Product Details

The QA1 Proma Star DD301 is a premium double adjustable coilover shock designed for serious performance applications. This shock features a machined aluminum body with a bright anodized finish and a heavy-duty 5/8" chrome-plated solid piston rod that eliminates flex under demanding conditions.

Advanced 324-Position Adjustability:

The double adjustable design provides 324 distinct valving combinations through two independent adjustment knobs—one for compression damping and one for rebound damping. This level of control allows you to precisely tune your suspension to match your driving style, track conditions, or performance needs.

Key Features:

  • Machined aluminum body with bright anodized finish for durability and corrosion resistance
  • 5/8" chrome-plated solid piston rod eliminates flex and ensures consistent performance
  • Double-lip piston seals with wiper seals prevent seal drag and keep contaminants out
  • Accurate piston-to-cylinder wall seal improves valving consistency and longevity
  • Deflective disc valving for increased sensitivity and precise control
  • Each shock is dyno tested and serialized for quality assurance
  • Revalvable and rebuildable by QA1 authorized service centers
  • Includes aluminum spring cap, spring seat with washer, and locking ring
  • Compatible with Teflon/Kevlar race bearings (as equipped on this model)
  • Proudly made in the USA

Specifications:

  • Compressed length: 8.63 inches
  • Extended length: 11.13 inches
  • Recommended ride height: 9.5 to 10 inches
  • Recommended spring length: 7 inches
  • Mounting style: Eye-to-eye with bearings

Ideal for street rods, high-performance street cars, autocross, drag racing, and road racing applications where precise suspension control is critical. Sold individually.
