So-Cal 70503 New Traditionalist Forged Steel I-Beam Front Axle 47"
So-Cal 70503 stock plain forged steel Ford 4" drop axle measures 47" through the kingpin centers and 36½" at the 2 1/4” spring perch boss. 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, and matches Ford specs, so when it's time to install reproduction parts, there's no problem.
The forged dropped axle is the cornerstone of the SO-CAL family of chassis components. SO-CAL's engineering staff spent the better part of three years refining a design that takes into account the idiosyncrasies of a reproduction part, that must first work with original Ford components. This new forged 1045 heat treated steel 4" dropped axle does that and more. The real test is trying to install stock spindles and having them go lock to lock.
This axle is offered in five finishes; plain, plain with drilled web, chrome plated, plain with pre-polished drilled web (use your plater) and chrome plated with drilled web. 2" Spring perch boss is available in both lengths and styles.
