From the Manufacturer:
Westcott Designs 4Runner TRD PRO FOX lift kit for the 2021-’23 model years. The suspension has been redesigned and re-valved for 2021-’23 model years. They also redesigned the spring and lower spring perch as well. We have been doing testing for the last year on this set up and it is dialed in to say the least! Our kits are the highest quality kits on the market. We manufacture everything in house to make sure the quality is top notch. Our TRD PRO lift kits look nicer then OEM. If you did not know what to look for you wouldn’t even know it wasn’t factory. Our front kit is all billet machined out of solid stock aluminum and hard anodized in black to look factory. As for the rear, we CNC machine all of the parts and hard anodize them to have a great look and to maximize the life of them to make sure they outlast the vehicle. We don’t agree with taking short cuts and making parts out of plastic in the front or rear that will just break down or fail over time. I don’t know about you but I know I would not spend $55k on a vehicle and replace parts with plastic parts especially when they are under a lot of load.
 
This kit provides the following lifts:
2021-’23 4runner: 2” (front lift) and 1.25” (rear lift)
Lead times for new orders vary from 1-2 weeks for raw finish kits and 2-3 weeks for black anodize finish kits
