Part Number: 8000-95-35-KIT TRUE 8K Dexter 95" Hub Face / 3.5" Tube
Overview
This Dexter 8,000 lb bare trailer axle beam is built for heavy-duty trailer service where a 95" hub face, 3.5" axle tube, EZ Lube spindle setup, and 4-bolt brake flange are required. It is a TRUE 8K axle configuration intended for compatible hub, drum, bearing, seal, and 12.25" x 3.375" brake systems.
R&P Service Insight
Axle replacement depends on matching the actual running gear measurements, not just the weight rating. Confirm the critical dimensions before ordering.
- Hub Face Match: This axle uses a 95" hub face measurement.
- Brake System Match: Designed around 12.25" x 3.375" brake compatibility such as Dexter 8-285 style hub and drum applications.
- Perch Notice: SS-350 spring perches are included loose and must be positioned and welded before the axle is placed into service.
R&P Knowledge Hub
Compatibility: TRUE 8K Dexter axle beam for compatible 8,000 lb trailer running gear using 25580 inner bearing, 02475 outer bearing, and 12.25" x 3.375" brake systems.
Trailer / System Fit: Useful for wider deck trailers requiring a 95" hub face and heavy-duty 3.5" axle tube.
Installation Notes: Verify hub face, brake flange-to-flange, bearing shoulder-to-shoulder, spindle length, spring center, brake size, bearing set, and seal size before installation.
Performance Insight: A cambered straight axle is designed to carry load correctly when installed with the arch facing upward in the center.
Brand & Fitment Note
Selling Brand: Dexter axle beam sold by R&P Carriages.
Application Reference: Dexter and related component names in this listing describe verified axle style, compatible running gear, or application reference based on the supplied specifications.
What This Means: This listing is for one Dexter 8,000 lb bare trailer axle beam with two loose SS-350 spring perches.
Before Ordering: Verify all measurements, brake style, bearing set, seal size, hub/drum compatibility, spring center, and required components before installation.
R&P Repair Insight
Do not rely on trailer deck width alone when replacing an axle. The old axle, existing spring setup, hub face, and running gear measurements are the safest comparison points.
- Measure First: Confirm the 95" hub face and related spindle dimensions against the axle being replaced.
- Confirm Brakes & Drums: This axle is set up for compatible 8K hub/drum and 12.25" x 3.375" electric brake systems.
- Check Seal History: Typical seal size is 2.25", but some older trailers may use 2.125". Verify before ordering seals.

Important Axle Perch Notice
Spring Perches Are Included Loose
This listing includes the axle beam and loose spring perches / spring seats. The spring perches are included as separate pieces. Included does not mean welded.
Spring perches ship loose by default. They are not welded to the axle tube before shipment unless the customer specifically requests perch welding in the order notes, provides the correct Spring Center measurement, and R&P confirms the weld-on request before the axle ships.
Repetition matters: If the listing says “spring perches included,” that means loose spring perches are included with the axle. It does not mean the spring perches are already installed, welded, or ready for towing.
Do not install or tow with loose spring perches. The perches must be measured, positioned, squared, and welded to the axle tube before the axle is placed into service.
When Will R&P Weld the Spring Perches?
R&P may weld the spring perches before shipment only when the order clearly gives us the information needed to do it correctly.
- The customer must request welded spring perches in the order notes.
- The customer must provide the Spring Center measurement.
- R&P must confirm the weld-on request before shipment.
Default rule: If the order does not clearly request welded perches and does not provide a Spring Center measurement, the spring perches ship loose.
How to Find Your Spring Center Measurement
Spring Center is the distance from the center of one leaf spring to the center of the opposite leaf spring. This is the measurement used to locate where the spring perches need to be welded on the axle tube.
- Best method with old axle: Measure from the center of one existing spring perch / spring seat to the center of the opposite spring perch / spring seat.
- Best method from the trailer: Measure from the centerline of the left leaf spring pack to the centerline of the right leaf spring pack where the axle sits.
- Leaf spring center bolt method: Measure from the center of the center bolt / locating pin on one spring pack to the center of the center bolt / locating pin on the other spring pack.
- Do not measure outside-to-outside. Spring Center is a center-to-center measurement.
- Do not guess from deck width. Deck width can be helpful context, but it is not a substitute for the actual Spring Center measurement.
Axle Measurement Diagram
Use the axle measurement diagram below as a visual reference while confirming axle dimensions and installation details. Spring Center must still be measured center-to-center at the trailer’s leaf springs or existing spring perches.
Why Welding the Perches Matters
This image shows a real-world installation problem where loose spring perches were not welded before use and brake wiring was torn out. This is exactly why the axle must not be installed, towed, or placed into service while the spring perches are still loose.
Loose perches can allow the axle to move or rotate out of its intended installed position. That can damage brake wiring, brake components, suspension parts, tires, and the trailer. The perches must be properly welded before road use.
| Question | Answer |
|---|---|
| Are spring perches included? | Yes. The SS-350 spring perches / spring seats are included as loose parts. |
| Are the spring perches welded on by default? | No. They ship loose by default. |
| Can R&P weld the perches before shipping? | Only if the customer requests it in the order notes, provides the correct Spring Center measurement, and R&P confirms the request before shipment. |
| What measurement is needed for welding? | Spring Center: center of one leaf spring / spring perch to the center of the opposite leaf spring / spring perch. |
| Can the axle be used with loose perches? | No. Do not install, tow, or place the axle in service until the perches are properly welded. |
| What can happen if perches are not welded? | Loose perches can allow the axle to move or rotate, which can damage brake wiring, brake parts, suspension components, tires, and the trailer. |
| Which way does camber face? | If the axle is cambered, the arch goes up in the middle when installed. |
Order Note Wording Customers Can Use
Customers who want R&P to weld the spring perches should put clear instructions in the order notes before checkout.
Example order note: “Please weld spring perches before shipping. My Spring Center measurement is ____ inches, measured center-to-center.”
Final reminder: Unless the order notes request welded perches, the Spring Center measurement is supplied, and R&P confirms the weld request, this axle ships with loose spring perches.
