SuperCoils for Front End Alignment of 1999 Ford F250 Super Duty

Published 10/04/2017

Question:

I have a 1999 Ford Superduty with 7.3L. have installed rear air bags to assist in towing a 10,000# travel trailer. The rear end is now sitting about 3inch higher than front of truck. If i install the supercoils and raise the front end by 2, will the supercoils cause a problem with front end alignment or geometry? The front suspension is stock.

Wow, even in the most inflated state, a suspension enhancement system (SES) should not raise the rear of your truck up 3 inches. So, before you try to balance it out with SuperCoils, I would review the installation of the SES to make sure that it is designed for your truck and was installed correctly.

If the SES is correct and you add the SuperCoils # SSC-31 to the front, it will increase your ride height by 2" and help level out the vehicle. Any time you add suspension components the geometry is changed, but this shouldn't cause an issue since adding suspension enhancement to the front and back is basically the equivalent of having a lift kit. You may need to get a ball mount with a different drop to accommodate the lift, but it shouldn't affect the ability of your vehicle to tow the trailer. Keep in mind that SuperSprings does not recommend DIY installation. SuperCoils should be installed by a qualified technician or installer.
