Hello, My name isXXXXX will do my best to assist you. I am working with your question now and will return shortly
hello im eric. do you need any other information
The specifications for the 1500, 2wd, 5.3 are 8200lbs max tow weight. the leaf springs will help with the etra tongue weight but dont add to helping the overall towing weight as the engine/trans setup can only handle a certain limit. I would say you are safe up to the 8500 +/- range if? you are not doing real long hauls up steep mountains. flatter roads are much easier
would it also lower the towing weight with high milage i am pushing 230000 on mine
Good question . It only lowers your max limit if? the trans is weak. If you feel the truck is solid, no trans problems, then to help is to flush trans, add Lucas trans additive and maybe optional external trans cooler. Flat rodas, older engine, drive easy and should be ok at the 82oo. if you have trans concerns, then that limit should be dropped some. hard to say to what
thank you very much.
