Hello Tater06, Measure from the outside of each bushing flange on the rear axle to determine which length tube you need....eg. the current NSR triangular sidewinder pods are 31mm across from the outside of each bushing flange,...so,....the 31mm size is the one you need for these pods. 


 The SlotingPlus axle tubes were released 15+ years ago for use with the Ninco Anglewinder chassis cars, which were very flimsy in the rear axle upright/ motor box area, resulting in "Ninco Hop"...........these tubes are a godsend for any anglewinder/sidewinder application, but, be aware that for many sidewinder applications, the tubes must be "notched" to clear the rear axle.


I have used them on tons of my own and shop customer cars, and recommend them highly, particularly for quicker/smoother wood tracks where the lateral loads are much higher than on plastic (unless you run with magnets on plastic).

On cars with a steeper motor angle (this is a Ninco Ferrari), the tube can be installed as is.....



On sidewinders, the tube may well need to be "notched" to clear the axle.
