Understanding Your 2017 GMC Sierra Lift Kit Needs
Selecting the ideal 2017 GMC Sierra lift kit begins with a clear vision of your truck's intended use and desired aesthetic. Whether you aim to fit larger tires for improved off-road traction, gain ground clearance for challenging terrain, or simply achieve a more aggressive stance, the foundational purpose drives your choice.
- Define primary use: off-road, aesthetics, or towing.
- Determine desired lift height: 2-6 inches is common.
- Consider tire size compatibility.
- Budget impacts kit complexity and brand.
For the 2017 GMC Sierra, which falls within the fourth generation, lift kits are designed to alter suspension geometry, thereby raising the vehicle's body and frame. This modification not only changes the truck's profile but also impacts its handling characteristics. It is imperative to acknowledge that different lift types offer distinct advantages and require varying installation complexities.
Suspension vs. Body Lift Kits
Suspension lift kits are the most comprehensive, replacing or modifying components like control arms, shocks, springs, and potentially subframes. These kits generally provide more suspension travel and better off-road articulation. They are the preferred choice for serious off-roading and offer a superior ride quality, comparable to stock or even improved.
Body lift kits, on the other hand, are simpler and more budget-friendly. They use spacers to lift the truck's body away from the frame, allowing for larger tires without altering suspension geometry. While less expensive and easier to install, they do not increase suspension travel and can sometimes lead to minor alignment issues or a less integrated feel.
This mechanism is critical for achieving the desired outcome without compromising drivability.
Key Components and Their Functions
A typical suspension lift kit for your 2017 Sierra will include several vital components. Extended shocks and struts are essential for accommodating the increased suspension travel. New coil springs or torsion bar keys (depending on the front suspension design) are used to achieve the lift height. For the rear, lift blocks or new leaf springs are common.
Additionally, differential drop brackets might be included in higher lift kits (4 inches and above) to correct CV joint angles, preventing premature wear. Extended brake lines ensure proper fluid flow without binding. Sway bar links are often lengthened to maintain their functionality. Understanding these components is fundamental.
This detailed understanding is the first step.
Evaluating Lift Kit Factors for Your Sierra
What to Consider Before Buying
When evaluating lift kits for your 2017 GMC Sierra, several critical factors dictate the best choice for your specific needs. Beyond the brand name, consider the material quality, the specific lift height offered, and the intended purpose. For example, a 6-inch lift kit offers substantial clearance but may require more extensive modifications than a 3-inch kit.
Lift Height and Tire Clearance
The most common lift heights for the 2017 Sierra range from 2 to 6 inches. A 2-3 inch lift is often sufficient to fit 33-inch tires, providing a noticeable improvement in stance and moderate off-road capability. A 4-6 inch lift typically allows for 35-inch or larger tires, significantly enhancing off-road performance and visual appeal.
Ensure the kit you choose is compatible with the tire sizes you plan to run. Manufacturers usually specify the maximum tire size and wheel offset recommended for their kits. Running tires that are too large without adequate lift can lead to rubbing on fenders, control arms, or the frame, especially during turns or suspension compression.
The maximum tire size you can fit is a primary consideration.
Ride Quality and Handling
While lift kits alter suspension, many are engineered to maintain or even improve ride quality. Premium kits often use high-quality shocks (like Fox, Bilstein, or Rancho) that are tuned for both on-road comfort and off-road performance. Cheaper kits might compromise ride comfort, resulting in a stiffer or bouncier experience.
A well-designed suspension lift kit for your 2017 GMC Sierra will address critical alignment angles. This includes maintaining proper caster and camber, ensuring your truck steers straight and tires wear evenly. Kits that include components to correct differential angles and steering geometry are essential for predictable handling.
A suspension system designed for performance is never an afterthought.
Durability and Material Quality
The materials used in a lift kit directly impact its longevity and resistance to the elements. Look for kits constructed from high-strength steel, often with durable powder coatings to prevent rust and corrosion. Control arms should feature robust bushings or ball joints designed for the increased stress of lifted suspension.
Our analysis indicates that kits from reputable manufacturers often use forged or billet aluminum components for strength and weight reduction, particularly in upper control arms or steering components. These are more resistant to bending and wear than stamped steel parts. Such precision is paramount for long-term reliability.
Inspect the quality of welds on steel components; clean, consistent welds indicate a higher standard of manufacturing. If you're unsure about local expertise, searching for 'lift kit installers near me' can help find qualified professionals.
Top Picks and Where to Buy Your 2017 Sierra Lift Kit
Recommended Lift Kits for Your 2017 GMC Sierra
Choosing a lift kit can be daunting given the array of options. Based on widespread owner satisfaction, durability, and performance, certain brands consistently stand out for the 2017 GMC Sierra. These kits offer a balance of capability, ride quality, and value.
Suspension Lift Kit Options
For a comprehensive upgrade, brands like Rough Country, BDS Suspension, and Pro Comp offer popular 4-6 inch suspension lift kits. Rough Country provides excellent value, often including a wide range of components at a competitive price point. BDS Suspension is known for its robust construction and lifetime warranty, appealing to serious off-roaders.
Pro Comp offers kits that focus on performance and durability, frequently featuring their own branded shocks. For a milder lift, 2-3 inch kits from Zone Offroad or ReadyLIFT are excellent choices, often simpler to install and more budget-friendly while still accommodating larger tires and improving the truck's stance. These are less complex than a full 3rd gen Tacoma lift kit installation but serve a similar purpose.
Comparing Key Features
When comparing, consider the lift height, included components, and warranty. A 4-inch kit might be ideal for fitting 33-35 inch tires, whereas a 6-inch kit is necessary for 35+ inch tires and provides maximum ground clearance. Always verify if the kit includes necessary components like differential drop brackets, longer brake lines, and steering stabilizers.
| Brand | Typical Lift Height | Key Components | Best For |
|---|---|---|---|
| Rough Country | 2-6 inches | Shocks, springs, blocks, brackets | Value and comprehensive kits |
| BDS Suspension | 4-7 inches | Heavy-duty control arms, shocks, sway bars | Extreme off-road durability |
| Pro Comp | 3-6 inches | Shocks (ES9000/MX6), springs, steering components | Performance and ride quality |
| ReadyLIFT | 2-3 inches | Spacers, blocks, SST shocks | Budget-friendly leveling/mild lift |
Prioritize kits that include components to correct CV axle angles to prevent premature wear; this is a common failure point on lifted trucks.
Where to Purchase
The most reliable places to buy a 2017 GMC Sierra lift kit are authorized dealers of major brands, specialized truck accessory retailers, and reputable online automotive parts stores. Buying from authorized sources ensures you receive genuine products, manufacturer warranties, and often access to expert customer support.
These retailers often have knowledgeable staff who can help you select the correct kit for your specific Sierra configuration (e.g., 2WD vs. 4WD, engine options). While direct-to-consumer sales are common, always vet the seller for authenticity and return policies. This avoids issues akin to trying to find parts for a niche vehicle like a Geo Tracker lift kit if quality is unknown.
The primary consideration involves purchasing from a trusted vendor.
