For extended joint life, we offer boots at an additional cost of $9 per joint, guarding against debris while allowing for added lubrication. Don't fall for cheap imitations with inferior materials and joints, as initial savings can lead to more significant time and money investments when those subpar joints wear out. Our 303 stainless steel spacers guarantee strength and corrosion resistance.
Once installed, this kit enables full adjustability of camber and toe at ride height. We take pride in using American products and materials exclusively, avoiding cheaper overseas alternatives. Notably, our lower radius rods made from 7075 aluminum offer remarkable strength compared to 6061, ensuring they won't elongate, stretch, bend, dent, or scratch. Plus, we back our aluminum parts with a lifetime warranty, providing you with peace of mind and unbeatable performance. Upgrade to the best; choose Ct for uncompromising quality and durability.
Why do we choose 7075 over 6061? The weakest part of the rod will will always be the area that surrounds the uniballs, or where a joint is threaded in. The area that surrounds the uniballs is often severely limited to how much material we can have before it starts to interfere with the trailing arm or other components, this is the biggest stress point of the radius rod as during bottom outs the lower rod has a tremendous pull force on it. On a threaded link we're limited to the material that is in the threads itself, we need maximum strength there as well to not pull the threads out of the rods, or compress the threads over time making the joints wobbly in the rod becoming loose. 7075 is also known for its flexibility and its memory, with a direct impact it will deflect up to 10% and spring back to its original shape, the flexibility and memory of this material is why it's used as the main structure of aircraft wings. Furthermore all of these reasons are why this material is used as suspension "link material" for rock crawlers and rock bouncers as well as trailing arms and control arms on trophy trucks, almost never 6061.
