Always the correct part
The Yeah Racing 100mm Desert Lizard Two Stage Internal Spring Shock is a great scale upgrade for your truck. This shock kit includes a full set of springs and machined pistons that will allow you to get your truck setup right, no matter how heavy your truck is.
These shocks can be setup with either a droop or a sprung configuration. A sprung setup will generate more flex and more suspension travel. A droop setup will allow your truck to sit lower and will support the weight of the truck better, but will generate less flex. Plus, the triple O-Ring sealing cartridge will help to prevent oil leaks at the shock shaft.
NOTE: The pre-installed spring combo is for heavy rigs. Yeah Racing recommends experimenting with different spring combinations to find what works best with your rig weight and tire combination.
