Improve the handling of your classic muscle car with ORP's Track Roller Spring Perches. Stock perches use rubber as the bushing between the perch and the perch-mounting shaft which greatly increases the effort required for your suspension to move. Our track roller spring perches use two sets of roller bearings to greatly reduce this resistance which improves ride quality, responsiveness to the road, and improved handling. Opentracker Track Roller Spring Perches fit: 1964-1973 Mustang - 1967-1973 Cougar 1960-1970 Falcon - 1960-1974 Comet 1966-1971 Fairlane - 1968-1971 Montego 1968-1971 Torino - 1970-1977 Maverick 1962-1967 Chevy II/Nova $299/pair - E-mail us at opentracker@sbcglobal.net to order this custom made part.
