Re: Make it handle
OK class, todays topic, rear locators. I chose my words carefully. Diagonal locators, Panhard rods, Watts link, wishbone,...... there are many. More than one way to skin a cat. for street performers, I like a panhard rod. I know, many favor other types. I have two reasons. 1. K.I.S.S. - keep it simple stupid! - fewer moving parts, easy to set up correctly. 2. Panhard rods allow you to set the rear roll center, and adjust it easily, without a complicated formula. While we may think (dream) about a high roll center with a low center of gravity, we are playing with trucks, not corvettes. High roll centers on the back of a truck will help keep it flat, it will also keep it spinning around.

Re: Make it handle
Can you briefly explain what you mean by rear roll center? feel dumb for asking but I just want to make sure I understand what you are saying here

Re: Make it handle
Don't 'feel' dumb for not knowing; it's a good question.

Re: Make it handle
Excellent description for explaining the difference RC & CG can play on a truck vs. a car. I hope to see your rig go round & round @ GG's Ft.Worth.

Re: Make it handle
C-10 ...... No, you should not need to make anychanges. Combination of that billet brackets and panhard bar length ought to be optimized for that truck. Easiest way to tell... is the rear axle centered under the truck at ride height? If it is .... leave it alone

Re: Make it handle
I'm sure it's been said before .... but I will say again ..It is because of people like you Rob and Tony also that I keep coming back to this websight . Thank you for putting in the time and explaining this so WE can understand it . This subject is something that has always intrigued me ... And will be useful knowledge when building my truck and will relate to my camaro build also.

Re: Make it handle
Here's where I'm at. I want a truck I can drive to a show a 1000 miles away and I want it to be able to do half decent in a slalom when I get there. I have a car with ride height adjustable coilovers on all 4 corners that corners like its on rails but truth is on the street its not that nice cause it rides kinda hard. My truck is a shortbox 65 Chev stepper.
Questions I have: 1. For a streetable setup that won't float your teeth what is a realistic goal for G's, .8 or .9 or??? 2. Is the rear trailing arm setup of the stock 65 worth trying to work with? 3. Same question for the front end. Should I spend the $$ on a full IFS 4. What would be a realistic budget for making the trailing arm set up work and/or what would be a better option for maybe a little more $$$? Just say as a number I had $4000.00 to spend on the suspension could it be done? Thx M5 |

Re: Make it handle
Thanks guys, glad to help. M5 - I'm thinkin about your question.
One more vocabulary word for today : Radial Deflection. ?? OK , Radial - used here to describe a type of motion. In a radius, around a fixed point. Deflection - when something is "deflected" it has changed it's desired path of motion. We want the rear axle to move straight up and down (no side movement) So, we want minimal "radial deflection" -the rear axle being deflected sideways due to the radial arc motion of the panhard rod. lost yet? OK, take a yardstick and lay it on the ground. Mark each end, carefully lift one end up 6" off the ground, and put a mark on the ground directly under the raised end. The two end marks will have gotten a little closer together. (about 1/16"). Now, repeat this with a 12" ruler. The arc that the ruler travels on is much smaller, and the two end marks will have moved much closer to one another. (about 2") When discussing "radial Deflection" you must know how much travel there is, to compare. The rule is, the longer the bar (radius) the less deflection (side movement) Rear Roll Center. - the height of this can be calculated by getting the average hieght of the chassis mount and the axle mount, as the truck is setting at ride hieght. Watch the Nascar teams, when you see the guy drop an extension down into the back of the car, and turn it around once or twice, they are changing the roll center. The chassis side mount on these cars is on a slide, and can easily be screwed up or down to tune the car. Todays homework, - What is your Rear Roll Center? Tony, did you mean Blue Moons? ![]() |

Re: Make it handle
We are at 455 so. D street. corner of D and Mill.
Blindman, how about putting up some picts? let me know when its up and running and i walk you through some set up and tunning. It would be good for the forum too. If you can, get some wieghts on it once its running. Find a truck scale, get a total wieght, then roll the truck back so that only the fronts are no, and get a front #. What Tires are you getting? |

Re: Make it handle
Looks great, Yes, you could move the mount up. But. it would end up going through the wood floor, right now it has about 3/8" clearance. If its not low enough when your done, we can swap you for a 4" stroke shock, and a 10" spring. That set up has a ride hieght of 12 1/4", compared to the 14 1/2" RH of the 5" stroke shock. It will drop the rear another 2', but I would wait until you have it all together to decide.
