Who has installed them in a 9 1/4? Are they necessary for an 11 second car? Thanks, John

The real need for the eliminators has NOTHING to do with the c-clips - the clips don't fail, they don't pop out, and the button doesn't break off the end - it's a failure elsewhere that is the problem. What breaks is the axle itself - an axle of that strength would fail, c-clip or not. Granted, once the axle breaks, then you can lose the wheel/tire and the problem starts, but it wasn't the clips that failed. Put in strong enough axles and the clips are never an issue. Sometimes the whole diff explodes; again, nothing to do with the c-clips. As to your situation, I'd look into stronger axles for the most bang-for-the-buck. If your wallet allows, the strongest way is as others have mentioned - new ends, bearings, and axles.
