    The increased articulation of a solid axle swap kit that sits in a hardened casing of steel between the wheels is going to mean a lot less breakage during rock crawling and other bruising off-road cruises. It will also mean it's easier to modify your rig with a lift kit. But remember that during grocery store trips your derriere will feel every pothole on the flat road and steering at higher speeds will be more challenging without sway bars, steering stabilizers and all the other bells and whistles of ride smoothness that accompany an independent axle. 4 Wheel Parts carries solid axle swap kits for a variety of applications with lift heights up to 6.99 inches from the very best off-road accessory brands like Poison Spyder, Off Road Unlimited and G2 Axle & Gear.

    Converting to a solid axle can improve the articulation and resilience of the suspension on a Jeep or any other off-roading vehicle. 4WheelParts sells all of the parts you need in a solid axle conversion kit designed to fit your vehicle make and model. Choose the Poison Spyder Full Width Axle Conversion Kit or the Independent Front Suspension Eliminator and Solid Axle Swap kits from Trail Gear. These kits contain brackets and may also include a shackle reversal for extra lift.

    Pick the Right Kit

    Make sure that the kit you choose is compatible with the make and model of your rig. To find Dodge Ram 1500 solid axle conversion kits or kits that fit other trucks or Jeeps, enter the vehicle year, make, model and submodel. Some kits also specify lift spring perch measurements or require the use of spacers.

    All the Parts You Need

    The Trail Gear SAS kit makes it possible to replace an IFS suspension with a solid axle. The IFS Eliminator Kit contains a front differential armor plate and gusset wheel bearing for the upper axle, as well as knuckle service kits. Depending on the kit you choose, additional parts or components may be necessary to successfully complete a conversion. You might also want to consider Jeep lift kits or rear lift kits for other makes and models.

    Make the Switch

    You should be aware of the advantages and disadvantages that come with replacing the IFS on a Jeep or truck with a solid axle. The resiliency of a solid axle is unbeatable when crawling rocks and navigating extreme terrain. Fewer on the fly repairs are likely to be necessary on or off of the trail after this conversion.

    If you still plan to drive on streets and highways, a solid axle may sacrifice ride quality. You might consider modifying the IFS with ball joint spacers, a dropped differential and sway bar and upgraded shocks. You can also install a long travel kit for front axles. All of these options can improve articulation and strengthen your suspension for off-roading. 4WheelParts has the lowest solid axle swap kit prices backed by a 90-day Price Match Guarantee.
