Quote: If you can dig up a picture of Joe Aluise's Max Wedge A/SA car from around 2000, it might surprise (disturb?) you to see slapper bars on it... and it was probably the fastest Mopar Stocker on the planet at that time, too.
If you know how and take measures to control the extra leverage of a slapper bar, sure you can make them work. On a heavier car its easier and a lighter car its harder. On a lower HP car its easier and a higher HP car its harder.
No Doubt, the front Short segment of the mopar spring makes the use of a slapper bar a issue when it comes to a high HP/torque build. Even a "non slap" SS Machine bar can over rotate a rear axel assembly causing problems.
