The Carli SPEC 2.0" Commuter 3" Lift Shock Package is a comfort and ride quality focused kit for the 1994-2013 Ram 2500/3500. The 2.0" diameter internal reservoir shock is tuned for on road, highway and daily towing/hauling driving in mind. For those trucks that don't see the dirt, or see it sparingly, this is the perfect kit for your application. The 5/8″ shafts are hardened & chrome-plated steel. These shocks are spaced with a premium 5WT oil to balance lubricity, consistent damping, and the widest available range in temperature variation. The rod ends are constructed of 6061 billet aluminum; inside you will find a high-quality 1-piece bushing and zinc-plated crush sleeves for precision fit and longevity. The cylinder end cap has a unique design as it overlaps the body of the shock to provide external support to the internal snap ring. These shocks serve as the travel limiter for all trucks without our radius arms (and subsequent limit straps installed), ensuring the shock stays together on top out while bearing the load of the axle is paramount. The Remote Reservoir variant adds the separate canister to carry the dividing piston and nitrogen charge leaving the entirety of the body available for extended piston travel. Without getting too technical, a Remote Reservoir will have more suspension travel than an IFP with the same mounting dimensions. In adding this canister, we have spec’d a high quality hose and fittings similar to the one offered on our King shocks.The last high-end touch Carli added is a billet, laser etched Carli reservoir clamp (rear shocks only). This Carli shock package is designed to be matched with a set of Carli's leveling front coils and factory rear leaf springs.
