My truck bottoms out on bumps, and rides badly?

some of these s10 s have fiberglass springs have a look see if the are cracked or broken

You better head to the Mechanics to check for the suspension system of your vehicle. It may be due to the worn off of the springs, but also may be due to problems of the ball joints or the torsion bars.

I would say if you want to keep it stock go to lmctruck.com and look for stock replacement springs for your s-10 and invest in some good shocks like some bilestine or edelbrock. They may cost more but in the end they last way longer. Oh yea and get new brakes b 4 your old ones wear out and you end up getting into a crash. Also have your local alignment shop check your steering for the same reason. Keep general maintenence on your truck and it will last for almost ever cause my chevy k-2500 (1989) has lasted me almost 20 years just by doing that and I'm the first owner! I hope this has helped ya and I hope your truck will ride smoother after you get new springs

Ya so ?? sounds like you need some Shocks + maybe some new front end parts. Make sure your springs in the back are not broke . Replace the shocks with some new ones about 20$ each.
