Tgkjmad Trailer Bearing Kit 7000 lb Tandem Axle — 8-Lug #42 Spindle, Complete Repack Kit (25580/14125A)

This kit supplies everything needed to service tandem-axle trailers rated around 7,000 pounds: matched 25580 inner and 14125A outer bearings, precision races, double-lip grease seals, dust caps and all mounting hardware. It’s made to fit common axle standards including Dexter, AL-KO and other OEM-style hubs, and works with both EZ-Lube and standard spindle configurations. The components are crafted from alloy steel and engineered seals to resist grease loss and support heavy towing loads when properly installed and maintained.

How do I know this kit fits my trailer?

Verify your existing bearing and spindle specs before ordering: this kit is built for 8-lug hubs with 1-3/4" x 1-1/4" #42 spindles and uses 25580 inner and 14125A outer bearings. If your trailer lists those bearing numbers or matches the spindle size, the kit is compatible.

• Check hub lug count: 8-lug hubs required
• Confirm spindle size: 1-3/4" x 1-1/4" #42
• Match bearing numbers: 25580 (inner) and 14125A (outer)
• Works with Dexter, AL-KO, Quality and similar axles

What parts are included and why they matter?

The kit arrives ready for a full hub repack and bearing swap with bearings, races, grease seals, dust caps and fasteners. Having all matching components ensures correct fit and reduces the risk of mixing incompatible parts during service.

• 25580 inner bearings and 14125A outer bearings for matched rolling support
• Precision races machined to seat bearings securely
• Double-lip NBR and steel grease seals (10-10 / 10-36 specs) to limit leakage
• Dust caps, spindle nuts, cotter pins, washers and rubber plugs for a complete assembly

How does this kit improve towing reliability?

Using matched alloy-steel bearings and proper seals helps maintain smooth rotation and load support, reducing heat and wear when trailers carry heavy loads. Proper installation and regular maintenance are still essential for long service life.

• Alloy-steel bearings resist wear under load for consistent wheel rotation
• Seals designed to keep grease in and contaminants out
• Included hardware ensures correct torque and secure assembly
• Reduces downtime by supplying all needed replacement items in one purchase

How do I maintain components after installation?

After installation, inspect hubs periodically for noise, heat or grease leakage, and repack or replace seals as needed. Routine checks keep your trailer safer on the road and extend the life of bearings and hubs.

• Grease hubs at recommended intervals, especially after water exposure
• Check bearings for play or grinding and replace when worn
• Inspect seals and dust caps for damage and replace if leaking
• Re-torque spindle nuts to manufacturer specs after initial road test

Who is this for: This Tgkjmad Trailer Bearing Kit is intended for DIYers, fleet technicians and marine or utility trailer owners who maintain 7,000 lb tandem-axle trailers with 8-lug, #42 spindles. It’s ideal when you need a full hub repack set that matches common OEM bearing and seal numbers and prefer a single kit that includes every part required to complete the job.
