Hello all! My frame was not broken yet so I purchased and installed the Bolt-in Steering Box Brace Kit from offroaddesign.com. While on your site, I noticed the Heavy Duty Front Shackles and had a question concerning them. I have a 1973 Chevy K10 Longbed Pickup that I have lifted with Superlift's 2 1/2" springs and urathane bushings front and rear. The front springs are softride however im not sure about the rear. All I know is that I asked for the softride spring kit. After I installed everything, I noticed that the rear sits noticably higher than the front. My main objective in installing them is to raise my front end slightly to compensate for this. This vehicle is used primairly on the street. My question to you is: will the 1/2" difference in length of your shackles cause viberation or excessive wear on my componets or any other inherant problems? Any and all help will be much appreciated. Thank you!
