Review on Enhance Performance and Comfort in Your Ford F150 4WD with the Roadmaster Active Suspension 3611-YHD by Kevin Ballard

My 2021 King Ranch PowerBoost has a maximum payload of 1316 pounds (very little for a new truck) and I needed more confidence when towing our 2022 Rockwood Minilite 2509S. trailer) I have an E2 WDH 10,000lb and while the hitch height is set perfectly (before adjusting the bars and shim) there is a slight reading deviation, almost to the bottom. Simply put, I needed more confidence for the rear. Axle load and support as 2 leaf springs, FORD decided to upgrade to its "Max Trailer Tow Package" and Package #7350 GVWR. I replaced the front and rear FX4 shocks with FOX 2.0 Ford Tuned by TC Customs and upgraded the tires. (275 60R20) on E-Load tires (295 60R20). Now that my PSI tire was set to 60 cold (80 max), I needed more reassurance. Sign in to RAS. I spoke to RAS support and at YHD they said the max spacing can be set to 2.5mm or a nickel and cent thickness, which is what I did. Installation was very easy, the added fender offsets are useful too as 2021 has automatic headlight height sensors on the rear axle on the driver's side which the RAS for the fender would have trouble with. Now, loading my trailer, hitch and WDH weights, my front and rear wheel arches are at 40 1/2 (even) and the front axle has gained 40 pounds curb weight. The rear still holds 600-700 pounds, but with the RAS I tow with confidence and control. I also added a Timbren SES in place of the stock bump stop for added comfort and control when towing. If you drive a 2021 F150, I highly recommend installing RAS, even if you pull very little. With and without a load, handling, comfort and control are greatly improved. 10/10 highly recommended.
