Another advantage to properly selected lift springs is stability - the center of gravity on a lifted vehicle is higher, and in most cases a higher center of gravity causes increased roll - stiffer springs can reduce this roll, lift blocks will not.Does anyone have any opinions on the benefits/ problems of merely using strut and spring block lifters as opposed to totally new springs and shockers. Big difference in out lay. I have no experience in lifting so would welcome knowledgeable input. Reading this thread it appears to be consensus that 40mm is max that won't cause CV problems.
Please note that properly selected - a vehicle can be lifted by fitting longer springs or stiffer springs - many people have "cobbled" together vehicle lifts by visiting the nearest junk yard and hunting down springs that visually appear to be suitable candidates and then trying them, no math involved and no knowledge of the original or new spring rates.
