part you need.
Shackle links are a critical but often overlooked component of trailer suspension. They connect the rear eye of the leaf spring to the fixed rear hanger bracket, allowing the spring to flex and extend under load. A worn or damaged shackle link causes sloppy handling, uneven tire wear, and in severe cases, spring separation from the frame -- a road hazard on any tow.
The Lippert 133207 is a direct OEM-style replacement built to the same 3-1/8" center-to-center specification as the original. At 0.224" thick steel, it matches the structural geometry Lippert engineers into their axle and hanger systems. This is not a universal aftermarket approximation -- it is the correct replacement for compatible Lippert-equipped trailers.
3-1/8" bolt-hole spacing matches original Lippert hanger geometry for drop-in fit.
0.224" thick stamped steel provides strength and durability under repeated suspension cycling.
Designed for double-eye (multi-leaf) spring setups common on single and tandem axle trailers.
Sourced directly from Lippert -- same part that ships on new trailers from the factory.
In a leaf spring suspension system, the spring is anchored at the front to a fixed hanger pin and at the rear to a moveable shackle. The shackle link is the two-hole plate (or set of plates) that forms that rear pivot. As the spring compresses and rebounds, the shackle pivots to accommodate the change in spring arc length.
Because the shackle link is always in motion and carries a portion of the trailer's gross weight, the bolt holes elongate over time and the steel fatigues. Inspecting shackle links at every pre-trip check is a standard part of responsible trailer maintenance. Replace them in pairs (both sides of the axle) for balanced suspension geometry.
On a single-axle trailer, shackle links mount at both the front and rear hangers. On a tandem-axle trailer with an equalizer, shackle links typically appear only at the front and rear fixed hangers -- the center pivot uses an equalizer arm. Verify your hanger layout before ordering to confirm you need a shackle link versus an equalizer bracket.
This listing is for the shackle link plate only. Shackle bolts, nuts, washers, and cotter pins are NOT included. U-bolts, hanger brackets, leaf springs, and equalizers are sold separately. Verify your existing center-to-center bolt spacing before ordering.
