This M1 monotube rear shock pair fits the 2002-2006 Chevrolet Avalanche 1500 in both 4WD and RWD, along with GMC C15/C1500, C15, K15/K1500, and K15 Suburban applications spanning 1970-1978 in the trims listed in the fitment section. The 46mm monotube body uses a digressive piston with self-adjusting deflective-disc rebound and compression control, riding on an 18mm case-hardened chrome rod inside a 2-inch extruded tube.
