The latest addition to the SO CAL family of chassis components is our forged dropped, axle, which is now the cornerstone of the product line. SO-CAL's engineers refined a design that takes into account the idiosyncrasies of a reproduction part that must first work with original Ford spindles. This new 4" dropped axle does that and more. The real test is trying to install stock spindles and having them go lock-to-lock. SO-CAL's axle shows a 30% improvement over the competition in turning radius alone. So when it comes time to install reproduction parts, there's no problem. The axle measures 47" through the kingpin centers, 34" at the 2-1/4" inch thick spring perch boss and fits a 29-1/4" spring. It is offered in five styles; plain, plain with drilled web, chrome plated, plain with pre-polished drilled web (use your plater) and chrome plated with drilled web.
