Re: Suspension 101
If you haven't gotten to this chapter yet, Hot Rod mag did a nice write up on adjustable shocks. Obviously they said that dbl adj were ideal. I plan to run dbl adj coilovers front and back.

I believe the dbl adj shocks could benefit someone running slower then 10 sec. cars, especailly trucks. With any vehicle that has close to 60% of it's weight on the front, weight transfer is critical. That is of course if you use it for more then just drag racing.

Re: Suspension 101
How do they work for you? What shocks are you running? Do the rebound and bounce adjust the same?

Re: Suspension 101
I run the longer Qa1 coilover shocks. They adjust rebound and compression at the same time.

Re: Suspension 101
Yes I know it adjust the rebound and compression at the same time. I guess what I ment was that it adjust the comp and rebound the same percent. It's not like its a tyipcal drag shock, 90/10, 50/50, ect.

Re: Suspension 101
Right now it looks like I won't be needing the drag springs after all. I finished up assembling the bed (for years the bed floor wasn't attached to the sides) which really stiffened up the truck (along with polyurethane body mounts) and put on a set of Firestone Indy 500's and found out their reputation for stickiness is well deserved. I'm able to launch from a dead stop without tire spin for the first time in Old Yeller's history and that's with an additional 150-200hp at peak output.

Re: Suspension 101
I run single adjustable in the front. The old front shocks were QA1 stocker stars, that bolted in the stock location. Excellent choice, because compression is set full stiff, rebound is the only thing you adjust. However, if you run QA1 coil-overs, they adjust rebound and compression the same amount on the single adjustable. This is what I will be running with the new front suspension. I have never had a problem tuning the front
suspension on any other car with single adjustable. I tried the single adjustable on the rear, it was not a good choice. There are times when you need more compression to hold the tire to the track, so it won't attempt to bounce and unload. I ran M/T drag radials, so they required a good amount of adjustability to work. I would not run anything less than double adjustables on the rear. These trucks operate much like a ladder bar in that they hit the tire very hard. You have to be able to control the spring with dampening, as well as the added factor of the tires resitance to be controlled. Hope this helps. |

Re: Suspension 101
in this statment above what #'s do you use to divide the wheel base (If you have 60% in the front and 40% in the back, then take your wheel base and divide it by that amount. 100” wheel base would put you at 40” from the front axle. The height is a little more difficult.) this thread really has my attention. I was up most of the night in the shop with a copy of this trying to lay it out on the shop floor. I'm getting ready to do some front end work to my truck in the next few weeks and figured i would go ahead and do the drop spindles and custome springs you were discussing. also when i take the truck to be scaled should i manually lock the suspesion a ride level i want to get correct springs. does qa1 make a stocker adjustible for the 71 c10's. Can't wait for the rest of your chapters, i believe i can really start killing the mustangs now with this info, everybody in my county thinks I'm crazy for trying to race this big heavy truck but i like it.

Re: Suspension 101
Thanks Super 73 for this post. I've been trying to search the internet on things I need to do to get this old beast ('69 SWB) to hook up. djracer put me onto you/this post. I'm new to the forum, and just got my truck about 7mo ago. Having someone help you out like this helps alot when you're trying to build a semi pro street truck on a soldier's budget! Thanks alot!

Re: Suspension 101
All you need is some Beer and BBQ to make these old trucks run good. Ok here is what I ran on my 65.
-Moroso chevelle front drag springs -Comp. Engineering 3 way adj. shocks on the front -Stock rear arms with Rancho shocks -lowered the front of the rear arms 3" with 3 deg. positive pinion angle The truck weight was 3065lbs without me in it. I had a 468cid, PG, NOS Big shot plate and the truck ran 5.90s @ 112 mph with 1.29 60' I then sent the truck off to have ladder bars and coil overs installed. $2,500later it picked up 2 dimes. For what we are doing, all of the checking corner weight, preload on whatever side, instant center, and all of the other b.s. leave that to the prostock guys who are looking for every .001 |

Re: Suspension 101
Nice 65. Black looks good on these trucks. I lowered the front of the trailing arms to get rid of anti squat. I used square tubing and welded two pieces in the verticle position on the lower part of the crossmember. I gusseted the tubing, ground off the factory rivets on the trailing arm mounts and moved them down 3". It got rid of the anti squat problem and lifted the front more. Oh I almost forgot the another reason the truck would leave with the wheels up is that the engine was moved back 11". If you would like some more info PM me and I would be glade to give you some more info like what shocks,springs ect.

Re: Suspension 101
Nice truck! Depends on the engine you are running. The moroso drag springs for the 70 chevelle will work fine. If you have a SB, run a SB spring and the same for a BB. I would keep the stock rear springs. If you do not mind me asking, what size rear wheel and tire are you running? I am building a 72 swb and I like how your truck looks.
