Dropped spindles are simply spindle castings where the axle (or hub center) is moved up away from the lower ball joint. This lowers your car/truck/van by moving your wheel up in the fender well. There is a limit to how far you can move the axle up (you run out of casting), which is why you see most spindle applications drop about 2 inches. Precision and maintaining the correct factory alignment specifications are important when it comes to making dropped spindles.

One part of this project is remove the original 1958 split screen beam and replace it with a 6-inch narrowed and adjustable beam accompanied with 2.5-inch dropped disc break spindles from a 1971 Volkswagen bay window bus.

For this post, we will concentrate on converting the original bay spindles to 2.5-inch dropped spindles.  The result of this modification will drop the front of the bus down 2.5 inches, creating better road handling since the vehicle is at a lower center of gravity.   The beam can be also adjusted to even further lower the bus.

The arm is cut and the jig structure is unbolted and moved down 2.5 inches creating a gap which will be filled. All original factory geometry is maintained.

A piece of steel is cut to fill the 2.5-inch void. Steel is also beveled for maximum weld penetration. Steel is then heated to cherry red in preparation for TIG welding.

    Hi, I am from California, I would like to know if you make drop spindles for a 1971 vw Bus, if yes, and I send you mine, how much would you charge?

    Thanks a lot,
