why is that?The solid axle trucks have not been competitive for more than 10 years.
thanks for the info.You are looking for trucks that were built before Marty Reid started CORR think SODA the Short-Course Off-Road Drivers Association in the early 90's (yes I have been around that long).
i see no problem in building a VERY LOW COG car with a front solid axle. in fact, i've done it myself. the front axle does'nt necessarily sit under the frame, and when it sits infront of the frame, it can be made so the car's COG is as lower as in an IFS car, if not lower.Another factor is the center of gravity.
Think of a F1 car if you could move the center of gravity down 3 inches that would be a huge achievement. .
if you go 4x2 then you dispose of the diff and then we're talking two knuckles and one strong chromo connecting tube, which would be lighter then any IFS setup.....If you can save 50-75 pounds or more by running an aluminum center section and CV shafts in an IFS set up over the weight of a solid axle and lower the center of gravity 12 inches by lowering the ride height of the vehicle that is a HUGE advantage.
steering is no problem, since the steering devise can be mounted on the axle and not on the frame. this would completely solve any frame related bumpsteer, and other steering phenomena. besides, once you solved those steering issues, there's really no major factor to make you vote for IFS. otherwise, TTs would'nt run solid rear axles, and would run IRS, is'nt that so????[/QUOTE]Other considerations are the steering, adjustability, slip angle of the tires during cornering.
no. it would be much easier to build a strong front solid axle than to build a strong IFS, with the same unsprung weight.Another consideration is that these trucks are very wide and when you are at the point that you have to make a custom width front axle and reinforce it so it is durable it is not much more work to go to an A arm set up with CV shafts.
first of all, let me thank you for your elaborated posts - i really appreciate it.Do you have a specific problem or question with your build?
I looked at your posts with the Frog 2 are you working on that or something new?
i was thinking YES, with a little corerection - the solid axle(empty with no diff) will be located INFRONT and not UNDER the frame.Barry correct me if I am wrong.
You are building something new that is not the grass hopper.
The new vehicle will have-
rear wheel drive (solid axle)
long travel possibly radius arm front and four link rear suspension
you want a front that is not driven and not IFS
you want steering that will provide feel and not bumpsteer
If you read that and thought YES, I understand what you are after.
One big problem with a solid front axle in a desert racing application is what I call lack of "Recoil", but I dont know what other terms are used to describe it.
When a solid axle front end with long link suspension droops out, it moves back, when it hits the next bump, it moves foreward and tries to move up at the same time. This is not a good thing.
