Item Description
|
Offered Here are TWELVE (12) Newly Made HO Slot Car Pick Up Shoe SPRINGS for the Aurora SUPER MAGNATRACTION style chassis. NEWLY MADE B.T.O. Better Than Original!
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.
