MOST BMW APPLICATIONS AVAILABLE!

AST Suspension is famous for its inverted technology on their flagship 5000 series dampers. Using a 45mm inverted piston or cartridge design increases damper strength in all directions, optimizing cornering and braking forces under any condition. Proven during countless competitions around the world, their design provides an ultra-strong strut and a low frictional resistance.

AST 1-Way 5100 Series (Rebound Adjustable)

  • Floating piston design with high pressure nitrogen means no cavitation around the piston.
  • 14mm diameter internal shaft.
  • 44.5 mm diameter shaft struts, inverted.
  • Steel cylinder body shocks, inverted.
  • High end, track ready suspension.
  • Rebound adjustable (”Singles”).
  • Low friction seal.
  • Adjuster knobs permanently mounted on the dampers.
  • Rubber bushings for ”eye” shock mounts.
  • Optional spherical top mounts.
  • Optional DLC Coated shafts.

AST 3-Way 5300 Series (Rebound, Low & High Speed Compression Adjustable, with a remote reservoir)

AST_5300_Nissan_R35GTR_01

  • High end, track ready suspension.
  • Rebound, Low & Hi Speed Compression Adjustable (‘Triples’), with a remote reservoir.
  • Remote reservoirs allow additional travel, heat dissipation and oil/nitrogen gas capacity.
  • 44.5mm diameter shaft struts are inverted and offer exceptional strength, which in turn reduces geometry change under corner and braking manoeuvres.
  • Aluminum cylinder, threaded body shocks, factory mounting style.
  • New low friction seal on all AST dampers.
  • Spherical lower ”eye” shock mounts.
  • Reservoir with hose or piggyback (piggyback examples: ’08 STI & BMW E36 rears).
  • Spherical upper shock mount assemblies.
  • Synthetic hydraulic fluid.
  • Optional DLC Coated 44,5mm inverted shafts.
  • Optional DDP piston (double digressive).
  • Fully serviceable and rebuildable.
  • Revalvable for specific characteristics.

AST Lowering Springs

34742774745_55274587b4_z

AST Lowering Springs are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency.

Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot peened, phosphate treated and then powder coated to outlast even the life of the vehicle.

  •  Progressive rates on most vehicles
  •  EDC Compatible (if applicable to vehicle)
  •  Each spring is blocked and computer tested prior to shipping, which reduces any settling once installed on the vehicle
  •  Most of our spring applications are TUV Certified and certificates can be provided upon request
