Front 4.0 Smooth Body Shocks for Dodge Ram 2500/3500 (1994 – 2013)
(Sold as a Pair)
These 4.0 shocks do not bolt directly into your factory mounts. They require Thuren towers, which can be purchased separately at Thuren Fabrication.
Important Installation Notes:
Modifications Required: Installation of the 4.0 shocks will require trimming the factory coil buckets at both the top and bottom. We strongly recommend bracing both the upper tower (on the inside) and the lower mount around the spring perch, especially if you plan to engage in full race mode.
Clearance Check: It is crucial to cycle the suspension and check all clearances, as these shocks are a tight fit. This is a labor-intensive build, and the coil buckets will need to be braced to prevent flexing. The type of off-roading you plan to do with these shocks will damage factory mounts if they are not properly reinforced.
Shock Features:
These 4.0 shocks feature a large AN 10 hose with a lowered reservoir port, enhancing compression at full travel. Designed for the Dodge Ram owner who wants to push their truck to its fullest potential, these shocks are ready for anything from daily driving to extreme off-roading.
Valving is available in two options:
Full Send Mode: For those who want maximum performance.
Moderate Damping: For a plusher ride with more moderate damping.
