Take your Toyota up a level Premium Aluminum Link Kit for the 2003+ 4Runner 2007+ FJ Cruiser, 2008+ 200 Series Land Cruiser, and 2003+ Lexus GX This kit is a great replacement for weak factory upper and lower control arms and is designed to correct vehicle geometry after lifting the vehicle. The double adjustable ends mean you can use this on nearly any height of lift kit. These links are light, strong and have been engineer to increase off-road ride quality and performance. The polished aluminum also stands out contrasted to the dark vehicle frame for a high end look. The 4Runner 5th Gen ALUMINUM Rear Link Kit starts with our 2.0" outer diameter, aerospace grade 7075 Aluminum lower links and 1.5" OD upper links. The aluminum links are out-fitted with time-tested Rock Krawler brand Krawler Joints with a 1.25" thread on the lowers and 7/8" thread on the uppers with matching jam nuts. These are the same joints shipped in nearly every Rock Krawler lift kit so you know they stand up to the test of time and abuse...not to mention there are millions of them on the streets. Each link is threaded with both a Right Hand thread and a Left Hand thread at opposite ends so it is easy to adjust the length for fine tuning. We've also included wrench flats on each end of the aluminum link so you can easily tighten your jam nuts without marring the aluminum. The real advantage of our aluminum link suspensions is the weight savings. Each link only weighs a few pounds versus steel links which can be dozens of pounds. This weight savings means better fuel mileage, less wear and tear on your vehicle and it's components, easier install and less maintenance. Aluminum also is naturally rust resistant so you don't have to continually paint them if you scratch them plus aluminum's natural shininess adds so much curb appeal to your vehicle. A big benefit to 7075 aluminum also is that the material has a memory and will return to its natural straight shape after taking a big hit. While steel control arms will dent and stay bent, 7075 aluminum will remain straight for years and years of constant beating. This is most important on lower links that really take the hits on rocks. Springs, shocks, limit straps, sway bar extensions, and extended brake lines are not included in this kit and will be needed.
