Are you jacking your prowler up to get pressure off of shock?If so dont be afraid to slip a piece of pipe or tubing over your spanner wrench for a little help.Also cheap spring compressor is hose clamps.You might need to use 4-6-8 clamps.Just spread them around the spring and skip a coil if your clamps are big enough.Tighten them evenly and you should be able to reassemble your stock shock.
