14:1 power steering that bolts in. No cutting your column.

Why this kit
Built to fit like a factory part, because it uses them
Other conversions make you cut the column, swap hoses or bolt on parts that look out of place under the hood. Ours doesn't.
No column modification
Our direct-fit coupler, assembled by certified welders, replaces the stock coupling on virtually every Mopar and keeps the original safety plunge.
Keeps your factory hoses
Specific pressure and return fittings let you retain factory-style hoses, with an OE-style keyway pump and pulley.
The complete kit
Crank pulley and belt are included when other kits leave them out. One order, one install weekend.
Looks like real Mopar
Original-style pump pulley and bracketry. It performs like a modern car and looks right with the hood up.
From owners
What it feels like on the road
“This steering kit is by far the best upgrade I have done to my 71 Challenger vert. The car steers and handles great. 80 mph and straight no wandering at all.”
“I love having less steering effort and the quicker steering response. Using your steering column adapter, I did not have to modify my original steering column which was a plus.”
“Drove the car around town and highways… I should have done the swap long time ago!! Now the car is great and more fun to drive!”
