Why should you get prothanes?Production vehicles are built using rubber motor mounts. Rubber components are on the soft side to accommodate the typical car and truck buyer, and they tend to deteriorate rapidly. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane inserts can correct these conditions, while improving drivability.Fits onto all 4G63 1990 - 1994 DSM M/T Only; front and rear inserts do now work on Automatic Transmissions!Model Number: 13-1901 Application: 1990 - 1994 Mitsubishi Eclipse & Eagle Talon Turbo M/T
