A direct-fit replacement bronze bushing for trailer leaf spring eyes, equalizers, and axle hanger attaching hardware. Sized for 9/16" wet bolt applications on 1-3/4"-wide spring suspension systems. Sold as a single bushing.
The Lippert 126171 is a genuine OEM-spec bronze leaf spring bushing designed to replace worn or damaged bushings in compatible trailer and RV suspension systems. Bronze bushings at the spring eye and equalizer pivot points take the brunt of road stress, vibration, and load cycling. When they wear out, you get slop in the suspension, uneven tire wear, and metal-on-metal contact that accelerates damage to hangers and axle brackets.
This bushing is precision-sized at 9/16" inside diameter to accept standard 9/16" wet bolts (greaseable carriage bolts) and measures 1-3/4" in length to match the spring width on compatible Lippert and aftermarket axle/hanger setups. Bronze construction provides natural lubricity, corrosion resistance, and long service life compared to nylon or plastic substitutes.
Self-lubricating bronze alloy resists corrosion and wear far longer than nylon or plastic bushings under road load and weather exposure.
9/16" ID matches standard wet bolt diameter. 1-3/4" length fits spring width precisely to prevent side-load slop.
Suitable for leaf spring eye, equalizer pivot, and axle hanger attachment points on compatible trailer suspension setups.
OEM part number 126171 (vendor ref 71-3836). Correct spec from the source -- no guessing on fit or material grade.
In a tandem or triple-axle trailer suspension, bronze bushings are installed at three key points:
All three positions use the same bushing dimension on many Lippert-equipped trailers, which simplifies your parts order -- measure your existing bushings before ordering to confirm the 9/16" x 1-3/4" size is correct for your specific rig.
Bronze bushings tolerate higher loads, handle heat from road friction better, and last longer under the grit and moisture that trailer suspension sees. They also work correctly with grease -- nylon bushings can swell or soften when lubricated with certain grease types. If your original equipment used bronze, replace with bronze.
Bushing replacement is a straightforward job for someone comfortable with trailer suspension work, but does require safely supporting the trailer frame and removing spring load from the axle before pulling wet bolts.
This bushing is sized for 9/16" wet bolts (greaseable carriage bolts with a zerk fitting). If your suspension uses a different bolt diameter -- 1/2" is common on lighter trailers -- you need the corresponding bushing ID. Measure your bolt shank before ordering.
Inspect suspension bushings at every tire rotation or at least once per season. A bushing worn to the point of metal-on-metal contact will damage the hanger bracket bore -- a far more expensive repair. Early replacement is cheap insurance.
