Designed for the AAM American Axle found under Heavy Duty Dodges, the Carli Axle Truss is a crucial component for the avid off-roader that routinely puts their truck in extreme situations. The factory AAM axle is susceptible to bending from the forces encountered in normal or extraneous off-road activities, leaving the truck with a "smile" that leads to worn tires and steering components. At the heart of the Truss is an internal network of 1/4" thick x-bracing and reinforcement ribs that zig-zag down the length of the axle. Coupled with the axle tube saddles, Upper C Gussets, Lower C Doublers, and CNC manufactured plates, the Carli Fabricated Truss will keep your axle straight and intact for that next blast down a desert trail.
This Truss is NOT a direct fit item and will require skilled fitment and installation. Cutting and grinding will be required in the fitment process. This fits 2003-2012 Ram 2500/3500 4wd trucks.
This item requires installation by a trained professional. Welding is required to secure the truss to the axle. Knowledge of dissimilar metals: Cast, Forged, and CRS, is highly recommended.
Included with every Fabricated truss are Upper C Gussets & Lower C Doublers to ensure no weakness of the factory Outter-C design is left unsupported.
Due to limited production, Thuren Fabrication items cannot be expedited. If expedited shipping is selected, we will credit back the shipping difference and ship via standard Ground shipping. Thank you for your understanding!
The axle on the 2014+ Ram 2500/3500 is a whole different animal from the previous generation. The large pumpkin, CAD bracket and outer C’s don’t make for an easy welding job. That said, we’ve designed a truss kit that runs a 1.75″ Diameter 0.120″ wall thickness tube that’s CNC Cut/Bent to match the knuckle profiles while skidding the pumpkin. Included with the truss kit are two 1″ OD stand-off tubes that bridge the distance from the truss tube to the main axle tube on the passenger’s side (long side) then plates to enclose the entire truss. Lastly, we include “Upper C” Gussets to plate the outer C upper to the bottom of the coil buckets.
This is the strongest truss kit on the market and requires SUBSTANTIAL fabrication knowledge/ability to install. There are no instructions; take it to a fabricator with extensive knowledge in welding differentiating metals.
