As well as our non adjustable factory replacement arms, ARC also offer these adjustable tubular arms. Manufactured from 4130 tube with a 3/4" UNF urethane bushed rod end at the chassis end, these arms are the ultimate for any tough car street car. The rod end allows for preload adjustment, and being adjustable at one end only, the arms cannot come undone inadvertantly. These arms feature our new 45 degree laser cut and CNC folded bracket for unsurpassed accuracy and to provide more clearance to the housing mounted bush. These arms are jig assembled to ensure fuss free installation. Hammers not required!
