hi all i was wandering around autozone today when i noticed after market suspension parts for light trucks that should theoretically work to replace the faulty airbag system with ease and low cost.
first is heavy duty rear shock springs. kit includes all mounting hardware. installs directly around the existing shock absorber and can lift 1250lbs for $19.99 for set of 2. (for obvious reasons these cannot be used with adjustable air shocks)
secondly they have heavy duty helper coil springs which also includes all mounting hardware this uses a u bolt to attach to your axle underneath the frame and can lift 1500lbs for $19.99 for set of 2.
finally once you have the springs installed simply use coil spring boosters to achieve desired ride height set includes 4 pieces for a max. 1in rise on each side for $3.99.
right now it is entirely speculation that this setup will work i will be purchasing and installing these parts (all 3) sometime in the next couple of weeks. if you try this or forsee a problem with this setup please let me know. i do not know the weight of the vehicle but together this should lift 2750lbs it also might work with just one or the other. and there is no need for welding or removing the old airbags. thanx for reading.
