This is an optional Team Associated 12mm Big Bore Front Medium Spring Kit, and is intended for use with the Team Associated B4.1, B44.1, T4.1, SC10 and SC10GT 1/10 scale vehicles equipped with the optional Team Associated 12mm Big Bore Shocks. These springs have more coils for a given spring rate which improves the rate tolerances. The springs are also black oxide coated to reduce corrosion without affecting rate tolerances.

NOTE: To use these springs in the front of a 1/10 truck application, longer 12mm big bore spring cups are required, such as the +5mm and +9mm cups included with ASC91310. 

Includes:

• ASC91328: 12mm Front Spring (White/3.30lbs)
• ASC91329: 12mm Front Spring (Gray/3.45lbs)
• ASC91330: 12mm Front Spring (Blue/3.60lbs)
