QA1 and Viking share similar design origins.

I have a BBF engine with dual adjustable QA1's:
Front (A Arm) - QA1 Proma Star DD404 (2x) /Springs = 350 lbs. (2x)
Rear (Jag IRS) - QA1 Proma Star DD403 (4x) / Springs = 300 lbs. (4x)

At the same time, installed new Howe Racing Ent. ball joints.

Tracks the road solid like it's on rails now.
