Proper bushing alignment is an example of a "little thing" which when combined with other "little things" can make a big difference in how well your car performs. There is exactly one way for bushings to be properly aligned as described in the Bushing Alignment how-to video. Conversely, there are an infinite number of ways they can be misaligned so the odds are really stacked against us. Bushings which are not aligned properly result in unwanted friction in the rear drive train.  This may seem trivial but can reduce rear wheel RPM's noticeably when compared to a car with properly aligned bushings.  While it is virtually impossible to align bushings "perfectly", using the components in these kits will get them very, very close (much closer than just using an axle) and just as importantly, it will ensure consistent, repeatable results.

Bushing alignment kits are available for bronze bushings from three (3) manufacturers:  Slot Car Corner (SCC), Slot.it and Ninco (2.5mm).  Kits include a pin gage sized specifically for a given manufacturer's bronze bushings along with a 3/16" burr bit to enlarge chassis bushing carriers slightly (refer to the video for more information).  The SCC bushing alignment kit also includes a pair of SCC racing bushings which are counter-bored for less friction.

Individual components in the kits (pin gages and burr bits) are also available for purchase separately.  Click the product picture (link) at the bottom of this page for more information.

Note:  These kits will NOT work with Ninco ball bearings.
