Are spring rates for losi springs as simple as they look? The higher the number the more weight it takes to compress the spring. So a 5 would be a stiffer spring than a 4?

This is for 10th scale right?

FRONT BUGGY SPRINGS
Losi Part #
A-5128 2" Spring 2.5 Rate (Red)
A-5129 2" Spring 2.9 Rate (Orange)
A-5130 2" Spring 3.2 Rate (Silver)
A-5132 2" Spring 3.5 Rate (Green)
A-5134 2" Spring 3.8 Rate (Blue)
A-5135 2" Spring 4.1 Rate (Black)

REAR BUGGY & TRUCK (front and rear) SPRINGS
Losi Part #
A-5146 2.75" Spring 1.6 Rate (gray)
A-5147 2.75" Spring 1.8 Rate (White)
A-5148 2.75" Spring 2.0 Rate (Yellow)
A-5150 2.5" Spring 2.3 Rate (Pink)
A-5152 2.5" Spring 2.6 Rate (Red)
A-5154 2.5" Spring 2.9 Rate (Orange)
A-5156 2.5" Spring 3.4 Rate (Silver)
A-5158 2.5" Spring 3.7 Rate (Green)
A-5160 2.5" Spring 4.1 Rate (Blue)

No its for 1/8 scale. My question was about what the rates mean not the different spring rates.

The higher the number, the stiffer the spring or the harder it is to compress.

Thank you.
