What’s Included: A Complete Rear Suspension Solution
During our unboxing and initial inspection, we were impressed by the comprehensiveness of this TRQ kit. Unlike single-component replacements that leave you chasing down additional parts, this bundle contains everything needed for a complete rear suspension overhaul:
- Rear Control Arms (Left & Right): Pre-installed bushings save installation time
- Rear Sway Bar End Links (Pair): Heavy-duty construction with greaseable fittings
- All Necessary Hardware: Grade 8 bolts, nuts, and washers included
- Complete Fitment: Precision-engineered for 2003-2006 Subaru Baja, 2005-2009 Legacy, and 2005-2009 Outback models
Why Your Subaru Needs This Suspension Kit
During our testing on a 2006 Subaru Outback with 142,000 miles, we documented classic symptoms of worn rear suspension components. If you’re experiencing any of these issues, this kit directly addresses the root causes:
Clunking Over Bumps: Worn control arm bushings and failing sway bar links create that annoying knocking sound during normal driving. After installation, our test vehicle’s rear end became whisper-quiet over speed bumps and rough pavement.
Wandering or Unstable Cornering: Degraded control arms allow excessive rear-end movement during turns. We noticed immediate improvement in cornering confidence, with the rear tracking precisely through highway on-ramps and mountain curves.
Uneven Tire Wear: Compromised suspension geometry accelerates tire degradation. Our alignment measurements confirmed the new components restored factory specifications, which should extend tire life significantly.
Installation Experience: What to Expect
We performed the installation in a well-equipped home garage to give you realistic expectations. Here’s what we learned:
Required Tools and Time
Tools Needed:
- Floor jack and jack stands (critical for safety)
- Metric socket set (14mm-19mm most commonly used)
- Torque wrench (essential for proper installation)
- Penetrating oil (for rusty fasteners)
- Breaker bar (some fasteners are torqued very tight)
Installation Time: An experienced DIY mechanic completed the job in approximately 3-4 hours. First-timers should budget 5-6 hours and work methodically. Professional shop installation typically runs 2-3 hours of labor.
Installation Tips from Our Experience
During our installation, we discovered several tricks that made the process smoother:
Rust Preparation: If you live in the rust belt, spray all fasteners with penetrating oil the night before. We encountered several stubborn bolts on our New England test vehicle that required extra persuasion.
Support the Suspension: Use a floor jack to slightly compress the suspension before removing old components. This relieves tension and makes bolt removal much easier—a tip that saved us considerable frustration.
Alignment is Essential: After installation, we immediately scheduled a professional four-wheel alignment. This isn’t optional; new components need proper alignment to function correctly and prevent premature tire wear.
Performance Testing: Real-World Results
We didn’t just install this kit and call it good—we put it through comprehensive testing across various driving conditions to evaluate real-world performance.
Highway Stability Testing
During 300+ miles of highway driving at speeds ranging from 55-75 mph, the TRQ suspension kit demonstrated exceptional stability. Our test Outback tracked straight without the previous wandering tendency, and crosswinds that previously required constant steering corrections became manageable. Lane changes felt planted and predictable.
Rough Road and Pothole Performance
We deliberately sought out challenging road conditions—frost heaves, expansion joints, and pothole-riddled streets—to stress-test the components. The new control arm bushings absorbed impacts smoothly without the jarring harshness of completely worn bushings, while also eliminating the previous clunking soundtrack that accompanied every imperfection.
Cornering and Handling Evaluation
Perhaps the most dramatic improvement came during spirited driving on winding roads. The upgraded sway bar links significantly reduced body roll, keeping the Outback flatter through corners. We could push harder into turns with confidence, knowing the rear suspension was working harmoniously with the front to maintain composure.
Build Quality and Component Analysis
As skeptics of aftermarket parts claiming OEM-equivalent quality, we thoroughly inspected every component before and after installation.
Control Arm Construction
The control arms feature robust steel construction with a corrosion-resistant coating that appeared well-applied during our inspection. The pre-pressed bushings showed proper fitment with no gaps or misalignment. After 2,000 test miles, we inspected them again and found no signs of bushing separation or cracking—a common failure point in inferior aftermarket parts.
Sway Bar Link Quality
The sway bar end links exceeded our expectations with heavy-duty ball joints that operated smoothly through their full range of motion. Unlike cheap links with plastic components, these feature metal-on-metal construction with greaseable fittings—a premium feature that extends service life. We greased them during installation and plan to service them every oil change for maximum longevity.
Hardware and Fasteners
TRQ includes all necessary hardware, and we were pleased to find Grade 8 fasteners rather than cheaper alternatives. The nuts featured nylon lock inserts to prevent loosening—a detail that demonstrates engineering thoughtfulness. We torqued everything to factory specifications and rechecked after 100 miles; nothing had loosened.
Is This Kit Worth the Investment?
Let’s talk numbers based on our research and testing experience:
Cost Comparison: Purchasing individual components separately (OEM or aftermarket) typically costs 40-60% more than this complete kit. We priced out equivalent parts and found significant savings with the bundled approach.
Labor Savings: If you’re mechanically inclined, installing this kit yourself saves $300-500 in professional labor costs. Even accounting for alignment afterward, you’re still money ahead.
Longevity Considerations: While OEM Subaru parts carry the manufacturer’s reputation, this TRQ kit delivers comparable quality at a fraction of the price. Based on our testing and component inspection, we expect these parts to provide 60,000-80,000 miles of reliable service under normal driving conditions.
