Can I double the shocks in front and rear to help payload? Or what are they suppose to do? The truck is 1988 Chevy K1500 4x4 with 70500 miles on it. The engine is a 350.
nope. shocks provide damping, they do not hold the vehicle up. springs hold the vehicle up, and you can add leafs, or supplemental springs/airbags/airshocks to up your payload. only the rear springs will help your payload, and most basic modifications you do will make your ride harsh. what exactly are you trying to do? tow a heavier trailer? level the ride out with a 4 wheeler in the back? carry more shingles? examples will give a better idea of how to beef up your truck for more weight.
Yep, add payload by air bags or other overload systems depending on your needs and use pattern. However, shocks can help stability with a load as can sway bars and the like. Again, depending on your needs.
Well I use it to pull steel, trailer houses, dually trucks, concrete, or the term is around 6 to 20 tons. It only has 5 ton springs. I took a pair of a ton truck springs out of a junkyard and put it on the half ton truck. The brakes are 14 in diameter. shoes are about 4 inches. wheels are 16 inch steel wheels with 10 ply tires. How can I add more leaves without taking up too much space. Need to have wheel travel.
5 ton or 1 ton truck springs? I can see pulling 12k behind a 1/2 ton truck, but I'd hope to never cross paths with you pulling 40k behind it. In most states you'd be hard pressed to pull 26k behind a fully outfitted 1 ton diesel legally. anyhow, some add a leaf and load levelling systems go on top of the spring pack and don't interfere with the rest of the suspension until you reach a set weight. You won't be adding a whole spring pack next to the exisitng ones. By adding leaves to your spring packs you'll definitely increase your payload capacity and in turn lose wheel travel and flex.
I would go with the firestone ride rites. I love mine and they helped alot. Made the ride alot smoother when loaded. I also doesn't make the ride any worse as it would by adding leaf springs.
