The 3Racing SAK-D651 springs are developed with racing setups in mind, sized at M1.2 x 14 x 34 to match Sakura D6 Sport shock assemblies. These springs deliver repeatable compression characteristics needed when tuning damping and preload for lap consistency. Use them to refine transient response and mid corner balance during setup sessions.
Each spring in the SAK-D651 set is produced to tight tolerances so teams and advanced hobbyists can rely on consistent spring rates across runs. The specified dimensions allow precise interaction with shock pistons and oil viscosity, helping to tune axle load transfer and reduce variance between runs. This makes them a useful element in a methodical race setup programme.
