Detroit Speed has recently brought its high-end suspension and chassis engineering to the S-10 / S-15 / Sonoma platform, delivering bolt-in, performance-oriented upgrades spanning front and rear systems, steering, and drivetrain components.

If you’re building a small truck that handles like a sports car - or simply want serious improvements over stock - this guide walks you through how to evaluate Detroit Speed’s S-10 offerings, choose the right kit for your goals, and understand which parts you might want to layer in over time.

What Makes Detroit Speed’s S-10 Line Stand Out?

Before you pick a kit, you should understand why Detroit Speed’s approach is compelling:

1. Full-system design, not piecemeal parts: Detroit Speed’s Speed Kits are designed as integrated systems (front, rear) that balance geometry, adjustability, and ride quality.  

2. Bolt-in with minimal fabrication: Many of their kits, especially the Front Speed Kits, are engineered to install with basic tools and minimal or no cutting, welding, or chassis modification.  

3. Adjustability & tuning flexibility: Ride height, damping, and alignment features are easily adjustable—this allows you to dial in stance vs performance. For example, the Front Speed Kit 1 includes double adjustable coilovers with ~2.5” of drop capability.  

4. Matching rear solutions: Detroit Speed supplements its front kits with rear systems; drop leaf springs and QuadraLink 4 link conversion options. All systems are tested and tuned to ensure balanced handling.

5. Parts-level modularity: You don’t always have to buy a whole kit all at once. Many components (control arms, drop kits, rear arms, bushings, sway bars) are available separately so you can build in phases.  

Build Your Kit

Step 1: Define Your Driving Goals

Ask yourself:

• How much drop or height adjustability do I want? A mild 2/3 or aggressive 4/5?
• What power level will the engine be making? A well-tuned rear suspension greatly improves the performance of high horsepower trucks.
• What’s my budget and timeline?

If you’re aiming for a street driven, comfortable ride with stock driveline; a milder speed kit or building in stages is recommended.

When planning for V8 swaps, aggressive cornering, or track use; opt for the Quadralink system tuned for these applications.

Step 2: Front, Rear, or Both?

Front and Rear kits are available in multiple configurations to fit the goals of your build. Detroit Speed offers 3 levels of Front and Rear Speed Kits for your S-10.  

• Front Speed Kit: Lowered ride height, improved handling and steering, but you’ll need something in the rear to match.
• Rear Speed Kit: Lowered leaf springs, improved handling and ride quality. Designed to match the lowering of the front suspension.
• Quadralink Kit: 4 link conversion with coilovers, C notch and optional 9” rear axle vastly improves performance and reliability.

Combining the front and rear suspension kits to complete a full vehicle build leverages the expertise of Detroit Speed in providing a well-balanced handling kit for your truck.

• Complete Vehicle Speed kit (front + rear): Provides great handling experience for street performance vehicles.
• Front Speed Kit + Quadralink Conversion: Step up the performance level and reliability of your truck to transform it into a extremely capable street or track use vehicle.

Step 3: Understand Adjustability & Features

Kits offer varying levels of adjustability to fine tune performance for your build.

• Drop Range and Adjustability: Drop Spindles and Leaf Springs provide a static drop that is not adjustable. Front and Rear Coilovers allow for ride height adjustment.
• Double Adjustable Shocks: All Detroit Speed S10 kits include QA1 double adjustable shocks to fine tune the ride quality and performance of your truck. Baseline settings are provided to give great performance out of the box.
• Rear Geometry Adjustability: Featured in the Quadralink system, instant center and roll centers geometry is adjustable to dial in the track performance of your truck. Tuning guides are provided with the kit.

Step 4: Rear Suspension Options & Upgrades

Once your front is sorted, don’t neglect the rear. Options include:

• Leaf spring drop kits
• Upgraded trailing arms
• Full multi-link or torque-arm style systems
• Matching shock and damping setups
• Bushings, shackles, mounts

Detroit Speed has Rear Speed Kits and options to upgrade rear control arms, trailing arms, and housings.  

Step 5: Phase Your Build (If Not All at Once)

You might prefer to upgrade in stages. That’s fine, but to ensure each stage is compatible with future upgrades:

1. Start with Front Speed Kit
2. Add rear drop / arms / shocks
3. Add sway bars, fine-tune alignment, geometry
4. Go further with chassis stiffeners, subframe connectors, etc.

Detroit Speed’s modular parts inventory and kit compatibility make that possible.

Installation & Setup Tips

• Always start with clean mounting surfaces, checking for rust, deformation, or damage.
• Follow recommended torque specs during install.
• When installing coilovers or adjustable parts, set everything to a baseline setting and then fine-tune gradually.
• After installing rear suspension, check pinion angle, driveshaft clearance, and rear alignment geometry.

Final Thoughts & Recommendations

The S10 platform has long been popular in the custom community, but they often lack the ride and handling needed for a refined build. Detroit Speed’s S-10 product line is one of the strongest “drop-in” paths on the market. Their reputation in older GM and muscle car markets carries over into this platform, giving you engineering maturity, compatibility, and modular upgrade paths.

With options to fit all build goals and budgets, look to Detroit Speed for your S10 handling needs.
