WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!

Heavy Duty RAS Vehicle Suspension for stable towing
Hauling often with real tongue weight or bed cargo? heavy duty RAS adds strong, adjustable support to help reduce squat and improve stability. It plays nicely with a weight distribution hitch, and some setups may see the rear sit about 1-2 inches higher unloaded and a firmer ride, making it a good pick when loads are frequent or on the heavier side.
Confirm your truck has rear leaf springs; coil-spring rears may not be a match. Some trucks with factory overload springs may require removing the overload per the instructions. Installation is DIY-friendly, but space varies—some installs don't need wheel removal, others go smoother with the axle hanging. Make sure left/right pre-tension is matched.
Heavy Duty RAS can raise the rear about 1-2 inches, adding some rake. Measure your fender heights before and after, then adjust pre-load to the lightest setting that supports your load. If your trailer rides nose-high, fine-tune hitch height or head angle to bring it back to level. Recheck that both sides are matched so the truck sits even.
Choose Heavy Duty RAS if you're carrying heavier loads or pushing max tow. For lighter trailers, Heavy Duty can feel stiff unloaded even at the lightest pre-load, so the standard option may ride better day to day. First, dial in your weight distribution hitch so the truck sits close to level. If the ride feels harsh empty, reduce pre-tension or step down to standard.
Yes, Heavy Duty RAS helps reduce squat and improves stability under load. Users saw the rear sit closer to level and body roll stabilized when towing with a weight distribution and sway control system. Set both sides to the same pre-tension and recheck after your first tow. Don't expect all sway to disappear, but it can be greatly reduced.
