Note: These lower control arms will require use of a strut rod and strut rod brackets. We recommend our tubular strut rods (91034322).

Note: Consider our Mustang II Lower Arm bolt kit (91034311-2) for proper installation.


Why go with tubular control arms? The most obvious reason is the looks. Tubular control arms and strut rods give your hot rod a much cleaner and hi-tech appearance than the stock type do. Another bonus is that the tubular control arms are available in 5/8" narrower than stock, which helps tuck the wheels up under the fenders without having to buy expensive special offset wheel. When using 5/8" narrower control arms, 1" must be removed from each inner tie rod end.
Some parts are not legal for use in California or other states with similar laws/regulations
