Current KING Shock lead times are about 4-5 months. Be sure you're ready to wait that long before ordering.

  • Our extremely advanced shock tuning is included in the listed price.

Consider adding Shock Boots to protect the shock shafts. With exposed shock shafts, regular Off-Road, and winter ice and snow conditions where they gravel and salt roads, can quickly ruin shocks. The gravel from other vehicles in front of you or from your front tires, bouncing around under your truck, can chip the shock shaft. This will cause the shocks to leak, and this is not covered under warranty. Mud and salt dried on the shafts, can penetrate the seals during use, and this is also not covered under warranty.

    These shocks make an astounding improvement in almost every single aspect of the trucks handling. On road, off road, steering response, stability, etc. You name it. The improvement is massive.

    If there is any questions before placing your order, PLEASE call Andrew 541-508-9703 or E-mail Don @ to discuss tuning or anything ahead of time.

    You pay a LITTLE more for these shocks through us, compared to some other retailers, but you are getting the most advanced internals/valving that has taken many years to develop, plus some small but valuable upgrades. Worth the extra coin!

    Our wide range of valving options has been developed over years of research, theory, and real-world testing technology found in the latest Motocross shock internals and adapting that design to allow heavy Dodge Diesel Trucks to perform like no other pickup out there.

    Every internal shock design has had focus placed on giving the best ride for everyday driving and smaller terrain as well as adding control and resisting bottoming out on the larger impacts.

    By strategically placing multiple valving zones inside the shock and creating a true speed-sensitive valving setup. Smaller impacts utilize the soft-zone valving while larger impacts push through this zone and use the stiffer tuned zone(s).

    This type of valving is specific to each individual vehicle and requires precision down to the last .001” Shim. This level of performance is unmatched and will not be found on an off-the-shelf universal “race” shock.

    - Stage One - On highway performance is smooth and responsive. Valving is also light enough to completely absorb large potholes, highway expansion joints, and excels on small choppy terrain. 

    Because Stage One Valving is the lightest setup offered, it can still bottom out as you drive more aggressively off-road. Performance, comfort, and speed will double over that of the stock shock setup.

    - Stage Two - Top notch highway performance with a sports-car-like feel can be achieved with this level of valving. Large potholes, whoops, and ruts will be absorbed easily. However, the smaller bumps will have an entry-level feel to them with this set
