Item Description
Offered Here are TWO (2)  Newly Made HO Slot Car Pick Up Shoe SPRINGS for the Aurora SUPER MAGNATRACTION style chassis. NEWLY MADE B.T.O. Better Than Original! Aurora Super MagnaTraction Pickup Shoe Springs: These springs are made in the USA from .007" beryllium copper.   There are 9.625 coils per spring at an uncompressed spring height of .200". Original Aurora G-Plus and Super MagnaTraction springs used an outside diameter of about .098" while the spring hole in the chassis measures about .112".  This gap of about .014" gives the spring too much leeway and could cause the shoes to tilt and not lay flat.  Increasing the O.D. to .105" allows for a much better fit and performance.  These springs are designed specifically to be used in the Aurora Aurora Super MagnaTraction style chassis which includes the Speed Shifters, Blazin' Brakes and Cat's Eye.  They can also be used in the Aurora G-Plus when a shorter, weaker spring is desired. Note: Aurora used the same pickup springs in both the G-Plus chassis and all the Super MagnaTraction style chassis.  Because of the different pickup shoe design between the G-Plus and Super MagnaTraction, the stock G-Plus springs can often be too strong for the Super MagnaTraction style chassis, resulting in rapid shoe wear and deslots.  This spring was made specifically to work better in the Super MagnaTraction style chassis. Note: Both the new G-Plus and new Super MagnaTraction spring use the same wire, number of coils, inside and outside diameter.  The only difference between the two springs is the uncompressed height.  The G-Plus is at .225" and the Super MagnaTraction is at .200".  The shorter free length of the Super MagnaTraction spring results in a weaker spring.
