After looking long and hard at the available options in the marketplace for Shock Towers, and the options aren't all bad, we came up with a tower that can withstand more than the rest. By using CNC Bending to it's fullest potential (they each have 7 bends) we were able to make them ideal for strength & support. We have also accepted that 1 size dosen't fit all and made them 6 different ways. First there are models for 2" wide frames and models for 2 3/8" and wider. Secondly, they are all available in 3 above the frame heights, 9 3/4" (10-12" coilovers), 12" (12-14" Coilovers), and 14 1/4" (14-16" Coilovers). These are basic guidelines, MEASURE your projected height +/- frame height over the axle to determine what would work best for you. As is the norm at Ruffstuff, don't look for ours to be a basic model, we took nearly 2 years to develop these and we think the additional strength and lack of full length welds combined with the very fair prices will tell it all. 2 Models are ready to ship today (8/21/07), 4 more will be available over the next 6 weeks. These are all sold in pairs. BTW, they are 1/4" thick too!
