I got in touch with Denny at HDK and asked if i could swap my parts with the Drag Racing parts, got them back and also the upper control arms with the hiem joints and spacers. Also got QMP ultimate upper ball joints with 1” extra long studs. I need to clearance the chassis so the upper arm swings freely to the bump stop mount without hitting. I really like the HDK parts. I want of front end suspension travel with free movement.
