# Fabtech 01-10 GM C/K2500HD C/K3500 Rear Dirt Logic 2.25 N/R Shock Absorber The best shocks only get better with all new Stainless Steel and Aluminum construction. High grade 304 Stainless Steel shock bodies eclipse all other shocks on the market for maximum corrosion resistance. Each Stainless Steel shock body receives a finely detailed machine finish for a stunning appearance. Dirt Logic Stainless Steel reservoir shocks have been upgraded with black anodized 6061 Aluminum reservoir bodies. This includes both piggyback and remote reservoir shocks. The Aluminum resi construction allows for greater heat dissipation thereby keeping the shock cooler to reduce fade during aggressive offroad use. Finally each Dirt Logic piston rod has been upgraded to a NitroSteel(R) material that is super hard while providing increased corrosion resistance compared to chromed piston rods. Get the finest ride with maximum corrosion resistance only from Dirt Logic shocks. In addition to the specific Dirt Logics for each suspension system, there is also a line of universal Dirt Logic shocks available in reservoir and non-reservoir styles, ranging from 8 to 16 inches of stroke. These universal shocks are sold with universal hardware kits for easy installation. Dirt Logic 2.0 and 2.25 shocks feature urethane bushings in the mounting points to reduce road noise and rattling associated with spherical bearings. Dirt Logic coilover shocks utilize spherical bearings at each end for increased strength along with urethane misalignment cups in the top caps. The misalignment cups keep the road noise transferred through spherical bearings to a minimum. Dirt Logic 2.5 and 4.0 coilover shocks use coil springs made to the highest quality standards possible. All Dirt Logic coils posses the ability to go solid without breaking, settling or bowing. All Dirt Logic coilover shocks come preset with the proper amount of preload so they can be bolted on without any further adjustment necessary. Dirt Logics are available with or without an external reservoir. - Billet Aluminum Top Cap And Rod End/Stainless Steel Body - Urethane Bushings Reduce Noise And Rattle - Outstanding Performance And Longevity - Tuned And Custom Fit Per Application This Part Fits: Year Make Model Submodel 2001-2005 Chevrolet Silverado 2500 HD Base 2001-2006 Chevrolet Silverado 2500 HD LS 2001-2008 Chevrolet Silverado 2500 HD LT 2007-2008 Chevrolet Silverado 2500 HD LTZ 2003-2008 Chevrolet Silverado 2500 HD WT 2007 Chevrolet Silverado 2500 HD Classic LS 2007 Chevrolet Silverado 2500 HD Classic LT 2007 Chevrolet Silverado 2500 HD Classic WT 2002-2005 GMC Sierra 2500 HD Base 2001-2002,2006 GMC Sierra 2500 HD SL 2001-2008 GMC Sierra 2500 HD SLE 2001-2008 GMC Sierra 2500 HD SLT 2003-2008 GMC Sierra 2500 HD WT 2007 GMC Sierra 2500 HD Classic SL 2007 GMC Sierra 2500 HD Classic SLE 2007 GMC Sierra 2500 HD Classic SLT 2007 GMC Sierra 2500 HD Classic WT ## Details - **Price:** 492.31 CAD - **Vendor:** Fabtech - **Type:** Shocks and Struts ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 492.31 CAD | In stock | ## Images - Photo - Primary - Photo - Primary --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/fabtech-01-10-gm-c-k2500hd-c-k3500-rear-dirt-logic-2-25-n-r-shock-absorber) > Updated: 2026-06-27
