Welcome back Carolyn. The Lippert Trailer Axle Beam with Super Lube Spindles item # LC93PK has a 2-3/8" diameter axle shaft. This is a 3,500 lbs capacity, 4" drop axle, with a 85" hub face and 70" spring centers.

The Lippert Trailer Axle Beam item # LC93PK has the standard #84 spindles so long as your hubs use item # L68149 inner and item # L44649 outer bearings they'll be able to be reused. This axle has spring seats mounted in the underslung position.

I recommend picking up two of the Lippert U-Bolt and Nut Kit for 3,500-lb Trailer Axles item # LC27RP and two of the U-Bolt Plate item # TRTP238175. The U-Bolts on your axle will need to be replaced when you install the Lippert Trailer Axle Beam item # LC93PK. The bolts and nuts are only meant to be torqued down upon the initial installation. The hardware likes to fatigue and bend so you won't be able to torque the old ones to the right specs.

What do you typically haul with your utility trailer? Feel free to answer this and throw in any other questions you have, where it says Add Comment.
