Rat Rod Suspension Choices....please Help

Guys and Gals i would like to get opinions on what front and rear suspension set ups would be good for my 38 Chevy Rat Rod Truck,i really like the traditional straight axle or drop axle in the front and i have a 9 inch for the rear but do i go ladder bar,4-link or old school single spring with shocks or coil overs? i know nothing about what front axle to buy or type of rear suspension is best for my aplication...as far as front suspension and steering set up i honestly know nothing about straight or drop axles or what steering components to use....i have looked at many photos and i do know i love the old school look but at the same time i would like to make an educated decision and go with a setup that works well,ride comfort is not a huge concern but i want it to function as it should with a reasonable ride.Any sugestions i would be greatfull and by the way please send me any links or photos that would be helpfull if you would like and just food for thought i will be building a custom frame and not using the stock 38 chevy truck frame.thanks again for any help.

Sub-frame the front with a late model GM clip. Power steering, disc brakes, anti-sway bar. CHEAP to do... Lotsa parts anywhere. Maintain the original truck frame from the engine compartment back. that way the body goes back on in the same mounting holes and eases reassembly...

For that matter subframe the rear also and really have a cool ride. Make it any ride height you wish.... Its all in the layout of the subs.

rat rods don't look good with a clip job, They look alot better with a drop axle.

For the front go to Speedway or one of the other guys like TCI and get a front axle kit..if yo get the painted kit it is reasonable in price and can be gotten with either 4 bar or hairpins..If you are into looks get the hairpins if you are into handling get the 4 bar..On the rear I like a 4 bar myself..Sometimes on the rear we will do what I call a V bar which is very similar to the old wishbone style with two bars from the outer ends of the rear axle and comes together with one large ball joint positioned directly under the forward u-joint.Requires a panhard to make work on most installations..

On springs if you are into handling use coil overs..the traditional "look" needs the transverse spring..

Myself if anything I err on the side of works and handles..Maybe irritates the "traditional crowd" but then they are not driving the car..

To get an idea look at what is being done on the sprint cars as those have to handle well..


Just another thought is that I think those old chev trucks used two leaf springs and you can get a spring setup like that from Speedway that I know of..Remember it is your car being built in your shop with the skills and resources you have available to you at the end of the day..

I have tried most all of it and now do what is known to work..
