Featuring a threaded lightweight billet aluminum shock body, this kit delivers fully adjustable ride height and independent valving control, making it an excellent upgrade for street, strip, or track use.

The double adjustable design provides 18 positions of rebound and 18 positions of compression on independent knobs, yielding 324 total valving combinations for precise tuning to any driving condition. Adjustments are easily accessible by turning the steering wheel to full lock and reaching in at the base of the shock.

  • Threaded shock body allows 0 to -2 inches of ride height adjustability via spring seat nut
  • Bolt-in compatible with OE stamped steel or QA1 tubular control arms
