Once the desired valving is in place, the unique double-adjustable design (with adjustable low-speed bleed) allows for fully independent control over the compression and rebound characteristics. With all these adjustability options, MOD Series shocks achieve an expansive force curve capability and an unprecedented level of tunability. The shocks also feature mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas, and the base eyelet is indexable, so you can unbolt and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks, MOD Series coilovers are 100 percent dyno-tested and serialized. Order the kit recommended for your vehicle.
