Product Installation Instructions

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 setup.

Off-road performance and bottoming resistance is roughly 10% over that of Stage One Valving.

- Stage Three - This is the most common valving design we use and often is the most requested. With the right components to complement this valving setup, the performance gains could be huge! There is no comparison to the stock configuration with stage 3 valving.

Large potholes, curb-sized bumps, rutted dirt roads, and sand whoops are no longer a problem. More speed is required to push through the stiffer valving offered here and therefore smoothing out the ride over this type of terrain.

- Stage Four - This level of tuning is where the off-road performance really increases and desires speed to do so. It is strongly recommended to install an Axle Truss on your truck at this point due to increased speeds and higher impacts that come up quickly.

On-road performance is far better than a stock configuration but will start to feel more firm on the large potholes and bumps in comparison to Stage Three valving.

- Stage Five - An Axle Truss is mandatory at this point simply due to the potential speeds that are required to utilize this level of valving. With this level of valving the smaller bumps are not absorbed as easily however bottoming out is heavily resisted.

Large potholes and small speed bumps will have the same feel as the stock setup but will be soaked up with speed to push through the valving configuration. The highway feel will be well balanced but still resemble that of a stock truck setup.

- Stage Six - This is where the Race Speed Performance enters the game. Smaller square-edged bumps will be more pronounced but the bigger whoops and rollers crave more speed. Larger sand whoops can be skipped across the top with the right application of skill, speed, and line choice.

Stage Six valving can truly test the skill of any driver and allow your truck to obtain jaw-dropping speeds in the roughest of terrain. Driving your Dodge Ram at the speeds applicable to this valving will require immense off-road driving skill, experience, and supporting component upgrades.

Highway driving is compromised when contacting large potholes and bumps but freeway expansion joints are still more balanced over stock suspension.

I found the perfect setup; Thuren King 2.5 Resy’s

Because they are freekin’ experts on these Ram trucks. I was looking to upgrade my King 2.0’s (purchased from TF) and their tech team spent an hour on the phone with me feeling out wants and needs. The result was a 2.5” Reservoir King shock with Stage 3 valves. It’s perfect. Took the spring out of the back end and tightened the front up just enough. If debating the 2.0” vs. 2.5”, don’t buy small and expect big results. The 2.0’s were nice. The 2.5’s are awesome.

Thank you, Thuren Team!

Ram 3500 Suspension Game Changer

I am running Thuren's 2.25" front coils, sway bar, & track bar with the Thuren tuned King 2.5" shocks [front & rear stage 3 valving]. These shocks are an absolute game changer as far as off-road handling. I have taken rough potholed washboard trails like the Old Mojave Road and the 27 mile trek out to the Racetrack Playa in Death Valley at fairly high speeds and the truck practically floats over them. It is truly amazing. My family is more comfortable and the truck is not getting beaten up. They are fully rebuildable and depending on how hard you use them, suggested rebuild intervals for moderate+ use is around 25-30k miles. If you are mainly sticking to the pavement & the occasional dirt road, these shocks would most likely be overkill & the Thuren tuned Fox 2.0s would also be a great choice - but if you plan to really push your truck on some rough roads & trails regularly, these are worth every penny in the performance & ride quality they provide. I run an overland tent/rack setup in my bed, often tow a toy hauler and use rear air bags when hauling heavy loads for work. Ride quality is better than stock all around.

Great customer service

Stopped in and talked to Chris a while back about different options for what I was trying to accomplish. He put together a parts list and I followed his recommendations. Couldn’t be happier with how well the truck works. On road, off road, it handles it all.
