2015 F150 F150Lifts BOSS Coilovers Review

For the final chapter in our 2015 F150 coilover reviews series, we have the 2014-2015 F150 F150Lifts BOSS Coilovers. F150Lift's coilovers are designed to provide a full inch of extra ride height over the Fox 2.0s while being less expensive than 2.5 coilover kits, including the ICON 2.5s that were on our truck. With that in mind, what kind of ride do they provide both on and off the road on the 2015 F150s? We were pretty determined to find out, so we took a quick drive up to Lake Pleasant, Arizona, to thrash our 2015 F150 3.5L EcoBoost Project Truck around with the F150Lifts BOSS coilovers installed. The coilovers worked as advertised, with a great, 3" of front lift that made our truck look a heck of a lot better with its 3" rear block that came paired with a street ride that was a hint smoother and more refined than the Fox 2.0s. As expected, the BOSS coilovers didn't perform as well off-road as the ICONs, but they were more than adequate below 35mph on light to medium trails.

2015 F150Lifts BOSS Coilovers Pros:

• Flawless Street Ride: the street ride quality of the BOSS coilovers is just ridiculously good. Smoother than the Fox 2.0s while at the same time soaking up bumps and bad roads with less body roll and wallowing around.
• 3" of Extra Height: the 0-3" range of adjustment is a full inch taller than stock and a good third taller than highest settings of the ICON 2.5s, which gives some extra room for larger tires and more ground clearance.
• Improved Off-Road Performance than the Fox 2.0s: the F150Lifts coilovers do a bit better than the Fox system off-road, handling higher speeds and more aggressive trails without much fuss. The extra potential ground clearance also helps.

F150Lifts Coilovers Cons:

• Fairly Stiff Off-Road Ride: while better than the Fox 2.0s in light off-road conditions, the F150Lifts BOSS Coilovers just don't quite absorb really violent impacts in the same way that the ICON 2.5 Coilovers do.
• Not great for high-speed trail runs: whether it was fade or just their valving, the BOSS Coilovers didn't provide the same performance at 35mph on a moderate trail as the ICONs. Granted, we're stupid enough to drive that fast, which means we should be using a 2.5 coilover, anyway.
• UCA Highly Recommended: with 3" of ride height throwing off the stock UCA angles, even a moderate amount of articulation can either cause the UCA to hit the coilovers' springs or cause some binding in the factory arm's ball joint fairly quickly. For any decent off-road application at the full 3" of height, we'd strongly recommend getting yourself an aftermarket uniball UCA along with these coilovers.

Overall, the F150Lifts front coilovers make for a great upgrade over stock, and while they can't quite match the brutal off-road performance of 2.5 coilovers, they have an excellent street ride and just enough extra off-road oomph to get the job done on the vast majority of truck's out their. Their 3" ride height capability also gives your 2015 F150 the potential to get an aggressive, awesome stance, especially when its combined with a larger rear block. More ride height also means extra clearance for larger tires, which means more ground clearance, which is never a bad thing.
