WAIT! Before you make a 4 Link Change DO THIS!

Before you move a 4 link bar or ladder bar, you need to know exactly where the car is right now. Otherwise you are not tuning, you are guessing. That leads to a Bar change gone wrong! In this video I walk through my Before and After 4 Link Bar Change Checklist and explain what to check before making a bar change, what to document, and what has to be reset after the change so you actually know what the car responded to. We cover ride height, tire pressure, fuel level, pinion angle, driveline angles, shock installed height, shock travel, rear housing square, wheelbase, 4 corner scaling, ARB connected versus ARB floating, preload, and why the change is not finished just because the bar is bolted into a different hole. ✅ Printable checklist and free Suspension Tuning Questionnaire: https://www.samsonperformance.com/4-l... ✅ More free drag racing resources: https://www.samsonperformance.com/res... 🔥 Remote and in shop suspension tuning with KevinWilsonSBC: https://www.samsonperformance.com/sus... ✅ What are your thoughts?
