Review FABTECH 3.5 Inch Uniball Uca Lift Kit Shocks Gmc Hd fits SIERRA K1155DL 2500 2020–2022

The **FABTECH 674866110823 K1155DL 3.5" UCA Lift Kit with Shocks** is a premium aftermarket suspension upgrade specifically engineered for the **2020 2022 GMC Sierra 2500 HD**, offering a seamless blend of performance, durability, and off-road capability. Designed to enhance ride height, articulation, and ground clearance, this lift kit features a **3.5-inch lift** that elevates the truck s suspension while maintaining a balanced, stable ride for both on-road comfort and off-road versatility. The kit includes **high-quality coilover shocks** with adjustable damping, allowing drivers to fine-tune stiffness and responsiveness to match their driving preferences whether prioritizing a smoother highway cruise or a firmer, more aggressive off-road stance. At the heart of this system is a **3.5-inch UCA (Upper Control Arm)**, which replaces the stock components to improve wheel alignment, reduce binding, and minimize excessive caster or camber changes, ensuring consistent tire wear and optimal handling. The shocks themselves are built with **durable, corrosion-resistant materials**, including reinforced internals and sealed bearings, to withstand harsh conditions, frequent use, and the demands of heavy-duty towing or off-road adventures. Whether tackling rocky trails, snow-covered roads, or simply achieving a more commanding presence on the highway, this lift kit delivers a noticeable improvement in ground clearance typically adding **3.5 inches to the truck s ride height** without compromising structural integrity or safety. Ideal for those seeking a **mid-range lift** that avoids the extreme adjustments of full suspension lifts while still providing noticeable benefits, the FABTECH K1155DL is a smart investment for truck enthusiasts who demand both functionality and style.

### **Pros and Cons of buying a Fabtech 674866110823 K1155DL 3.5" UCA Lift Kit Shocks for 2020-2022 GMC Sierra 2500**

1. **Increased Ground Clearance** The 3.5-inch lift provides noticeable extra height, which can improve off-road capability, especially for light trail use, snow tires, or avoiding low clearances on rough terrain.

2. **Improved Off-Road Performance** The lift kit is designed for better articulation and wheel travel, allowing the truck to handle uneven surfaces more effectively than stock suspension.

3. **Better Tire Fitment** Larger tires (up to 35" or so, depending on setup) can be installed without rubbing, giving better traction and a more aggressive stance.

4. **Durable Construction** Fabtech is a reputable brand known for quality components, including heavy-duty springs, shocks, and UCA (Upper Control Arm) upgrades that reduce binding and improve suspension movement.

5. **Compatibility with Other Mods** The lift kit works well with other aftermarket parts like leveling kits, coilovers, or lift springs, allowing for customization based on driving needs.

6. **Warranty Coverage** Fabtech typically offers a warranty (check the specific terms), providing some peace of mind against manufacturing defects.

7. **Easier Installation (Compared to Full Lift Kits)** While still requiring mechanical skill, this is a more straightforward lift kit than a full suspension swap, making it accessible for DIYers with basic tools.

---

1. **Not a Full Suspension Lift** This is a **shock/lift kit**, meaning it primarily affects ride height and shock performance but does not include full suspension components (like new springs or control arms in all cases). Some users may still experience binding or uneven ride height without additional modifications.

2. **Potential for Binding** If the truck is heavily modified (e.g., with large tires or heavy loads), the stock control arms or frame rails may still bind, leading to a rough ride or premature wear on other suspension parts.

3. **Ride Quality Sacrifices** A lifted truck typically has a firmer, less comfortable ride compared to stock. This kit does not include coilovers, so the ride may still feel stiff, especially on pavement.

4. **Cost of Additional Mods** To fully optimize the lift, you may need to invest in extra parts like **leveling links, extended control arms, or sway bar upgrades**, increasing the total cost.

5. **Potential for Drivetrain Stress** A lifted truck with larger tires can increase drivetrain strain, especially if the axle ratio is not ideal for the new tire size. This may lead to premature wear on axles, driveshafts, or transfer cases.

6. **Legal Restrictions** Some states or regions have height restrictions for trucks. Check local laws before installing a lift, as exceeding limits may result in fines or registration issues.

7. **Installation Complexity** While simpler than a full suspension swap, this kit still requires **disassembly of the stock shocks, mounting the new UCAs, and proper alignment**. Mistakes can lead to poor handling or damage.

The **Fabtech 674866110823 K1155DL 3.5" UCA Lift Kit** is a solid choice for **2020-2022 GMC Sierra 2500** owners looking to **improve off-road capability, fit larger tires, or enhance articulation** without a full suspension rebuild. It offers a **good balance of height gain and durability**, making it suitable for **light trail use, snow tires, or daily driving with minor off-road needs**.

However, it is **not a complete suspension upgrade**, so users should be prepared to **add leveling links, extended arms, or coilovers** if they want a smoother ride or full off-road performance. The trade-off between **height, durability, and ride comfort** depends on the user s priorities **heavy off-roading vs. daily comfort**.

---

- You want a **simple, effective lift** for **light trails, snow, or larger tires** without a full suspension swap.

- You plan to **supplement it with leveling links or extended control arms** for better articulation.

- You re comfortable with **basic suspension modifications** and have access to tools.

- You need **full off-road capability** (in which case a **full suspension lift** or **coilover setup** may be better).

- You want a **softer ride** (this kit does not include coilovers, so expect a firmer feel).

- You re unsure about installation **professional help may be needed** to avoid binding issues.

**Final Verdict:** This is a **good mid-range lift kit** for **practical off-road use**, but it s not a "set-and-forget" solution. Pair it with **proper tire selection and additional mods** (like leveling links) for the best results.
