im looking to lift my 89 k1500 6"
im really not looking to lift the rear with blocks, i'd like to lift it with lifted leaf springs, can anyone tell me where/how to get them
i cant find them anywhere online

Superlifts got some pretty nice all spring kits for straight axle trucks. Another thing you can do is to replace the rear hanging shackles with Off Road Designs flip kit, You'll get 4" of lift with out changing the rear springs or putting blocks on & it will also align your driveshaft for better pinion angle.
