Load Leveling Shocks?

Anybody ever try the Load Leveling Shocks for the rear of a Duster. The ones with the coil springs. Is there enough room to install them or do they interfere with the edge of the gas tank?

Bad idea... They were popular here in Australia in the 1970's for people towing caravans. Shock absorbers are designed to damp the action of the spring packs against rebounding. All 'Load Levellers" do is transfer the sprung load from the springs (which are designed to support the load) to some other part of the car (shock absorber mounts) which is not designed to support the load. Can end up punching a hole through the floor of your car...
