Verify center-to-center dimension and bolt pattern against the existing torque rod before ordering. Replace the upper and lower torque rods on the same axle as a set when one fails — the matched lengths keep pinion angle correct. Inspect frame brackets and crossmember for cracking when an OE torque rod has separated.
