This is a complete set of super heavy duty springs for the Kraken RC HPI Baja Big Bore shock set. These are a stiffer rate spring than those included with the shocks.

These are ideal for the heaviest billet aluminum or big bore engine builds. These are also ideal if you need a little more spring rate for some of the aftermarket roll cages on your Baja. They are 3.2mm diameter front spring and 3.5mm diameter rear spring, sold as a complete set of four to outfit your Baja!
