40mm rear drop knuckle designed to add rear end grip and correct suspension geometry for drifting and racing. Relocated mounting locations of the adjustable control arms allow the rear alignment to remain optimal throughout its complete range of movement resulting in added tire contact for higher grip and better tire wear. With the improved geometry, factors like toe and camber gain are better controlled and can be fine tuned for the most grip available. Designed and built in house, using precision chromoly rod ends for high strength and a long service life. Our knuckles utilize a newer style Lexus bolt on hub assembly for ease of service or replacement. Built in dual caliper mounting uses stock Toyota/Lexus calipers and rotors. We also retained all factory eccentric hardware in the subframe for dialing in alignment settings with slight changes in track conditions in seconds. We've tested this setup running up to an 18x10.5" et +25mm with no interference to any of the arms. Rear kits include all required hardware and optional new hub assemblies. *this product is for off highway competition use only* **due to the current pandemic please allow for 2 week lead time on all angle/knuckle kits**
