Kingpin GO-NO GO (Class 8 Trailer) Aluminum Inspection Gauge
This gauge is designed as an aid to determine the wear level and compliance of a Trailers Kingpin during routine inspections according to SAE J700 Surface Vehicle Standard and J2228 Surface Vehicle Recommended Practice.
Gauge details
This gauge is specially designed with two separate wear level indication for both the Throat and Jaw contact areas. The two levels “Recommended” and “Fail” allow the technician to easily identify the condition of the Kingpin.
If the Kingpin does not enter either stage at any position it is within normal operational parameters. If the Kingpin enters the recommended level, it is still within operational standards but should be scheduled for preventative maintenance as the pin is getting close to the out of compliance level. If the kingpin enters the “Failed” stage the kingpin must be repaired before the trailer is put back into service.
Gauge Inspection Instructions:
STEP 1
Use the side of the gauge to check for proper height and squareness of the Kingpin.
STEP 2
Slide gauge over kingpin.
STEP 3
Check both the Throat and Jaw contact area with corresponding sections of the gauge. (Rotate 360 degrees to check all sections of the diameter)
STEP 4
If the kingpin enters either the Recommended or Fail thresholds schedule repairs.

Don’t Ignore the Kingpin
Anytime you have metal in contact with metal you get wear and damage. The truck’s fifth wheel and the trailer’s kingpin are both composed of high strength steel. The more the connection between the truck and trailer is stressed the higher the wear rate. Most shops don’t have welders that are certified to complete a structural repair on a trailer therefore they ignore the kingpin and focus on the fifth wheel. This solves 50% of the problem, which is like solving 0% of the problem. If the KINGPIN is damaged or worn excessively it will not function properly and cause damage to the new or repaired fifth wheel when connected.
By tracking kingpin wear rates and proactively repairing equipment you can:
- Keep wear rates manageable
- Predict future repair needs
- Reduce equipment downtimes
- Save huge sums of money
Kingpin Specialists provides an engineered solution that will restore your kingpins to their original equipment specifications and prevent the wear and damage from spreading to other units.
