Review LIFTSUPPORTS Rear Pick Up Bed Crossmember Kit Select Chevrolet/gmc Model's

The **LiftSupport L183673RTS for 926-982 Rear Up Bed Crossmember Kit** is a meticulously engineered aftermarket solution designed exclusively for select Chevrolet and GMC full-size trucks equipped with the 926-982 rear up-bed crossmember configuration, spanning models from the late 1990s through the early 2000s. This kit is crafted to enhance the functionality, safety, and durability of your truck s bed area while accommodating a wide range of aftermarket applications, from heavy-duty tool storage to custom lift installations. Engineered with precision, the kit features a robust **galvanized steel construction**, ensuring resistance to corrosion and wear even in the harshest conditions, whether you re hauling construction materials, towing trailers, or navigating off-road terrain. The design prioritizes **easy installation**, with pre-drilled and aligned components that minimize the need for extensive modifications to your truck s existing frame or bed rails. This kit is particularly well-suited for owners looking to upgrade their truck s bed for **lift kit installations**, as it provides a secure, reinforced mounting point that distributes weight evenly, reducing stress on the frame and suspension. Whether you re integrating a **coilover lift**, **airbag lift**, or **leaf spring upgrade**, the L183673RTS ensures a stable foundation that maintains alignment and structural integrity. Additionally, the kit s compatibility with a variety of aftermarket accessories such as bed rails, tonneau covers, or cargo management systems makes it a versatile choice for customization. Built to meet or exceed OEM standards, this kit is backed by LiftSupport s reputation for quality, offering a reliable solution for truck enthusiasts who demand both performance and longevity. With its straightforward installation process and durable materials, the L183673RTS is an essential upgrade for anyone looking to maximize their truck s utility while preserving its structural soundness.

### **Pros and Cons of buying a Lift Support L183673RTS for 926-982 Rear Up Bed Crossmember Kit (Select Chevrolet/GMC)**

1. **Improved Lift Height and Stability** This kit is designed to enhance the lift height of your truck, allowing for larger tires and better ground clearance. The reinforced crossmember ensures stability, reducing sway and flex under heavy loads or aggressive driving.

2. **Compatibility with Aftermarket Lifts** If you plan to install an aftermarket lift kit (e.g., Fox, Bilstein, or other brands), this crossmember provides a solid foundation, preventing sagging or misalignment that can occur with stock components.

3. **Durability and Reinforcement** The kit is constructed from high-strength materials (likely steel or heavy-duty aluminum) to handle the increased stress from lifted suspensions, heavy-duty towing, or off-road use.

4. **Easier Installation** Compared to fabricating a custom crossmember, this kit is pre-engineered for your specific truck model (926-982 chassis), reducing the risk of errors and simplifying the build process.

5. **Potential for Better Handling** A properly installed lift support kit can improve suspension geometry, leading to more predictable handling, especially when carrying heavy loads or driving off-road.

6. **Future-Proofing** If you plan to upgrade your suspension (e.g., adding shocks, sway bars, or coilovers later), this kit provides a solid base for those modifications.

7. **Warranty and Support** Reputable manufacturers like Lift Support offer warranties and customer support, which can be valuable if issues arise during installation or use.

1. **Cost** This is not a cheap modification. Depending on labor and additional required parts (e.g., new springs, shocks, or alignment), the total cost can be significant, especially if you re not already running a lifted setup.

2. **Installation Complexity** While the kit is designed for easier installation, it still requires mechanical skill, proper tools, and possibly professional help. Improper installation can lead to alignment issues, drivetrain damage, or suspension failure.

3. **Potential for Alignment Issues** Lifting a truck can throw off the alignment, leading to uneven tire wear or handling problems. You may need to get an alignment after installation, which adds to the cost.

4. **Drivetrain Stress** A lifted truck with larger tires can cause the driveshaft to angle improperly, leading to vibration, drivetrain wear, or even failure over time. You may need to install a driveshaft support or angle kit to mitigate this.

5. **Resale Value Impact** While lifted trucks are popular in certain markets (e.g., off-road or custom builds), they may not hold their value as well as stock or mildly modified trucks. Buyers often prefer lower lifts or stock height for daily driving.

6. **Potential for Modification Conflicts** If you have other aftermarket modifications (e.g., a lifted cab, custom fenders, or a long-bed conversion), you ll need to ensure compatibility with this kit to avoid clearance issues.

7. **Maintenance Considerations** A lifted truck may require more frequent maintenance, such as checking suspension components, wheel bearings, and drivetrain angles, due to the increased stress on these parts.

### **Conclusion and Recommendation**

The **Lift Support L183673RTS crossmember kit** is a solid choice if you re looking to **legally and safely lift your 926-982 chassis Chevrolet/GMC truck** while maintaining stability and compatibility with aftermarket lifts. It s particularly useful if you plan to run larger tires, improve off-road capability, or install a suspension upgrade.

- Proper suspension components (shocks, springs, sway bars).

- Drivetrain adjustments (driveshaft angle kit, if needed).

- Wheel and tire selection (appropriate size and load rating).

- Professional installation or thorough DIY preparation to avoid costly mistakes.

**If you re a first-time lifter or unsure about the process**, consider consulting with a suspension specialist or lift shop to ensure everything is installed correctly. Additionally, if your primary use is **daily driving**, a lower lift (e.g., 2-3 inches) may be more practical than a full off-road setup.

- **Buy it if:** You re committed to lifting your truck responsibly, have a plan for the full suspension upgrade, and are prepared for the associated costs and maintenance.

- **Avoid it if:** You re unsure about the installation process, don t want to deal with potential alignment or drivetrain issues, or prefer to keep your truck stock-height for convenience.

- **Alternative Consideration:** If you re not ready for a full lift, look into **adjustable suspension systems** or **lower-cost lift kits** that don t require a crossmember replacement.

For the best results, **research thoroughly, plan your build step-by-step, and prioritize safety over aesthetics**. A well-executed lift can greatly enhance your truck s performance, but a poorly done one can lead to safety hazards and expensive repairs.
