Thuren 10-13 4th Gen Dodge Ram 2500/3500 King 2.5 Suspension Kit

The Thuren King 2.5 Suspension system offers improved on and off road ride in your 2010, 2011, 2012 and 2013 Dodge Ram 2500 and 2010, 2011, and 2012 Dodge Ram 3500 truck and a massive improvement in off road capability when paired with the right supporting parts! This system will handle anything from daily driving to whoops at 50-60 miles an hour when valved and speed properly. We highly recommend adding the track bar, sway bar, arms and rear leaf springs to get the most of this system. At a bare minimum we recommend adding the sway bar end links, and ideally the track bar. The system assumes Thuren spec King 2.5 shocks with standard body length, stainless shaft, and blue anodized end caps like pictured. You can order a more custom spec on the shock page, and then piece together a kit. ALL THUREN KING SHOCKS INCLUDING THIS SYSTEM ARE CUSTOM ORDER, MEANING THERE ARE NO CHANGES, CANCELATIONS ,OR REFUNDS. THUREN KING SHOCKS ARE A 8-10 MONTH LEAD TIME. Thuren encourages customers to choose their shock valving based on their needs. Below is a description of each stage. Feel free to call us with questions!  VALVING OPTIONS: - Stage one - Rides unbelievable on the highway and performs great on mild gravel roads. Valving is light enough to completely absorb even the largest potholes, highway expansion joints, and excels on small choppy terrain. Stage one front valving is the lightest valving we have, and can still bottom out easily once you get more aggressive off road. Comfort and possible speed off road is still about double what is possible with the stock shocks. - Stage two - Highway ride is still top-notch, but the suspension will now have a slight sports car type feel to it. Large potholes and ruts are absorbed the same as stage one, but the smaller holes and bumps have a bit more entry feel. Off road performance and bottoming resistance is increased about 10% from stage one. - Stage three - The most common valving design we use. Highway ride is still much better than stock, and with the right components, the off road performance increase is huge. Large potholes, curb size bumps, rutted dirt roads, and small sand whoops are no problem. More speed equals more force to push through the valving and smooth out the ride in this type of terrain. - Stage four - This is where the off road performance really increases, and desires speed. Time to start thinking about a front axle truss, as the off road speeds attained can let the really big hits come up quick. On road ride is still better than stock all around, will start to feel more firm on the larger potholes and bumps compared to stage three. - Stage five - Axle truss is pretty much mandatory at this point to use this valving to it's potential. With this much valving the suspension does not absorb the smaller bumps as easy, and is designed to now really resist bottoming out. Large potholes and small speed bumps are now about the same feel as the stock suspension, but do still get absorbed with enough speed. The highway ride is more balanced than stock, but has about the same feel on average. - Stage six - Pretty much focused on race speed off road performance. smaller square edge bumps will be pronounced, but the bigger rollers and whoops just want more speed. Large sand whoops can be skipped across with the correct line and skill. This valving can test the limits of any driver and let the truck obtain jaw dropping speed in the rough. To drive your dodge ram at the limits of this valving will require vast off road driving skill and experience. Highway ride is compromised when contacting large potholes and bumps, but freeway expansion joints are still more balanced than stock. This kit can be upgraded with sway bar, control arm, and leaf spring options to further improve ride. We HIGHLY recommend adding at least sway bar end links to correct the front sway bar geometry and allow for full droop. A track bar is also highly encouraged. All other options are elective.  COIL HEIGHTS: We offer this with multiple coil options up front. Below are the heights for the different options: THUREN 3" 2010-2013 DIESEL QUAD CAB = 2.875" LIFT 2010-2013 DIESEL MEGACAB = 2.625" LIFT Thuren 2" 2010-2013 DIESEL QUAD CAB = 1.875" LIFT 2010-2013 DIESEL MEGACAB = 1.625" LIFT Thuren XS 2010-2013 Ram 2500/3500 Gas trucks ........... 2.50" lift* 2010-2013 Ram 2500/3500 Diesel trucks ....... 1.50" lift.* 2010-2013 Ram Power Wagon ........................0.75" lift *All MegaCab trucks subtract .25" from the listed height.
