I chose these over a $1000 set of adjustable control arms. They do exactly what they're supposed to do, but when you're riding off-road, they're prone to hitting. However, one thing is clear, they are LONG-LASTING! I mean obscenely long-lived. They are much stronger than bolted blocks. You can adjust the pitch/caster angle if you have 1"-3.5" stroke. Anything less than that and they are outside of regulation. Significant improvements in drivability.
