i have an 83 gmc k1500 and i was wondering if its possible to flip the leafsprings upside down to make it higher i know they do it on campers and stuff so i was wondering if it would work on a truck also

You can do it but the springs will break easier if you do any offroading.

99 Silverado40 is right. I did it on an old F-250 farm truck I had. I wanted a cheap lift and thought it would work. After about a month of driving on the farm (it was just a truck drivin strictly on the farm) the passenger side snapped like a tooth pick. It will not take kindly to servere bumps and especially towing a hay wagon thats loaded as when they broke the hay wagon spilled. (That was real fun let me tell ya picking up everybail - and youknow how farmers load trailers - all over again). Just my 2 cents.
