GM Chevy Street Stock 1973-88 GM Heavy Duty Upper Rear Control Trailing Arm
Part Number: 2D27C508Description
Stock stamped control arms flex and twist under load, causing wheel hop and unpredictable handling—especially problematic in street stock racing where consistency determines winners. This heavy-duty upper rear control trailing arm replaces that weakness with a rigid, purpose-built component that maintains precise wheel control through hard cornering and acceleration. If you're serious about eliminating suspension compliance and improving lap times, this is the upgrade your rear end needs.
