i'm getting ready to replace the shocks in my truck (07 mark lt) and was wondering if anyone knows if there is a significant ride difference in factory base payload shocks and factory sport-tuned shocks? my truck came with the sport-tuned ones and the ride is a little firmer than i like. i guess i'm hopeing that if i go with base payload shocks, it might ride a little softer. i don't haul with it, so that's not an issue. any help is appreciated.
