Kevin,
Pricing and availability will be released with SLR's new website; we are in the manufacturing stage and pricing will be set when all of the components are completed.
SLR has never tested or cycled other manufacturers' suspension lifts. The key to the SLR Suspension Lift is that it is a complete system. SLR does not recommend mixing and matching other manufacturers' suspension components.
Please email SLR directly @ info@spencerlowracing.com if you have further questions. Thank you for your interest and patience.
THE WAIT WILL BE WORTH IT
