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.. This Toyota 4Runner suspension system features Fabtech?s proven IFS technology with extended length ductile iron steering knuckles for proper electronic stability control functionality. Heavy duty 1/4" thick steel lower control arm crossmembers provide superior ground clearance while the integrated front differential skid plate adds protection to the drivetrain for offroad use. The front suspension is controlled with Fabtech?s legendary stainless steel Dirt Logic 2.5 Resi Coilovers for outstanding damping capacity with a superior highway ride. Rear lift is accomplished with steel coil spring spacers that retain the Toyota 4Runner coil springs for a smooth ride. Heavy duty Fabtech control link arms replace the factory arms to re-position the tire in the wheel well with the additional ride height. A stout 1/4" thick steel bracket relocates the rear Track Bar to keep the vehicle tracking proper. Rear shocks include the Dirt Logic 2.25..
