D2 RS Series (RS):

The RS Series suspension kit is D2's most popular coilover. Featuring a 36-way damping and rebound adjustable monotube design, RS Series coilovers are perfect for the modified street car that also sees occasional track days. This coilover has separate height and preload adjustments allowing for optimal suspension tuning while maintaining full strut travel at all times.

D2 DRAG Series (DR):

D2 DRAG Series suspension kits are designed to help you reduce your 1/4 mile time through the use of drag-specific valving and spring rates which increase your car’s traction properties. D2's race-proven drag coilovers feature a 6061-T6 aluminum construction, corrosion resistant shock bodies, and retain 36 ways of adjustment.

D2 RALLY Asphalt (RA):

D2 Racing RALLY Asphalt suspension kits are built using steel mounts, elongated spring and stroke with matched dampening properties, and 44mm pistons to maintain performance and endurance during long-term use. These coilovers feature an inverted monotube strut design and 36-way damping adjustment designed to withstand the toughest rally conditions. D2 Rally Asphalt are adjustable -0.5" to -3.0" from factory ride height.

D2 RALLY Gravel (RG):

D2 Racing RALLY Gravel suspension kits offer steel mounts, elongated spring and stroke with matched dampening properties to compensate for the rigors of off-road rally competition. Additional features include an inverted monotube strut design, 36-way damping adjustment, 55mm piston shock bodies*, and hardened rubber top mounts to reduce noise and improve ride quality. D2 Rally Gravel coilovers are adjustable +/- 1.25" from factory ride height.

D2 DRIFT Series (DT):

D2 DRIFT Series suspension kits provide you with ultimate control over your drift when you need it most. These coilovers feature an inverted monotube strut design* and 55mm pistons** which allow them to maintain peak performance under extreme conditions while maintaining 36-way adjustability. Specially designed mounts, helper springs, and drift-spec spring rates with matched valving result in a high performance coilover that is the standard for many of today’s top drifters.

D2 GT Series (GT):

The GT Series was developed for ultra high performance street cars that also see double duty as weekend track cars. The GT Series features more aggressive spring rates than the D2 RS Series street coilovers, and comes equipped with external nitrogen reservoirs to allow for independent adjustment and fine tuning of compression and rebound. The GT Series is D2's ultimate street/track coilover system.

D2 R-SPEC Series (SPEC):

D2 R-SPEC coilovers are the ultimate suspension system for the serious race competitor. Premium construction, race-spec spring rates with matched valving, and remote reservoirs make this D2's top-of-the-line coilover. This system allows you to fine tune your shock’s compression and rebound independently while helping to maintain acceptable shock oil temperatures under the most demanding race conditions.
