My 4wd is IFS can I convert it?

IFS Conversion to beam axles, Why and how?

Okay you have a 4wd you love with IFS holding it back what to do? IFS is limited in its articulation to give the best road manners and stability, when you lift an IFS vehicle you change all the CV angles and the drive shaft's etc stay the same length. this is the major limitation you can only go so far and at that point you loose some downward travel or you may start increasing maintenance as the leverage increases on steering components.

You have five options:
Do nothing maybe fit a winch and drag it where you want to go.
Solid Axle Swap, put a solid axle from another 4wd into this vehicle.
Buy another 4wd, invest in the radio gear etc and keep this as it is.
Buy another 4wd, get all new gear and sell what you have.
Buy another 4wd, swap all the accessories across and sell what you have.

Okay you are thinking Solid axle swap, nice.

Do your homework measure the width of your rear axle and find something suitable, call into the workshop and discuss the options, see what others have done, go to 4WD events and see how it performs, look at the whole price you have brake lines, brake booster (bigger brakes), drive shafts, transfer cases and a whole raft of other things to work out too! Anything is possible but with a little thought some things are definably easier!

To link and use coils or use Leaf Springs?

A link suspension uses links to locate the axle from moving side to side and front to back, while allowing it to travel up and down and articulate. We must agree with the current majority that a link suspension with coils, coilovers, quarter-elliptics, or air springs is definitely cool, and that is the most common argument for building your own setup. The problem arises when you think you know what you are doing and just start putting bars and links under your truck. Just because you saw it on some race truck or rockcrawler doesn't mean you need it for your weekend wheeler, though we have no problem with building one just because you want to try it.

There are some definite benefits to running a link suspension, but to do it right takes time, money, and some more time and money. First, the pros and cons of building one. The choice is yours, but please consider everything before you get started.The fact remains that a well designed and tested four-link will provide a superior translation of power to the ground and far higher ride quality in most conditions than a leaf-sprung suspension. The secret is really in the testing portion. If you build link's on your rig then be prepared to fine-tune it.


The biggest question with building a link's is how long should the links be and where should they attach to the frame and axle. This alone will determine how the axle pushes the vehicle, if the rear of the vehicle lifts or squats under acceleration, if wheel articulation causes the rear axle to pivot and steer, and how the body rolls in turns and over obstacles. The desired amount the vehicle does each of these things is different depending on what the vehicle is designed to do (go fast, corner, crawl, articulate) and how the driver desires the vehicle to respond on different terrain. There is no one right way to build a four-link the same as there is no one perfect off-road vehicle, but it can be tuned to do certain things better than others, come see us and we can help engineer it.

For most truck owners an all-around four-link (front with panhard or triangulated) is the desire, but that will not necessarily be the best rockcrawler, desert jumper, and mud bogger suspension. In addition to all the geometry of designing a four-link there is also the problem of what will actually fit on the vehicle you are building. Will the frame support the links where you want them? Will the fuel tank, exhaust, crossmembers, and driveshafts all fit with the links and allow for proper articulation? Unless you are building a truck or buggy around the suspension. If you are starting to like the idea of keeping the leaf-spring suspension, we don't blame you.

The benefits

The benefits of a four-link over a simple leaf-spring suspension include controlling axlewrap, better departure angles, controlling axle path, and reducing the uncontrolled variables of axle movement down to just spring rate and shock valving. In addition, a four-link can also allow for more travel and articulation that can provide more traction, though we feel that too much of both can cause problems. Weight is also a concern of the modern-day wheeler since excessive weight eats power. Though a coil spring is lighter than a leaf spring, when you consider the weight of the links and mounts and everything else, the gains in weight are minimal.

The major benefit of a leaf-spring suspension over a four-link is cost and maintenance. It will take more time and money to remove leaf springs and design, build, test, and rebuild your four-link than it would to just put on a good leaf suspension. Plus we have setup some very impressive leaf-sprung suspensions that allow plenty of travel and articulation.
