2 Newly Made HO Slot Car Aurora G+ G-PLUS style Pick Up Shoe Springs 8888 BTO
Here are TWO (2) Newly Made HO Slot Car Aurora G+ G-PLUS style Pick Up
Shoe Springs, replaces part #8888. NEWLY MADE B.T.O. Better Than
These new G-Plus pickup shoe springs are made in the USA
from .007" beryllium copper. There are 9.625 coils per spring at an
uncompressed spring height of .225".
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 can be used in the Aurora
G-Plus chassis as well as all the Aurora Super MagnaTraction style
chassis which includes the Speed Shifters, Blazin' Brakes and Cat's Eye.
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. Another spring is
available with an uncompressed spring height of .200" 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.
