The compact 400 Series power steering box utilizes
late model steering technology for your classic. These are a direct replacement
for the original manual steering box and keep perfect alignment with the
OE or aftermarket column. The compact design is closely modeled after the
original manual steering box. With its 13.6:1 ratio (2.75 turns lock to
lock) it has the performance handling of many rack and pinion conversions
without the need for extensive modifications. This box uses the original
MANUAL steering pitman arm. Both the 400 Series & 500 Series
have a ¾" -30 input shaft and use inverted flare hoses (11/16"
-18 pressure fitting & 5/8" -18 return fitting). These are the
perfect solution for your bolt on performance power steering needs!
