Install Rear Trailing Arms

PST

Photography by John Kiewicz

Installing aftermarket boxed rear trailing arms is an effective suspension mod that most car crafters can do themselves--it's very common on rear-coil-sprung GM cars such as A- and G-bodies from 1964-1988. But as basic as this upgrade is, there is some stuff to consider that the instructions don't talk about. Recently, we installed a set of PST lower rear trailing arms on an 1987 Buick Grand National (a GM G-body), and here we'll tell you what the instructions don't. The arms themselves are different for the late-model A- and G-bodies than they are for the 1964-1972 A-body cars (Chevelles, Skylarks, and such), but the installation procedure is very similar. It's also the same for the arms from the many companies that sell 'em.
