Details & Inspection Notes

QA1's 52346-S400 is the single-adjustable sibling to the double-adjustable 52346-D400, running the same 400 lbs./in. spring rate but with compression and rebound tuned together rather than on separate dials, sized for 1966-74 Dodge Charger, Coronet, and Plymouth Road Runner and GTX models.

What to check before buying

Either factory-style or aftermarket brakes bolt up fine, but none ship in the box, so figure out your rotor and caliper plan before checkout. Separately, an engine mount purchase is needed too, picked to suit whatever sits under the hood.

What comes with it

A crossmember in plain steel, tubular upper and lower arms, and a power-assisted rack-and-pinion unit replace the stock torsion-bar hardware, finished out with tie rod ends and a full hardware kit for bolting everything into place; no welder is needed anywhere in the install.

Does this include disc brakes? No, rotors and calipers are sourced on your own, factory-style or aftermarket.

How does the adjustment work? It is single adjustable, one dial rather than separate compression and rebound settings.
