So...I know it's popular and lots have done it, but...I installed my Hellwig 7709 Sway Bar last night, and I must say, what a tremendous upgrade!
I bought it a few weeks ago but didn't make time to install it. Then, last weekend, I drove to Asheville, NC. If any of you have driven I-40 east into Asheville, then you know that there are miles and miles of narrow curves as it winds through the Pigeon River Gorge. Although I have the usual roundabouts and on ramps here in Indianapolis, that drive to and from Asheville reminded me of why I bought the Hellwig and gave me much regret for not installing it before the trip. When the Ram rolls as you turn through the curve, it gives you a sense that you're coming in way too hot and that you're going to lose control. Even under control, you're pressed against your seat bolsters and your horizon tilts considerably.
The Hellwig requires 15mm sockets to remove the frame brackets around the OEM bar, two screws per side. The end link bolts are tricky. They have to be held from rotating with an M8 socket while you're turning the nut with an 18mm wrench. Torque isn't high, so you don't need much leverage. Maybe at first, to break the nut, you might want to use a deep well socket. Hellwig supplies stainless steel socket head cap screws to replace the OEM hex head cap screws for the brackets. I'm guessing you could reuse what you have. I chose their SHCS option. They require 25-30 ft-lb of torque, use a proper tool if you have it.
Be sure to lubricate the rubber bushings before installation. They're split, so you pull them apart and over the bar. I imagine over time that you might want to go back and regrease periodically.
I chose the middle of the three holes at the end links. You can feel the reduced roll immediately, at any turn of the steering wheel. Parking lots, curves, intersections, roundabouts, on-ramps, lane changes -- EVERYWHERE! The cab and truck are much more stable. I'd say it's a 50-70% reduction in roll. You no longer feel pressed against the bolsters and you don't get that mild apprehension when you make a sudden change of direction. Planted and confident.
To me, this is the #1 FUNCTIONAL upgrade you can make, and it's a bargain under $275.
