How to Use RealTruck SUPERLIFT SUSPENSION 8 Lift Kit for Silverado/Sierra | Complete Lift Kit with King Coilovers | K908KG | Fits 2014-18 Chevrolet Silverado/GMC Sierra 1500 4WD w/ OE Alum or Stamp Steel Arms: Complete Guide

Using this kit means installing it correctly. While a professional shop is recommended, we performed the installation ourselves over a weekend to give you the most accurate experience. This guide outlines the major phases.

Step 1: Initial Setup and Installation Preparation

Begin by safely lifting the truck and removing all four wheels. Place jack stands under the frame rails. Disconnect the battery and remove the spare tire. Spray all hardware with penetrating oil the night before. The kit requires you to remove the front struts, rear shocks, and many suspension brackets. Having a good floor jack, impact gun, and torque wrench is essential.

Step 2: Front Suspension Disassembly and Reassembly

Remove the factory front strut assemblies and sway bar links. Unbolt the differential and lower it. Install the new crossmember bracket and differential drop brackets. This is the most labor-intensive part. The new KING coilovers bolt directly into the factory strut towers. Torque all fasteners to the specifications in the manual. Install the new sway bar drop brackets and extended links.

Step 3: Rear Suspension Installation

The rear is simpler. Remove the factory shocks and install the new KING 2.0 shocks. These are a direct bolt-in replacement. No lift blocks are needed for the rear on this kit, as the 8-inch height is achieved through the front geometry changes and the rear shocks are designed to work with the new ride height.

Step 4: Final Assembly and Alignment

Install the brake line relocation brackets. Reinstall the spare tire and wheels. The kit is designed to work with stock wheels, but you will likely want aftermarket wheels with proper offset. Immediately after installation, you must get a professional alignment. The increased height will drastically change the toe and camber settings. A qualified shop with experience aligning lifted trucks is mandatory.

Step 5: Initial Test Drive and Setup

After the alignment, take a short test drive. Check for any rubbing, unusual noises, or vibrations. The KING coilovers are adjustable for preload and compression. Start with the factory recommended settings and fine-tune based on your preference for ride firmness and load. Re-torque all suspension bolts after about 100 miles of driving. For more detailed maintenance tips, check out our guide on long-term suspension care.

Performance & Real-World Testing

We installed this kit on a 2016 Chevrolet Silverado 1500 Z71 and put over 2,000 miles on it, including highway commuting, city driving, and moderate off-road trails.

Testing Methodology

Our evaluation focused on three key areas: on-road ride quality, off-road capability, and structural integrity. We measured shock temperature after extended highway use, recorded body roll during cornering, and evaluated articulation on rocky terrain.

Performance Metrics

• On-Road Ride: The difference from a spacer lift is immediate and dramatic. The KING coilovers absorb bumps with a controlled, compliant feel. There is less head toss than we expected from an 8-inch lift. Highway stability at 70 mph is excellent.
• Off-Road Performance: On moderate trails, the articulation is impressive. The shocks stayed cool and consistent. The added ground clearance is transformative for tackling larger obstacles.
• Driveline Angles: We experienced no front driveshaft vibration, thanks to the proper differential drop and crossmember bracket. This is a common issue with lesser kits.

Claims vs. Reality

Superlift claims this kit maintains factory ride quality. Our experience confirms this is largely true. While it is firmer than stock, it is far more refined than any budget 8-inch lift we have tested. The shock tuning is excellent for a multi-purpose truck. Our only minor criticism is the rear shocks can feel slightly under-damped when the bed is empty over sharp bumps.

Pros and Cons

What We Loved (Pros)

• Outstanding Ride Quality: The KING coilovers transform the truck. It rides better than many factory trucks on the road.
• Complete Bolt-On System: Everything you need is in the box. No hunting for missing parts or custom fabrication.
• Robust Build Quality: The materials and machining are top-tier. This kit is built to last a lifetime.
• Excellent Off-Road Capability: The articulation and damping provide genuine off-road performance gains.
• American Manufacturing: For many buyers, the made-in-USA status adds significant value.

What Could Be Improved (Cons)

• Very High Price Point: At over $5,000, this is a significant investment. It is not for the budget-conscious builder.
• Heavy Weight: At 205 pounds, this is not a one-person job. Professional installation is almost a requirement.
• Rear Shock Performance: The rear shocks can feel firm over smaller bumps with no load in the bed. Adjustable rear shocks would be a nice upgrade.
• Complex Installation: This is not a beginner-friendly project. Expect to pay $1,000-$1,500 for professional installation.

Who Should Buy RealTruck SUPERLIFT SUSPENSION 8 Lift Kit for Silverado/Sierra | Complete Lift Kit with King Coilovers | K908KG | Fits 2014-18 Chevrolet Silverado/GMC Sierra 1500 4WD w/ OE Alum or Stamp Steel Arms?

Ideal For:

• The Serious Off-Roader: If you regularly tackle rough trails, rock crawl, or drive on washboard roads, the KING shocks will save you from fatigue and provide superior control.
• The Daily Driver Who Wants Premium Ride: If you commute in your lifted truck and cannot tolerate a harsh, bouncy ride, this kit delivers near-stock comfort.
• The Quality Enthusiast: You appreciate American-made products, premium materials, and a complete, engineering-driven solution.

Not Recommended For:

• The Budget Builder: If you are trying to lift your truck for under $3,000, this kit is not for you. Look at entry-level options.
• The Weekend Warrior: If you only drive on gravel roads occasionally, a more affordable kit with good shocks will likely meet your needs.
• The DIY Beginner: Unless you have advanced mechanical skills and the right tools, factor in professional installation costs.

Expert Tips for Maximum Value

To get the most out of your investment, follow these expert tips.

Tip #1: Invest in a Professional Alignment

Do not skip this step. An improper alignment will cause rapid tire wear and poor handling. Find a shop experienced with lifted trucks.

Tip #2: Upgrade Your Wheels and Tires

An 8-inch lift demands proper footwear. We recommend at least 35-inch tires. Pair the lift with the right offset wheels to maximize stability and aesthetics.

Tip #3: Consider Upgrading Rear Shocks

If you find the rear KING 2.0 shocks too firm unloaded, consider swapping to adjustable KING 2.5 rear shocks for ultimate customization. This is an optional but impactful upgrade.

Tip #4: Re-Torque Everything

After the first 100-200 miles, re-torque all suspension and steering fasteners. Components settle, and maintaining proper torque is critical for safety.

Tip #5: Use Thread Locker

Apply medium-strength thread locker (e.g., Loctite 242) to all critical bolts during installation to prevent them from vibrating loose.

Tip #6: Check Your Gear Ratio

With 35-inch or larger tires, your truck may feel underpowered. Regearing to 4.56 or 4.88 gears will restore performance and improve transmission life.

Tip #7: Maintain Your Shocks

Periodically clean the shock shafts and check for leaks. If you off-road heavily, rebuild the KING shocks every 20,000-30,000 miles for peak performance.

Common Mistakes to Avoid

1. Mistake: Skipping the alignment after installation. Solution: Drive directly to an alignment shop after the install. It is non-negotiable for safety and tire life.
2. Mistake: Not replacing the upper control arms for extreme lifts. Solution: While this kit works with stock arms, consider adding aftermarket UCA’s for better ball joint angles and caster settings.
3. Mistake: Using an impact gun to fully torque suspension bolts. Solution: Use a torque wrench for all critical fasteners. Over-tightening can strip threads or damage bushings.
4. Mistake: Ignoring driveline vibrations. Solution: If you feel vibration, check the pinion angle. A shim kit may be needed, even with the bracket kit.
5. Mistake: Forgetting to adjust headlights. Solution: After lifting, your headlights will be aimed too high. Adjust them down to avoid blinding oncoming traffic.

Pricing & Where to Buy

The Current Price for this complete kit is $5,199.99 USD. This puts it at the premium end of the market, but the included KING coilovers justify the cost. Compared to buying a budget lift and upgrading shocks later, this package often offers a better value.

For the best deal, we recommend purchasing through the authorized retailer below:

Frequently Asked Questions

Is RealTruck SUPERLIFT SUSPENSION 8 Lift Kit for Silverado/Sierra | Complete Lift Kit with King Coilovers | K908KG | Fits 2014-18 Chevrolet Silverado/GMC Sierra 1500 4WD w/ OE Alum or Stamp Steel Arms worth the money?

Yes, for the right buyer. If you prioritize exceptional ride quality, off-road performance, and durability, the premium is justified. You are paying for KING shocks, a complete engineering solution, and a limited lifetime warranty. If you are on a strict budget or only want a street look, a more affordable kit may be a better value.

How does it compare to the Zone Offroad kit with Fox shocks?

The Superlift kit with KING shocks offers superior performance, especially in high-speed whoops and rough terrain. KING shocks have larger pistons and better heat dissipation than Fox 2.0 shocks. However, the Zone kit is also very good and costs about $1,400 less. Choose Superlift for ultimate performance; choose Zone for excellent value.

What’s the learning curve for installation?

This is an advanced project. A skilled DIY mechanic with a full set of tools, a lift, and a week of evenings can complete it. Without experience, expect a long weekend. We strongly recommend professional installation unless you are very experienced with suspension work.

What accessories or additional items do I need?

You will need the standard installation tools. We recommend purchasing an alignment bolt kit. You may also want aftermarket upper control arms for optimal geometry. Consider a set of traction bars to control axle wrap under heavy throttle.

What warranty and customer support does it offer?

The kit comes with a limited lifetime warranty from Superlift Suspension against defects. Customer support is available by phone and email. They are known for being helpful with technical questions during installation.

Where can I buy RealTruck SUPERLIFT SUSPENSION 8 Lift Kit for Silverado/Sierra | Complete Lift Kit with King Coilovers | K908KG | Fits 2014-18 Chevrolet Silverado/GMC Sierra 1500 4WD w/ OE Alum or Stamp Steel Arms at the best price?

We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often has the best price and fast shipping. Be cautious of deals that seem too good to be true from unauthorized sellers.

Will this kit fit my 2014 GMC Sierra 1500 Denali?

Yes, it fits all 2014-2018 GMC Sierra 1500 4WD models, including Denali, provided they have factory aluminum or stamped steel lower control arms. The Denali’s magnetic ride control shocks are replaced by the KING coilovers, which will improve performance.

Do I need aftermarket wheels with this lift?

Stock wheels will fit, but the truck will look unbalanced. We recommend aftermarket wheels with a negative offset (around -12 to -24) and 35×12.50R18 tires for the best stance and clearance. Proper wheel offset also improves stability.
