I have the OEM steering stabilizer (even though I have a Falcon one in the box ready to install) and feel no need to replace it.
The other BIG improvement for me was adding a full SteeringSmarts setup:
- Sector Shaft Brace With Frame Side Track Bar Reinforcement Bracket,
- Front Adjustable Track Bar,
- YETI XD™ Pro-Series Aluminum Tie Rod, and
- Drag Link with Griffin XD™ Attenuator
Before this I always had to micro-correct the steering to keep going straight on the highway. Also, the steering wheel had often be either at 11:55 at times or 12:05 some other times to track straight. Now it stays at 12:00 all the time and tracks perfectly straight. Not sure which exact component did the trick, but I suspect the Griffin or the Sector Shaft.
