Rear suspension set up

[redws6rocket]

What are you guys running for rear suspension in your pullers? Why is it some trucks look lowered in the rear, a lot of the Danville trucks look like that and some have the back way in the air? Is there any advantage to either one? Thanks guys, looking forward to this year!!

I only have dhd adjustable blocks on mine. But with 1500lbs of weight on the front it has that same look you are talking about. I prolly could put some heavy duty shocks on the front to hold the front end up more since i still have oem shocks on it.

People have different theories as to what angle is the best for hooking at. With a 2.6 block it solid then you don't have to worry about losing any hitch height or rear suspension for that matter. Keep the rear tires aired up good also again that will reduce the possibility of loosing hitch height.

Like Darrek Leis's truck how it sets so low in the rear, my guess is for his hitch setup

The rear wants to squat and the front wants to lift. If you can minimize how much either/both move in those directions the better. By properly positioning the chassis low in the rear and high in the front to start, movement can be minimized...

Hitch and chassis play a big role. If you look, most of the gasser guys have moved away from the rears jacked up in the air and gone to the "dragging ass" stance.....they've learned something over the years.

Also pay attention to chassis/body angles, I've seen truck bodies mounted on the chassis so that they appear to be running differently than they are (ie. the rear of the truck is 8" off the top of the frame, but the front is 2"). The truck "looks" level, when in fact the chassis is not (although I haven't seen it much in the diesel world yet).

On a stock/street truck, you are kinda limited as to what you can do.

Our best setup by far was 3" lowering shackles in the rear, blocked and the front torsion bars completely lowered but sitting with CVs level on stops.

so being low in the back with the hitch point moved up and blocked and weights in the front is being favored over the lifted rear? I know my truck is lifted 3" in the rear so I can get 26"s.
can we see some hitch setups on lowered trucks?

Don't raise the rear of the truck up to get hitch height. Get a hitch that will adjust. If the truck runs a receiver style hitch then there is a general rule of thumb to follow to make it hook well. If the rear of the truck goes up, raise the front. If the front of the truck is low, lower the rear. Good luck and have fun.:thumb:

I'm gonna get me some shackles to lower if down some and get a gd adjustable hitch. I bent a couple last yr.

Having the hitch in close to the body is also something to keep in mind. The further back the hitch is, the more leverage it will have to lift the front end. I don;t pull much but I decided to get a rollpan and BigChevyHitch hidden receiver. I don't have his hitch yet(since I'm not sure if my old one will fit yet) but it is designed to tuck in very close to the roll pan.

What if your not running a reese style. Instead running a drawbar style and you need the rear up to increase the angle of the hitch to where it should be?

Any one have photos of stops in the front?

 

[bubba2400]

I have some photos of front stops in my garage.

If the truck has a true drawbar you can get away with some different chassis angles but I prefer to setup the chassis almost the same way. Front comes up some along with the back to a point. But if you nail the drawbar angle perfectly you can make the front lower than the front and not lift it too much. Hard to explain I guess. Sometimes takes a little playing around with it to make it all work together.

The other way to get the angle correct on the drawbar is to move the attachment point back on the frame. And depending on how the drawbar is made if the drawbar is supported off the rear of the frame then it will mostly be a waste of weight to install.
