ifs vs dropped axle

Hello all, I am new here and would appreciate some feedback. I have been unable to decide whether to install an ifs or drop axle in my project. I am building a fenderless 31 model a truck. i want a tasteful mix of traditional and modern. I love the look of the drop axles but want the performance of an ifs. I have designed a independant dropped axle design that I am considering fabricating. Any suggestions? I will only use the ifs if it looks clean, nothing frame wise showing. has anyone built a drop axle that could hang in there with an ifs? Thank you

Some may disagree but here's my cut at it......

Traditional: Dropped "I" beam with split bones or hairpins.

Semi Traditional: Dropped "I" beam with four link.

Street Rod non traditional: IFS

All that said, unless you're going to be thrashing around road courses its hard to beat a dropped "I" beam with a four link. Its a nice compromise between traditional and modern but still has the overall look of an "I" beam installation.

ifs vs drop axle

thank you centerline, i couldnt agree more. I prefer the i beam and bones over anything. But, Id like the capability of cornering if my right foot warrants it. not that it would be that often. i dont know what to do. Looks or function. Thanks

I agree with Centerline on this one.

Do you want to look cool or drive it like a getaway car ?

Fenderless = traditional w/beam axle

Fendered = either way, Mine is w/IFS but is fully fendered and in my part of the country, not a bad idea.

If you are in fact doing a truck, I suggest you do some Photoshop work to make sure it's 'right' w/o fenders as many leave a lot IMHO, to be desired

While this is a 1932 Ford DEUCE pickup
The lines are similar enough to envision what a Model A pickup could look like.



NOTICE the drilled I-Beam axle

IMHO a split wishbone looks the best on a non fendered vehicle but the 4 bar most definitely RIDES and HANDLES better. Some concessions sometimes have to be made ... for ease of parts availability and getting the vehicle up and done.

For a truely " tradional " Model A ... you would need bias ply tires, a 6volt system and a generator. On my 32's ... I use a 4 bar front suspension, a 12 Volt alternator and radial tires. Tradition be damned ...

I agree with the "child". If no fenders dropped, fenders either way. I have had a 40 ford with a dropped axle, and I have a 33 and 46 full fender-ed both with Mustang II, the 40 had a 4" dropped axle, rode good, the 46 maybe rides a hair better, corners better than the 40.

drop axle vs ifs

thank you for the responses. I totally agree the drop axle is the right look. I just like the challenge of having the best of both worlds. Its hard enough pulling off a fenderless truck correctly to begin with. What do you guys think about my independant drop axle design I came up with? Is it worth it?

What does it look like and is it safe, guys have used twin I beams, but I have no idea how they worked for them. The frame Deuce showed looks good to me. Your not going road racing. Ifs on a fender less car looks bad IMO.

For what it's worth, there is this alternative.

Traditional look...



But it is IFS...(Ford Twin I-Beam).



And here are twin beams on an open wheel car.





Twin beams are best suited to hand fabricated frames but they can be adapted to exisitng frames as well. The first photo above uses a Ford Econoline frame with the front rails massaged to accommodate the twin beams.

For more info and pics on using twin beams you can click here.

drop vs ifs

i love the feedback, thank you. most likely I will run a drop axle for the look. Its hard to beat. i will attach my ifs drop axle design as soon as I figure out how to. Im not to crazy about the twin I-beam. Did I mention this truck is on a duece frame? i think they look nice, especially open wheel. ill get some pictures up as soon as I have anything worth showing. Thanks again

There is another mmeber here that built a split tube axle which gives you the flexability (almost) of an IRS but the look of a solid axle.



Here's his website with a lot more pictures:
