Hey guys! Been awhile since I last posted. I'm about ready to lift my 78K5. I still haven't decided between the 4 inch lift or the 6 inch, but I'm close. As soon as the tax return gets here, I'll be ready to buy. My question is this....Who makes the springs with the teflon pads between each spring, and with the rounded edges? I want something that is good on-road, as well as off-road, cause my K5 is used 80 percent of the time on-road. Thanks for the help. Eric78K5 K5-Because Size Matters!
