They are purchased individually. They include one supplement, six longer bolts with the same hardness as the originals, and six AET washers like the originals. This is for all of us who lift vans, whether or not they have a Syncro. As you know, many problems arise when lifting a van: shock absorbers, CV joints, inertia, stability, braking... some are easy to solve, while others are difficult and costly. It's quite common, when lifting a van, for a driveshaft to fail over time. Why? Well, for several reasons: - The first is that it no longer operates at its usual angle, but rather we force it to operate at a wider angle, closer to the limit, so on curves, roundabouts, potholes... the CV joint can bottom out and "eat" the ball raceways. Unfortunately, the only way to change the operating angle is to install new CV joints. The standard T3 and 14" Syncro wheels have a working angle of 17º. The only way to increase it would be to fit the Porsche 924-944 wheels, which are equivalent and also have a 22º angle... although it's a bit of an expensive solution. The second reason is that when we lift them, we stretch the axle shafts. If you've ever had a CV joint nearby, you'll have seen that they move in and out. This is to absorb the up and down movements of the wheel. What happens? If we lift the van, we shorten the travel, and when the wheel comes down, it hits the stop immediately... We solve all this with CV joint shims.
