This is the Associated Monster GT Red Firm Spring Set. These Red springs have a spring rate of 5.95lbs. These provide additional support for the BIG Monster GT truck. Use these springs to fine tune the handling of your MGT truck. Firmer springs can help improve handling like cornering and landing from big jumps.
For reference, the Monster GT comes from the factory equipped with soft blue springs rated at 4.40lbs. We try to stock all 3 of the Associated Option springs (Gold, Red, & Copper) for the MGT so that customers can purchase the different spring sets and have them on hand for fine tuning of their suspensions under different conditions. See the other upgrade springs we stock for the MGT.
REMEMBER: These come as 4 springs per package. You will need 2 packages to fully equip all 8 shocks on your MGT truck.
