Don't let the word economy scare you .It's a excelent quality unit and plenty strong enough. Iv'e never had a heim failure with these. The A-arm will rip off before the heim fails. lol! QS components is a excellent company to deal with. They have every thing you need.
Advice: Order all the heims and bungs with right hand threads. Your not needing left hand as your not using them to adjust length of a track bar or pan head. The heat from the welding process distorts the bung threads The bungs need to chased with a starter tap after being welded in or you run a big chance of stripping them out. Right hand 1/2-20 taps are a dime a dozen. left hand taps can be difficult to find and normaly a special order. Keeping everything right hand just makes life easier.
