GS-2125DLT Grease Seal – Fits 145 UT Spindles
For 5,200 lb – 7,000 lb Trailer Axles
The GS-2125DLT grease seal is specifically designed for hubs using a 145 UT spindle, commonly found on 5,200 lb, 6,000 lb, and 7,000 lb trailer axles.
This seal will NOT fit 3,500 lb axles.
🛞 What Is a 145 UT Spindle?
A 145 UT spindle features:
• 2.125″ seal surface (inner diameter)
• Larger bearing configuration than 3,500 lb axles
• Commonly paired with 6-lug or 8-lug hub assemblies
• Used on medium- to heavy-duty equipment and utility trailers
If your hub uses a 2.125″ inner diameter grease seal, it is very likely a 145 UT spindle.
✅ Compatible Axle Ratings
✔ 5,200 lb trailer axles
✔ 6,000 lb trailer axles
✔ 7,000 lb trailer axles
Commonly found on:
• Equipment trailers
• Car haulers
• Dump trailers
• Heavy-duty utility trailers
• Tandem axle setups
✘ 2,000 lb axles
✘ 3,500 lb axles
✘ Light-duty utility trailer spindles
✘ Automotive hubs
📏 How to Confirm Fitment
Before ordering, verify one of the following:
1️⃣ Measure the spindle seal surface — it should measure 2.125″
2️⃣ Check your hub spec sheet for a 2.125″ ID grease seal
3️⃣ Confirm your axle rating is 5,200–7,000 lb
If those match, this seal is correct.
🔧 Why Proper Fit Matters
Using the correct 145 UT seal ensures:
• Proper grease retention
• Bearing protection
• Water and dirt exclusion
• Longer hub life
• Safe highway operation
Installing the wrong seal can result in grease leakage or bearing failure.
