To improve the ride and handling of your Grand Marquis/ Crown Vic/ Town Car, a few suspension modifications will have your Panther chassis able to cruise the highways in safety AND comfort.
Our Panthers respond very well to these mods, and the cost for parts is relatively low, considering the benefits.
The most obvious modification is to abandon the "stock" shock absorbers in favor of the High-Pressure, Gas-charged type - I chose KYB "Gas-A-Just" shocks all-around, due to having used them in the past, and they performed very well. Made in Poland.
Next on the list are the Control Arm Bushings -- "Stock" rubber bushings in both Upper & Lower Control Arms are replaced with Urethane Bushings, (I used Energy Suspension bushings) thus insuring that your wheel alignment adjustments will STAY where they're put for several years -- BIG savings in tire wear -- maintains precise steering -- excellent vehicle control.
Next come the Stabilizer Bars (Sway Bars), which need attention, but no replacement for the FRONT sway bar.
FRONT sway bar gets Greaseable Urethane Bushings (Energy Suspension) and Greaseable Sway Bar Links (MOOG).
The REAR sway bar gets replaced with an ADDCO 1" Rear Sway Bar, and greaseable Urethane bushings (Energy Suspension) -- Rear sway bar End Links are replaced with Energy Suspension end links with urethane bushings.
AFTER these mods are completed, be SURE to get a COMPUTERIZED WHEEL ALIGNMENT that gives you a Print-Out, so you can SEE that your alignment was done to specification. NO guesswork !!
Your Panther will no longer pitch, rock, and/or sway, and there will be no more big-car "float" at high speeds. Cornering will now be flat and smooth, without annoying "Body Roll". Your expensive tires will last longer, too !
These mods were done on The 95 MERC several years ago, and all have proven to be of great value, both in performance, comfort, and safety.
All parts mentioned above were purchased from RockAuto and Amazon.
