Hi all, i have recently bought tough dog leaf suspension kit, and for some reason i got the ones designed for heavy loads and she is rough as guts on the road!

i want to remove a spring or two to make the road softer and get more flex so my question is: how many should i take out and which ones?

Also are there any difference to the other tough dog packs? Or do they just put extra leafs in?

Any advice would be much apreciated

Cheers Hayden

Picture of the pack to get an idea of thicknesses and lengths of the springs would be ideal.

Without that I would say to remove the third spring from the top and any overload springs that are in the rear.

Won't removing the load leaf from the rear increase axle wrap?

Ill have to post pictures tonight sometime after 5:30 i really apreciate the help!

Depends on how light the rest of the spring set is. Technically removing any leaf will increase axle wrap, you are lowering the strength and spring rate of the suspension therefore allowing more rotation.

I like to keep the smallest of the load leafs to help distribute the force and minimise wrap. But as stated once there are pictures you will get much more help.

Rear The other is front

[Zook_Fan]

Second from the bottom on the front, I'd take out the very bottom and second from the bottom in the rear set.

Note that removing leaves will reduce spring strength and consequently life depending on use.

[hayden1992]

So removing 2nd from the bottom in the front and the two bottom ones in the rear is what you suggest?

And this wont get axel wrap?

[Gwagensteve]

Yes, every leaf spring suffers from axle wrap. Axlewrap is a product of torque and traction. How much torque and traction you can deliver will dictate how severe it is. It shouldn't be severe enough to break yokes/kill unis in that configuration.

Okay cool cool, so what are the leafs that you suggest i take out are?

Like what are they called or what do they do? Do they have different tensile strenght or flexibility? Or are they all similar?

[Gwagensteve]

Zook fan's advice is sound, although I'd probably remove the bottom leaf and third from the bottom in the rear- this will leave a short load leaf.

The material is the same for all leaves in a pack. Shorter, thicker leaves are harder to bend than longer, thinner leaves. The idea with load leaves is they don't affect ride until the main leaves are nearly flat, then hey add lots of rate to prevent bottoming.

Those packs are far too stiff to work properly in a sierra even at GVM.
