Hubface & Spring CenterHubface & Spring Center

Spring Center & Hubface

The hubface is the distance from the outside of one hub to the outside of the hub on the opposite side of the axle. Spring center is measured from the center of the spring seat on one side of axle to the center of the spring seat on the other side of the axle.

The hubface is the distance from the outside of one hub to the outside of the hub on the opposite side of the axle. Spring center is measured from the center of the spring seat on one side of axle to the center of the spring seat on the other side of the axle. 

Bolt Pattern

The number of bolts or lugs per wheel and the diameter of the circle the bolts are arranged in make up a trailer wheel hub bolt pattern. To measure a 5-lug bolt pattern, pick a bolt and measure from the outside of the bolt. Then, skip a bolt and measure to the center of the next bolt. To measure a 4, 6 or 8-lug bolt pattern, measure center to center of two bolts directly across from one another.

Spindle StyleSpindle Style

Spindle Style

Spindles provide a surface for your wheel bearings and wheel hub to rotate around. A straight axle has a completely straight design, while a drop axle makes the wheel hub higher than the axle tube, allowing the trailer to sit lower to the ground.

Spring OrientationSpring Orientation

Spring Orientation

Overslung and underslung describe the ways in which the trailer leaf springs attach to the axle beam. Overslung leaf springs sit on top, or “over” the axle, while underslung leaf springs sit beneath, or “under” the axle. Trailer height, clearance from the axle to the frame and driving stability are all affected by overslung versus underslung leaf springs.

Hub Style

A brake hub allows for electric, hydraulic drum or disc brakes, while an idler hub has no provision for a trailer braking system. 

Weight Capacity

Knowing your trailer weight capacity helps you understand your towing limitations. We build a full line of reliable 2-12K spring axles to meet unique specifications for a wide range of utility trailers, including open and closed cargo, teardrop and travel trailers. Our dependable 2-7K torsion axles are ideal for cargo, marine, agricultural, equestrian and purpose-built trailers.

The Advantages of Super Lube

Standard on all Lippert axles up to an 8,000-lb. capacity, our Super Lube system makes changing grease easier and cleaner. This time-saving lubricant requires no disassembly of wheels or hubs and fills the entire bearing cavity with grease, allowing for complete submersion. Pumping new grease through zerk purges old grease for a complete repack and offers better long-term protection over standard hubs.
