If you’re chasing sharper handling, smoother rides, or the clearance to run wider wheels and meatier tires, an aftermarket suspension upgrade is the way to get it done. Whether you're building for the strip, the trail, or the daily grind, suspension is where performance and control come together. It’s what keeps your tires planted, your stance dialed, and your mods working like they should.
At Lethal Performance, we carry a full lineup of aftermarket suspension kits and components for serious setups: coilovers, lift kits, lowering springs, sway bars, control arms, and complete systems from proven brands like BMR, Icon, Eibach, RPG Off‑Road, and more. From F-150s and Mustangs to Broncos and Explorer STs, our suspension upgrades are ready to match your performance goals.
Suspension upgrades change how your vehicle handles everything: throttle, corners, bumps, and weight transfer. Whether you're building for the street, the strip, or the trail, dialing in the right suspension setup means better control, more confidence, and the clearance (or drop) your mods demand. Here's what to focus on based on your build.
If you're after daily drivability with a sharper edge, start with lowering springs or adjustable coilovers. They'll drop your center of gravity without killing ride comfort. Pair them with upgraded sway bars and control arms to cut down on body roll and tighten up your cornering. Add polyurethane bushings and chassis bracing for a planted, responsive feel, especially if you're packing more horsepower than stock.
Getting that power to the pavement means controlling weight transfer. Drag-focused suspension upgrades like adjustable shocks, vertical links, cradle lockouts, and heavy-duty control arms help reduce wheel hop and keep your rear tires hooked under launch. A properly set rear suspension makes all the difference when you’re chasing 60-foots and trap speeds.
For trail use, overlanding, or desert ripping, suspension upgrades are about articulation and durability. Look for long-travel coilovers, heavy-duty upper control arms (UCAs), lift kits, and beefed-up dampers. Suspension kits from brands like RPG, Icon, or Fox let you clear bigger tires, smooth out rocky terrain, and take full advantage of your 4x4’s potential without bottoming out or blowing seals.
If you're doing a little bit of everything, go modular. A set of adjustable coilovers gives you control over ride height and damping, while upgraded end links, sway bars, and bushings help balance ride quality and responsiveness. These upgrades let you fine-tune your ride whether you're hitting weekend autocross events or hauling the family during the week.
No matter what you drive—or what you're building it for - Lethal Performance has the suspension kits and upgrades to match. Each part is tuned to the exact Ford platform it’s made for - fitment, geometry, and all.

From 5.0L V8s to Raptor builds, our F-150 suspension selection includes lift kits, leveling systems, and multi-stage coilovers from names like Icon, RPG Off‑Road, and Ford Performance. Whether you're chasing off-road flex or dialed-in stance, there’s a kit here with your name on it.
If you’re crawling rocks or bombing through sand, your Bronco’s suspension has to keep up.

Brands like Fox, BDS, and Bilstein help you get clearance, articulation, and serious trail confidence.
Lower it, tighten it, and make it corner like a real performance SUV. Our Explorer ST suspension upgrades include lowering springs, sway bars, end links, and full handling kits that’ll keep the body roll in check and the grin on your face.

Got questions about upgrading your suspension? Whether you're planning your first mod or fine-tuning a serious build, these answers will help you make the right moves under the chassis.
Yes, any time you change your vehicle’s ride height or suspension geometry, an alignment is a must. It keeps your tires wearing evenly and ensures your handling stays sharp instead of unpredictable.
Not always. Some kits are tuned for comfort, others for performance. Coilovers and upgraded shocks often give you more control over damping and ride stiffness, so you can firm things up for track days or dial them back for daily cruising.
Depending on your setup, yes. Going lower? Consider shorter end links or adjustable control arms. Lifting for off-road? You’ll want extended brake lines or diff drops to keep geometry in check.
