Ok Im going with coil spring fronts and coilover rears. What spring rates?
Stats: 52' Chevy 3100 with 5.3ls 4l80E trans. 3:23 chevy 10 bolt
My plan was to originally go with air ride. After much deliberation I decided to just go with Coil Springs in the front and Coilovers in the rear. I am building a daily driver so I am needing help with what spring rates I should go with. Thanks for the help in advance. |

I cant remember what the rear were but I have 450lb coilovers for the front.....LS3 and tr6060....the rears will also depend on if you have a rear fuel tank.but are less than the fronts......would be best to call whoever's your gonna use and let them recommend what you need..

Re: Ok Im going with coil spring fronts and coilover rears. What spring rates?
If I remember correctly, you're using a standard MII setup.
There's been a number of discussions about it here and elsewhere. It seems the MII 4 cylinder are what most use for optimum comfort with an AD truck. http://67-72chevytrucks.com/vboard/s...d.php?t=554035 http://67-72chevytrucks.com/vboard/s...d.php?t=438015 Some of it depends on where you're going to mount your tank, what engine, AC, etc... I see you're using an LS, which is lighter than a small block, but the 4L80 is pretty beefy. I just recently finish the IFS install on my truck. Since I have a 3600 truck and I'm eventually going to add AC, I'm planning on using the 6 cylinder or even station wagon style springs for mine. I would rather have a slightly stiff ride than mushy handling. Eaton Detroit has a good guide for MII springs. They have more selection than you know what to do with. https://www.eatondetroitspring.com/o...-coil-springs/ As far as coilovers, can't help you there. |

Tech at Speedway suggested 210# coilovers on the back. I have a 22 gallon, rear mounted tank. S10 chassis.
Haven't driven it yet... |

I think you need to determine corner weights in order to minimize the trial and error method that will ensue.

What's your front suspension - MII?
I used 350 lb fronts and 300 lb rears, but since mine is a panel truck that rear rating may be irrelevant for you. I applaud your decision to go bagless. As a former "lay frame" guy myself, I decided on this build to eschew any unnecessary accessories or gimmicks and keep it all old school simple.

You might check with Rob at No Limit on them as they do coil overs on a lot of their chassis. http://nolimit.net/
