Belltech Lowering Kits
A Belltech lowering kit pairs matched coil springs or drop spindles with Street Performance shocks or struts to lower a truck or SUV 1 to 6 inches front and rear, depending on the vehicle and kit. Belltech sells model-specific kits for the Ford F-150, Ram 1500, Chevy Silverado, S10, Tahoe/Suburban and classic C10 trucks.

Belltech lowering kit series
Belltech's current lineup for pickups and SUVs is built around the Street Performance (SP) shock and strut package: a 55mm twin-tube shock with digressive valving, paired with vehicle-specific lowering coil springs or struts. It is the line used on the current Ford F-150, Ram 1500 and Silverado/Sierra 1500 kits.
| Series | Best for | Typical drop | What's included |
|---|---|---|---|
| Street Performance (SP) | 2004-and-newer trucks and SUVs still on coil springs or struts | Front 0"-5.5", rear 3"-6.5" (varies by kit) | 55mm twin-tube shocks or struts, lowering springs, hardware |
| Nitro Drop II (ND2) | Classic and 1980s-90s trucks chasing an adjustable ride | Front 2"-4", rear 4"-6" | Double-adjustable ND2 shocks, lowering coils or spindles |
| Complete/Deluxe lowering kit | C10 and S10 owners after the deepest stock-frame drop | Front up to 4", rear up to 6" | Drop spindles, rear axle flip kit, coils, Grade 8 hardware |
Street Performance suits a daily-driven modern truck that still needs to ride comfortably. Nitro Drop II or a complete kit fits an older truck build chasing the lowest stance the chassis allows.
Which trucks Belltech covers
Belltech publishes a kit per vehicle rather than one universal part. Beyond the F-150, Ram 1500 and Silverado/Sierra, verified current and classic-truck kits cover the Chevy S10, Tahoe/Suburban/Yukon and the classic C10; see the fitment table below for the specific part numbers and drop ranges we verified on Belltech's own product pages.
Several SP kits for trucks with factory Autoride or MagneRide dampers are not compatible with that electronic ride-height system; Belltech sells separate part numbers for those trims, so match the kit to your exact option package before ordering.
Belltech vs other lowering kit brands
Eibach's Pro-Truck line (see our Eibach lowering kit page) is the closest direct competitor for coil-spring trucks, using a springs-only approach rather than Belltech's matched shock-and-spring packages. McGaughys and Rough Country both sell drop spindle and axle flip kits that overlap with Belltech's deepest classic-truck drops, but neither bundles a sized shock into every kit the way Belltech's SP line does.
The practical difference for most buyers: a Belltech kit arrives with shocks, springs and hardware sized for one specific drop, so there is less guesswork than building a lowering setup from separate spring and shock purchases.
Installation and adjustment notes
Any drop spindle or axle flip kit changes suspension geometry, so an alignment is required after install, and Belltech's instructions call for re-torquing suspension hardware after a short break-in drive. For a plain-language rundown of the labor involved, see our lowering kit installation and cost guide.
On kits with height-adjustable Street Performance struts, ride height is set at the lower spring perch before the final alignment, not by over-extending the shock. Do not exceed the drop range listed for your specific part number; going lower than a kit was designed for shortens CV joint and driveshaft angle life.
FAQ
What comes in a Belltech lowering kit?
Most current Belltech truck and SUV kits are complete: matched lowering coil springs or struts, Street Performance shocks sized for the new ride height, and the Grade 8 hardware needed to install them. Classic-truck kits can add drop spindles and a rear axle flip kit to reach a deeper drop.
Will a Belltech kit void my factory warranty?
Belltech does not publish warranty terms that address factory vehicle coverage. Suspension modifications can affect a manufacturer's powertrain or ride-control warranty depending on the issue, so check with your dealer first.
Do I need an alignment after installing a Belltech kit?
Yes. Lowering the ride height changes camber, caster and toe, so an alignment after install is standard practice on every Belltech kit covered here, whether it uses springs, spindles or struts.
What is the difference between Street Performance and Nitro Drop II kits?
Street Performance (SP) is Belltech's current shock and strut package for 2004-and-newer trucks and SUVs. Nitro Drop II (ND2) is a double-adjustable shock used mostly on older platforms like the classic C10 and S10, often paired with drop spindles for a bigger drop than an SP kit alone provides.
Can I use a Belltech lowering kit on a truck with Autoride or MagneRide?
Not with a standard SP kit. Belltech's part numbers for trucks like the GM Tahoe/Yukon and Silverado/Sierra specify fitment for vehicles without Autoride or MagneRide, and a separate kit is usually needed for trims equipped with that electronic damping.
How much does a Belltech lowering kit cost?
Pricing is kit-specific. Belltech listed its Silverado/Sierra 1500 Street Performance kit (1018SP) at $961 at the time of writing; classic-truck kits with drop spindles and an axle flip run higher. Check the current price for your exact part number before buying.
