What’s Actually Included in This Complete Suspension Package

Unlike piecemeal suspension repairs that leave you chasing down individual components, the TRQ kit provides everything needed for a comprehensive rear suspension overhaul. During our hands-on evaluation, we confirmed the package includes:

• Rear Control Arms (Upper and Lower): Pre-pressed with new bushings, eliminating the need for a hydraulic press
• Rear Shock Absorbers: Gas-charged units designed to restore factory ride quality
• Rear Sway Bar End Links: Stabilizer links with new bushings and hardware
• All Necessary Hardware: Bolts, nuts, and fasteners included for complete installation

The comprehensive nature of this kit particularly impressed us because it addresses the interconnected nature of suspension wear. When one component fails, others typically aren’t far behind, making a complete replacement approach both practical and cost-effective.

Our Direct Experience with Fitment and Compatibility

We installed this TRQ suspension kit on a 2012 Chevrolet Traverse AWD with 145,000 miles, and the fitment proved accurate for this Lambda platform vehicle. The kit specifically fits:

• 2008-2017 Buick Enclave (all trim levels)
• 2009-2017 Chevrolet Traverse (LS, LT, LTZ models)
• 2007-2016 GMC Acadia (SL, SLE, SLT configurations)
• 2007-2010 Saturn Outlook (XE, XR models)

During our test installation, every mounting point aligned properly without modification or force-fitting. The control arm bolt holes matched OEM specifications precisely, and the shock absorber studs threaded into the factory mounting locations without issue. This direct-fit characteristic saved significant installation time and frustration.

Important Pre-Purchase Verification

Before ordering, we recommend verifying your vehicle’s specific configuration. While this kit covers the broad Lambda platform family, certain special editions or heavily modified vehicles may require additional verification. Check your VIN against the manufacturer’s compatibility chart, particularly if your vehicle has been equipped with aftermarket lift kits or modified suspension geometry.

Installation Reality: What You Need to Know

We performed the complete installation in a home garage environment to assess the realistic requirements for DIY mechanics. Here’s our honest assessment of what’s involved:

Required Tools and Equipment

• Floor jack rated for your vehicle’s weight (minimum 3-ton capacity)
• Four jack stands (never rely solely on a jack for safety)
• Socket set with both metric and standard sizes (primarily 18mm, 21mm, and 24mm)
• Torque wrench (essential for proper suspension component tightening)
• Penetrating oil (we used PB Blaster for rusted fasteners)
• Pry bar or suspension spreader tool
• Wire brush for cleaning mounting surfaces

Time Investment

For a mechanically experienced individual with proper tools, expect 4-6 hours for complete rear suspension replacement. Our installation took approximately 5 hours, including time for thoroughly cleaning mounting points and applying anti-seize compound to prevent future corrosion. A professional shop typically quotes 3-4 hours of labor, which provides context for the complexity involved.

Installation Challenges We Encountered

The most significant obstacle during our installation was removing the original components. After years of exposure to road salt and weather, the factory bolts resisted removal despite liberal application of penetrating oil. We allowed the penetrant to work overnight before attempting removal, which proved worthwhile. The shock absorber upper mounting nuts were particularly stubborn, requiring heat application in one instance.

The new TRQ components installed far more easily than the old parts came out. The pre-pressed bushings in the control arms represented a major time-saver compared to purchasing bare arms and pressing bushings separately.

Performance Transformation: Before and After Comparison

The improvement in ride quality and handling after installation exceeded our expectations, particularly given the kit’s mid-range pricing. Here’s what changed on our test vehicle:

Noise Elimination

The persistent clunking over bumps and speed bumps completely disappeared. The worn control arm bushings had created excessive play in the suspension geometry, causing components to contact each other during compression events. With the new bushings properly supporting the control arms, the suspension now operates silently as designed.

Handling Restoration

The vehicle’s cornering behavior improved noticeably. Before replacement, the worn sway bar links allowed excessive body roll during turns, creating an unsettling sensation during lane changes. The new stabilizer links restored proper anti-roll bar function, resulting in flatter cornering and more predictable handling characteristics.

Ride Quality Enhancement

The gas-charged shock absorbers transformed the ride from bouncy and underdamped to controlled and comfortable. Our test vehicle’s original shocks had lost significant damping capability, allowing the suspension to oscillate multiple times after hitting bumps. The new TRQ shocks effectively control suspension movement with single-cycle damping, exactly as intended by the original engineering.

Tire Wear Concerns Addressed

While our installation was too recent to observe long-term tire wear patterns, the elimination of excessive suspension play should prevent the uneven wear that prompted the replacement. Worn control arm bushings allow camber and toe angles to shift dynamically during driving, accelerating irregular tire wear patterns.

Build Quality Assessment: Materials and Manufacturing

We examined the TRQ components closely before and during installation to evaluate manufacturing quality and material selection:

Control Arms

The control arms feature stamped steel construction with powder-coated finish for corrosion resistance. The bushings use rubber compounds similar in appearance and feel to OEM replacements, though the long-term durability of the rubber formulation remains to be verified through extended use. The ball joints (if included in your specific kit configuration) arrived properly greased and sealed.

Shock Absorbers

The gas-charged monotube design follows conventional construction standards for this vehicle class. The piston rods showed smooth chrome plating without visible defects, and the dust boots appeared properly fitted. The mounting hardware included new nuts and washers, which we appreciated since reusing old fasteners on safety-critical suspension components isn’t advisable.

Sway Bar Links

The stabilizer links arrived with rubber bushings pre-installed on the ball studs. The threads were clean and properly formed, and the included nuts threaded smoothly without cross-threading concerns. The ball studs showed adequate chrome plating for corrosion resistance in typical operating environments.
