Spring Rates - Our default spring rates aim for a "sporty" yet comfortable ride that offers the best parts of a coilover system, without the harsh ride typically associated with their use. We carry standard Silver's springs up to 20k rates, and Swift springs up to 50k rates. 

Super Low Kit - The Super Low Kit is a modified kit that uses a combination of short shocks, shorter springs, or both to achieve a lower overall ride height. In general our standard kits aim for 2.5-3 inches of drop from factory, while Super Low aims for 4.5-5 inches of drop. The trade off is less available travel, potentially stiffer ride, and at full height it will be around 1-1.5 inches under factory height. While most kits can be modified into a Super Low version, there are a few restrictions, please inquire to make sure.

Swift Spring Upgrade - The Swift Spring Upgrade will swap out our standard, included Silver's springs, for premium Swift springs. While the standard springs do a great job all around and have a smooth ride and long lifespan, Swift's offer an upgrade in every way with no downsides. They are lighter in weight, offer more travel for a given spring length, less sag/breakdown over time, more linear throughout their stroke, and available in many lengths and rates to make the perfect setup. They also look pretty nifty! If no custom rates are selected, Swift springs in the default spring rates will be used. 

Rear Extender Upgrade - The Rear Extender Upgrade is a footlong cable extension that attaches to the top of the shock's damping adjustment knob on certain applications. This allows you to route the adjustments to an easier to reach location inside your trunk or hatch area. Typically requires drilling a 1/4 in hole through any body work. Rule of thumb is if you can see or reach the top of your factory rear shocks/struts they are not necessary. Some applications use special adjusters to mitigate the need for rear extenders, if you have any questions on your application, please reach out!



Spring Preload - Standard spring kits will ship with 0 preload, it is recommended to install and drive the kit like this for a few hundred miles to settle and break in the suspension, then reset preload to 3 to 5mm. Swift Spring upgrade kits will ship with preload pre-set as they will have next to no sag or break-in period.
