it's a 1969 beetle in need to get it higher

Coil over shock absorbers will do it quickly, adjustably and cheaply. So will air suspension shock absorbers, but less comfortably.

Otherwise you will need to fit adjusters on the front torsion bars and learn how to adjust the rear torsion bars. The first is expensive and the second is infuriatingly fiddly.

higher how low is it now may just need new springs
