Details & Inspection Notes
The QA1 R120-250 is a firmer-spring option in QA1's F-100 rear coilover line, pairing a single adjustable coilover with a 250 lbs./in. spring on a 1965-72 Ford F-100. QA1 lists a 4 in. to 7 in. drop range, with the springs finished gray/silver over black powdercoated suspension pieces.
What this kit leaves out
Watts links, rotors, and calipers stay off this parts list entirely, and the upper trailing arm is not part of the box either, so treat brakes and the upper rear linkage as separate purchases if your project needs them. Nothing in the listing calls for bed removal, and the swap is bolt-on.
What comes with it
Trailing arm mount braces ship alongside the lower trailing arms and the on-car panhard bar in one kit, and no welding is listed anywhere in this package.
Is this a stiffer spring than other options in this line? QA1 lists this 250 lbs./in. rate as a firmer choice than the softer-rate version in the same F-100 rear kit lineup.
Is a watts link included? No, a watts link is not part of this kit.
