Ride height is set on the threaded body or the lower mount, and the damping (how firm the shock feels) with the adjuster when the kit has one. Some kits also let you set spring preload and camber at the top mount. The Part details above list what this exact kit adjusts.

Yes. Changing ride height changes camber and toe, so have the car aligned once the height is set and the suspension has settled after a short drive.

The car settles a little over the first few drives. After that, re-check the ride height, the lock rings on the collars and the top-mount hardware, then get the alignment done.

This kit is the maker's DS series. Each series is built for a different mix of street comfort and track grip and comes with its own damper and spring setup, so the series name tells you which tune you are getting.

Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.

It combines spring and damper in one threaded-body unit that replaces the factory strut or shock.

To lower the car, tighten body roll and get corner-balancing and alignment latitude. Call 813-535-5801 for spring rate help.
