Complete 2-Inch Front / 3-Inch Rear Lowering Kit for Aluminum Steering Knuckles

Precision Ride Height • No Cutting • Correct Alignment • Rear Shocks Included

Lowering your late-model Chevrolet Tahoe or Suburban is one of the most impactful upgrades you can make—both visually and in terms of performance. The factory ride height on 2015–2018 GM SUVs is noticeably tall, leaving excess wheel gap and a higher center of gravity that not everyone finds appealing. If you're ready to achieve a cleaner stance, sharper handling, improved aerodynamics, and a more aggressive overall look, this 2-inch front / 3-inch rear complete lowering kit is the perfect choice.

And if your SUV is equipped with aluminum steering knuckles—the lightweight version used on specific trims between 2015–2018—this is the correct kit engineered precisely for your vehicle.

This is a bolt-on, remove-and-replace system that drops your Tahoe or Suburban evenly, maintains proper suspension geometry, and preserves daily-driver comfort while giving your SUV the modern stance it deserves.

Rear shocks #2000 are INCLUDED, along with everything needed for correct alignment and proper suspension function.

If your vehicle uses cast iron spindles instead, you’ll need this kit:

• Coil springs designed for a 3-inch rear drop

WHY THIS LOWERING KIT IS THE RIGHT CHOICE

Lowering an SUV is not just about appearance—although it transforms the stance instantly. It’s also about handling, comfort, and performance.

A properly engineered lowering kit like this one offers:

✔ Correct alignment after lowering

No guessing, no camber problems, no tire wear issues.

✔ Maintained ride comfort

You get a smoother, more controlled ride—not a harsh, bouncy one.

✔ Improved handling and stability

Lower center of gravity =

• Flatter cornering

• Sharper steering feel

• More confidence on the road

✔ Better aerodynamics

Less air drag at highway speeds and improved fuel efficiency.

✔ Perfect stance

Removes the factory “SUV rake” and gives you a clean 2/3 look—balanced, modern, and aggressive.

FRONT SUSPENSION DROP — 2 INCHES OF CONFIDENCE & CONTROL

The front of the 2015–2018 Tahoe/Suburban is tall from the factory—designed for towing, clearance, and family hauling. But when you’re building a street-focused SUV, that height works against you.

This kit lowers the front 2 inches using properly-engineered lowering control arms for aluminum knuckles. This:

• Reduces wheel gap

• Enhances aesthetic appeal

• Improves aerodynamic efficiency

• Provides a noticeably more composed road feel

Most importantly, the drop does NOT compromise steering geometry or suspension articulation. Everything installs with OEM-style fitment and predictable factory-level handling.

REAR SUSPENSION DROP — 3 INCHES OF REFINED STANCE

For the rear, this kit includes:

✔ Drop springs

✔ Corrected trailing arm brackets

✔ Extended sway-bar end links

✔ New rear shocks (#2000 included)

These components work together to produce:

• A true 3-inch drop

• Correct pinion angle

• Smooth suspension travel

• Proper sway bar operation

• No bottoming out

• OEM-quality control and stability

Your Tahoe/Suburban will sit level or slightly forward-raked depending on tire size—perfect for a street, cruiser, family, or lifted-wheel show build.

DOES NOT REQUIRE CUTTING OR WELDING

This is a remove-and-replace system—making it perfect for:

• Daily drivers

• Leased vehicles

• DIY installers

• Shops looking for quick turnaround

• Builders who want clean, reversible modifications

All components bolt directly into factory locations.

RIDE QUALITY — SMOOTHER THAN STOCK?

Most people assume lowering an SUV makes the ride harsher.

With this kit?   Not at all.
The ride becomes more composed, more controlled, and less floaty.

The factory suspension on a Tahoe/Suburban is soft and tall. When lowered correctly with properly-matched shocks and geometry, your SUV actually gains stability and control without sacrificing comfort.

Expect:

• Reduced body roll

• Sharper steering response

• Better high-speed confidence

• Less nose-dive under braking

• Improved feedback without harshness

This kit delivers the “luxury sport SUV” ride feel that GM should have offered from the factory.

BEST USE CASES — PERFECT FOR ANY STYLE OF BUILD

This kit is ideal for:

• Daily-driven family SUVs
• Show builds
• Street cruisers
• Performance-focused setups
• Big wheel builds (22”, 24”, 26”)
• Staggered wheel applications
• Stance/lowered luxury looks

If your goal is to combine style, performance, and comfort, this kit checks every box.
