Details & Inspection Notes
Step up from a single-adjustable setup and the 52346-D400 is where QA1 puts double-adjustable coilovers on its Mopar front conversion, tuning compression and rebound on their own dials, still at a 400 lbs./in. spring rate. Ductile iron spindles hold stock ride height, and the fitment list covers Charger, Road Runner, Super Bee, and GTX B/E-body cars.
What to check before buying
Whatever engine goes under the hood, source its mounts on their own; this conversion does not bundle them in, regardless of whether that is a small block, a big block, or a Hemi swap. A sway bar and brake hardware are likewise left off the parts list.
What comes with it
Tubular steel upper and lower control arms carry their own ball joints, a crossmember finished black powdercoated supports the front end, and a power-assisted rack-and-pinion unit handles turning; tie rod sleeves with inner and outer ends finish the steering linkage. Drop tops out at 2 inches, and none of it needs a welder.
Are engine mounts included? No, buy those to suit whatever engine is going in.
Is this single or double adjustable? Double adjustable, with compression and rebound tuned on their own.
