UMI Performance's TH400 transmission crossmember for 1998–2002 Camaro and Firebird lets you fit a TH400 while retaining a stock-style torque arm. Built from DOM mild steel tubing with 0.188" mounting plates and a 0.250" machined torque arm mount, it installs as a 100% bolt-in replacement using factory holes and includes necessary hardware. Use a one-piece polyurethane bushing when pairing with a stock torque arm.
