Prothane Polyurethane Universal Dust Boots
Many of you are finding out that the rubber boot on your ball joint or tie rod has rotted away or has split. These boots are extremely important for the suspension of your vehicle. Fortunately, Prothane makes Universal Dust boots that will fit most vehicles. These dust boots are made of polyurethane and are far more durable than rubber. This will seal your boot to retain the grease in the joint, as well as protecting the joint from dirt, sand, water and snow.
How-to obtain measurements
In order to select the proper boot, you will first need to grab a few measurements. The best way to do this is with a set of digital calipers. You will need to measure the diameter of the base where the boot will sit, the diameter of the shaft (also called the Pin Opening Diameter) and the height of the boot. Once you have gotten to your tie rod end measure these three spots. Be sure to be as exact as possible and to write down your measurements. If you have any trouble getting these measurements, give our customer service team at DST a call. It is important to note that you do not want to choose a boot that is bigger than your measurements. You want to choose a boot that is just slightly smaller than the measurements you obtained. The elasticity of the polyurethane will allow the hole to stretch and grip the joint tightly. If you choose a boot that is too large there will be a gap which lets in debris.
After Measureing Your Dust Boots
Now that you have these measurements, you can verify that this is the boot that you need. If you find that your measurements do not match this boot, go to our Universal Dust Boot page to match a part to your measurements.
