Keep your steering linkage tight and precise with the Mevotech Supreme Idler Arm MK6149. It installs at the front of the steering linkage as a direct-fit replacement for many 1973–1974 GM full-size and intermediate cars, including the Chevrolet El Camino and Monte Carlo, Buick Century, Electra, LeSabre, Regal and Riviera, Oldsmobile 98, Cutlass and Delta 88, and Pontiac Bonneville, Catalina, Grand Prix and LeMans, plus additional 1973 Chevrolet models — see the Buyer's Guide tab for the full list.
An idler arm pivots on the frame to support and guide the steering linkage opposite the pitman arm, helping keep the center link and tie rods aligned so the wheels track true. If a worn idler is the cause of loose, wandering steering or excess play, this replaces it.
