Coil springs are the way to go
Ford fans probably were left wondering when they discovered that the F-150 Raptor will not have an independent rear suspension (IRS). It did the transition from coil springs in the back to leaf springs, which led many customers to think that IRS would be easy. The new Raptor has the same solid-axle design as the old model. We’d be remiss if we didn’t mention the fact that this is a disappointing Ford product for many Ford purists. Ram TRX Uses a very similar setup. Both share a five-link configuration with Blue Oval offering sporting extra long trailing arms, Panhard rod and 24-inch coil springs. They are only.378 inches longer that those on the TRX, if you want to keep score. Many would argue that the F-150 Raptor would suffer from a rigid rear-axle, but that is not true. The new rear-suspension design not only offers more towing and payload capability, but it also provides more articulation over obstacles and reduced friction.
It is lighter than any leaf spring setup. Ford’s new suspension configuration, when fitted with 35-inch tires, allows for 15 inches of rear suspension travel. This may sound confusing, but it’s actually 25 percent more than the F-150 Raptor and two inches more than what the Ram TRX has. The best thing about coil springs is their superior ride quality. This configuration is very likely to be available on other F-150 models in a not too distant future.
