Gears and lockers on the JKU..
The RockJock Antirock will always be in my top five.
If you don’t have AntiRock you are not right
Steer Smarts drag link, tie rod, and track bar
Love steer smart
The one I like the most is the Savvy Midarm suspension setup.
I'd say that teraflex monster track bar. Zero wobble with heavier tires too.. First time I've almost gotten a speeding ticket in over a year! Zoom zoom :)
