Speedway Motors 91034337 Details

You don't have to look any farther for tubular control arms for your Mustang II IFS-equipped hot rod. Our Mustang II control arms are made from full .120 wall, 1" diameter tubing, fixture welded and feature screw-in ball joints and no-squeak rubber bushings. These new generation, no-strut style arms eliminate the strut rod found on stock-style Mustang II IFS systems. The improved, triangulated design provides stability and strength within the arm itself, so you can get rid of that ugly strut rod.

Will work with nearly any stock or aftermarket Mustang II front crossmember (welding is required on most applications). Lower control arm accepts most coil-over shock assemblies. These control arms are 5/8" narrower than stock, which means that they will reduce front track width by 5/8" per side (or 1-1/4" overall) when compared to a stock width control arm. This helps tuck the wheels up under the fenders without having to buy expensive special offset wheels. When using 5/8" narrower control arms, 1" must be removed from each inner tie rod end.
