Hey Craig. The #42 E-Z Lube Spindle w/ Flange item # TRU37FR, you were looking at, has a 1"-14 thread size. This spindle fits 5,200-lb - 7,000-lb trailer axles. It has a 5 bolt brake mounting flange. The distance from the flange to the tip of the grease fitting is 7-1/2". To the end of the threaded part is 7-1/4".
What kind of trailer do you have?

Hey Craig, did the #42 E-Z Lube spindle with the 1-14 thread size fit your trailer axle the way you needed? Your update could make it easier for others working with similar 6,000-lb setups.
