Leaf Spring Selection

I've noticed that F-toy builders seem to be running a front spring that is 1" taller than the rear spring. Other than the front obviously being taller, what does this do for performance?

Running say a 5" leaf spring in the front will net you close to the same as running a 4" leaf spring in the rear. It's all about weight. Most of the weight on the F-Toy is up front and very little is out back.

I suppose that's the answer that you were looking for?

he said why are people running 1" taller in rear, not in the front.

that is because our springs are inboarded and tucked up inside the frame and therefore losing "lift".

Actually he didn't: "seem to be running a front spring that is 1" taller than the rear"

You have me confused. I thought you had longer fronts. Please explain.

no the rears are longer than the fronts.


the rear springs are taller than the fronts cuz alot of the ftoy rear spring mounts are tucked up inside the frame instead of underneath, there for the rear springs dont raise the vehicle the same amount as the front.

I meant to say taller in the rear. If your rear springs are taller, then you're saying this is necessary for the inboarded rear springs even though the front of the rig is heavier? Explain...

Dude, you got it.

The front and rear are both far lighter than stock: The motor is 6-8" toward the rear depending on the builders preference... and the entire body is stripped off.

But the rear spring is mounted several inches higher on the chassis at its front end than it was when stock. So you need a taller spring in back.

I run a 5" AP spring in the front (minus the bottom leaf) and a AP 3" buggy super flex spring in the rear with a longer shackle. This has been the ideal setup for me. Works great.

I asked around and most are running either 5 inch or 3 inch springs in the front with the rear shorter an inch if they french the hangers or inboard the springs. I went with 3 inch springs all around (I'll inboard and run a longer shackle if I think I need to later on) and ordered mine from Trail Gear. The free shipping saved me the price of the front springs, cause I'm on the right coast, plus they have great customer service and have everything in stock and of course sponsor the ftoy series.
