Fabtech 07-15 GM 1500 4in Front Dirt Logic 2.5 Reservoir Coilovers - Pair

Fabtech is well-known for their suspension components, especially those built for serious off-road use. These Dirt Logic 2.5 Reservoir Coilovers are a prime example, developed from their desert racing experience to offer exceptional performance. They are designed to provide incredible dampening capacity, making them ideal for aggressive off-road driving and a variety of coilover applications. This pair is specifically built for 4-inch lifts on 2007-2015 GM 1500 trucks, including models like the Chevrolet Silverado 1500 and GMC Sierra 1500.

These coilovers feature a robust 2.5-inch diameter stainless steel body, housing a 2.25-inch diameter billet aluminum piston and a 7/8-inch NitroSteel black piston rod. This construction is built to withstand demanding conditions. The cold-wound coil springs are preset with proper preload, meaning they are a bolt-on installation without needing further adjustments for basic setup. The 2.5-inch diameter aluminum reservoir, connected via a -8 stainless steel O-ring hose, allows for additional fluid capacity and improved cooling, which is crucial for maintaining consistent dampening during extended, hard use. They also feature 5/8-inch spherical ball mounting ends for smooth articulation.

With an extended length of 20.58 inches and a collapsed length of 15.83 inches, these coilovers offer a 4.75-inch stroke. The top mount is designated TP and the bottom mount is OSBP. These coilovers are built to go solid without breaking, settling, or bowing, ensuring durability. While these are a significant upgrade for off-road performance, remember to consult the manufacturer's installation instructions for specific details regarding mounting and any other components that may be required for your lift setup.
