Do all Cobalt use the same steering rack?
Just about everything from the FE5 suspension and steering will fit on an FE1/FE3. Also rack spacers are recommended for all Cobalts. OTTP even offers different sizes for lowering amounts.I believe they do all fit into all the models, but are different for the FE1, and FE3/FE5 due to the suspension differences and location of things. It is likely for steering geometry and to reduce bump steer. Like when you lower an FE1 suspension, it has been recommended to used spacers on the steering rack from what I’ve seen.
