Does anyone know if the shocks from a rev will fit in a summit ZX chassis? My shocks are 15" center to center and it appears that rev shocks are about 17". Are the diameters of the mounting holes the same?
No, Without serious modification to your front suspension they will not fit and even with the modifications done your ski pressure would be horrendous.
Find yourself some HPG racing shocks on Ebay or in the swapmeet section.
