Otoolling leaf spring hanger kit 4-5/8" Double Eye 2-piece steel trailer axle brackets

This Otoolling hanger set supplies two identical front/center/rear brackets intended for routine trailer suspension repairs and upgrades. Each hanger is formed from 1/4" low-carbon steel with a plain finish and engineered to accept single-leaf springs that measure 1-3/4" wide. The 4-5/8" height and 9/16" bolt hole size match common trailer hardware, letting you replace worn hangers without extensive modification. Sold as a matched pair, the set helps preserve balanced suspension geometry when servicing more than one mounting point.

How do these hangers match common leaf spring dimensions?

These brackets are sized with practical trailer standards in mind: the hanger's inner pocket is 1-7/8" to accommodate 1-3/4" single-leaf springs, and the overall height is 4-5/8" to align with typical spring-eye positions. That dimensional approach reduces the need for fabrication or adaptors during installation.

• Inner pocket clearance: 1-7/8" for 1-3/4" springs
• Overall hanger height: 4-5/8" to match spring-eye geometry
• Bolt hole diameter: 9/16" to fit standard suspension bolts
• Two identical pieces for matched front/center/rear replacement

What materials and construction details improve durability?

The hangers are stamped from 1/4" low-carbon steel, delivering solid rigidity while remaining straightforward to weld or bolt into place. The steel thickness and bolt-hole sizing are selected to resist bending under normal trailer loads and to accept high-strength fasteners for a dependable joint.

• 1/4" plate steel body for structural strength
• Low-carbon composition for predictable forming and welding
• Plain steel finish suitable for primer or paint coating
• Standard 9/16" hole for secure bolt fitment

Will this kit work for different mounting positions on my trailer?

Yes. The pair can be used as front, center or rear hangers depending on your trailer's layout, offering flexibility for a variety of maintenance tasks. Using matched hangers helps maintain level suspension and consistent ride characteristics across the axle positions.

• Suitable for front, mid, or rear spring mounting points
• Identical pair reduces mismatch between mounting locations
• Can be used for single-axle or multi-axle trailer repairs when geometry fits
• Works with common spring eye spacing and bolt sizes

How straightforward is installation for a DIY mechanic?

Installation is generally simple for those comfortable with basic trailer work: remove the old hanger, align the new bracket, and fasten it with a 9/16" suspension bolt or weld in place if preferred. The hangers are dimensioned to minimize trial-and-error fitting, but confirm measurements against your trailer before committing.

• Remove worn hangers and clean mounting surface
• Align hanger to spring eye and check bolt hole alignment
• Fasten with appropriate 9/16" grade bolts or tack-weld for permanent fit
• Paint or treat plain steel finish after installation to prevent corrosion

Who is this for? The Otoolling two-pack is aimed at trailer owners, repair shops, and DIY mechanics who need dependable replacement hangers for single-leaf spring suspensions. It fits common spring sizes and bolt hardware, so it’s a practical option for routine maintenance, restoration projects, or when replacing multiple hangers to restore balanced suspension alignment. If your trailer uses 1-3/4" single-leaf springs and 9/16" suspension bolts, this set offers a matched pair to simplify repairs and help maintain consistent performance across axle mounting points.
