I put a set of 31 spline Mosers in an 80 ElCamino 3000 lbs. Street legal w/full spool drove it an average of 50-75 miles a week on the street and occassional trips to the track. Leaving on the bumper 1.30 60' - 8.90s @ 154 mph small block car and axles are just now showing signs of twist.
Moser worked for me , no complaints after taking them way beyond their intended use and these where "street axles". [/url]
