SCREWFX46.5

I had the above mentioned product installed on my 2011 f x 4 Supercrew long bed. Initial impressions are very good With the bed unloaded. This is an absolutely fabulous product. I had the dreaded exceleration shudder. Had being the key word Because it is completely gone. I am amazed. I also have increased lift in the rear. Bodyroll is greatly diminished loaded or on loaded. I will report back once I have a significant load in the rear. For now I am pleased with this product. For 400 dollars installed this is money well spent. I understand there's also the added benefit of increased payload.

You can't increase your payload with suspension upgrades. It's just safer to haul your rated payload now. Good to hear it performs well, can't wait to get mine.
