4-link info


Well-Known Member
Does anyone know where I can find some info about building a 4-link? In particular I am looking for info about trailing-arm/top-link mounting locations under the cab and shock location on the trailing arm (ratio differences). I know there is a lot of trial and error out there but is there any real info? Kritter said something about a book by someone. What else is out there?

There was a Discussion on lower links a while back that has tons of info in it, try searching for lower links 101, as for upper links maybe its time for upper links 101 I know I could use it. How about guys.

The book is Chassis Engineering by Herb Adams http://www.amazon.com/exec/obidos/redirect-to-external-url/002-4158553-3756855?path=http%3A//s1.amazon.com/exec/varzea/ts/exchange-glance/Y03Y1844797Y6826608/qid%3D1053497135/sr%3D1-2, road car stuff but good concepts along with diagrams and some math to help you out, a very good reference book. The Lower llinks 101 http://www.race-dezert.com/ubbthreads/showflat.php?Cat=&Board=shop&Number=37729&fpart=&PHPSESSID= is a must read also, there are many far more knowlegable people than I who contibuted a lot of good information to the thread. The end result is there are no easy answers as to placement and I spent 4 or 5 hours working with autocad and then had someone who was a lot better at cad than I work even more hours to get me our mounting points that I believe are very good. Its not a project to be taken lightly and will require a fair amount of research. Good Luck, Curt

What type of vehicle?

Give Nestor a call @ Newline.
He can point you in the right direction.

its a very rewarding but difficult project. Make sure you do your research first, and ask any questions on the board, people on here are so helpful.

Also dont second guess yourself, i did that and am now pissed. keep the IC where your drawings put it, not where it might look like it would work better...

sure my shop is in mesa at the end of the 202 if you dont mind coming for a drive. The 4link is nothing phenomenal but youre welcome to take a look. It still needs a bit more work but most of the stuff is done. We have a few ls1 powered sand cars in the shop if youre into that sort of thing. Also we have a bunch of turbo crap at the shop not sure if youre into import cars.

I am not in az right now, but i have all my employees there almost 24/7 so youre welcome to stop by.
