Core RC Big Bore Spring; Med - 3.7 (2)

The Core RC Big Bore Spring; Med - 3.7 (Pair) offers precise suspension tuning for 1/10th off-road vehicles. Designed as a progressive big bore spring, it helps the car float over bumps while limiting body roll through corners for balanced handling. Part number SCH-CR182 (CR182).

Each spring is manufactured with a constant wire diameter to deliver consistent characteristics across the range, with small stiffness increments that make fine adjustments straightforward. The black coating and precision-ground ends enhance durability and seating accuracy. These springs are supplied as a pair.

To use on small bore shocks, optional top converters CR190 and CR191 improve seating (the spring bottom fits regular small bore shock bottoms). Suggested compatibility includes a wide range of 1/10th off-road platforms using big bore shocks, or small bore units when fitted with the converters.
