How to increase ground clearance of Subaru Outback?
Short answer: you can gain more ground clearance mainly by lifting the suspension or by fitting larger-diameter tires; each approach carries trade-offs in ride quality, warranty impact, and potential drivetrain and calibration concerns.
Ground clearance of modern Subaru Outbacks sits around 8.7 inches, depending on model year, trim, and tire choice. Any modification that raises height shifts the vehicle’s center of gravity, changes approach and departure angles, and can affect handling and safety. This article outlines practical options, their pros and cons, and important considerations for responsible upgrades.
Why you might want more clearance
Several drivers consider extra height to improve off-road capability, tackle deeper snow, or navigate rough rural roads without scraping the undercarriage. While a higher ride can help clear obstacles, it also alters steering feel, weight distribution, and driveline angles. Owners should weigh the benefits against potential compromises in ride comfort, warranty coverage, and legal or inspection requirements.
Practical options to increase ground clearance
The following approaches vary in cost, complexity, and impact on the Outback’s dynamics. Read each option carefully to understand what it changes beyond height.
- Larger-diameter tires with careful wheel fitment: Upgrading to tires with a bigger overall diameter can add noticeable height. Stay within a size the tires and wheels can safely clear the fenders without rubbing at full steering lock or suspension travel. Be prepared for speedometer and odometer error, and potentially altered fuel economy; a re-calibration or tire-size sensor adjustment may be needed.
- Suspension lift (1–2 inches): A true suspension lift using compatible springs and shocks or a combination of spacers and upgraded dampers can raise the body more predictably than tires alone. This approach preserves tire contact with the road surface and maintains suspension geometry better, but it requires professional installation and a proper alignment; larger lifts can affect CV joints, steering geometry, and warranty coverage.
- Budget spacer lifts (0.5–1 inch): Strut or coil spacers offer a low-cost way to gain modest height. They’re quicker to install but can change ride quality and may place extra stress on suspension components; compatibility with Subaru Outback models and long-term reliability should be verified with a reputable shop.
- Selective fender work and tire clearance tweaks: In some cases, minor trimming of inner fender liners or careful attention to wheel arch clearance may be used to accommodate modest tire increases. This should be done conservatively and by professionals to avoid compromising structure or aerodynamics.
Modifications vary in difficulty and risk. If you pursue any of these options, prioritize compatibility with your model year, ensure parts are designed for the Outback, and plan for a professional installation and alignment.
What to consider before modifying
Before making changes, consider how they affect safety, warranty, and daily usability. Not all options are equally suitable for every Outback model, and some changes may require ongoing maintenance.
Warranty and legality considerations
Modifications can affect the manufacturer’s warranty and may have local regulatory implications. Dealers may view suspension lifts or tire-size changes differently from wheel-and-tire upgrades. It’s wise to check with your Subaru dealer and review local vehicle inspection rules before proceeding.
Impact on handling and drivetrain angles
Raising the ride height alters the car’s center of gravity and the angles of CV joints and the drivetrain. This can change steering feel, braking behavior, and AWD dynamics. Plan for a professional alignment after any lift and monitor for unusual vibrations or noises during test drives.
DIY vs professional installation
Decide between a do-it-yourself approach and professional installation based on the modification level and your mechanical comfort. Major lifts and tire changes commonly benefit from experienced technicians who can ensure proper fitment, alignment, and warranty documentation.
- For small adjustments (e.g., minor spacers or tire changes within manufacturer-recommended sizes), a qualified shop can still handle alignment and warranty flags.
- For 1–2 inch lifts, or when combining components (springs, shocks, spacers, and wheels), seek a shop with Subaru experience and clear documentation of parts used.
Professional installation helps protect safety, ensure proper alignment, and maximize the longevity of the modification.
Maintenance, safety, and additional considerations
After any height modification, ongoing checks are essential to maintain safety and reliability on the road and trail.
- Recalibrate the speedometer if tire diameter changes significantly.
- Get a full alignment after lifting or tire changes to prevent uneven tire wear and to preserve steering response.
- Inspect CV joints, driveline angles, and suspension bushings for increased wear, especially on higher lifts.
- Verify headlight alignment and ensure the lighting complies with local regulations; higher ride height can alter light projection.
- Consider underbody protection (skid plates) to protect vulnerable components when traversing rough terrain, which complements higher clearance but does not itself increase height.
Regular inspections after the modification help catch issues early and maintain safe operation.
Summary
Increasing ground clearance on a Subaru Outback is feasible through tire and suspension options, each with distinct trade-offs. Larger tires offer a quick height bump but require calibration and careful fitment; a suspension lift delivers more height but demands professional setup and can affect ride quality and warranty. Budget spacers are a lower-cost option with greater risk of altered handling. Always consult with a qualified technician, verify compatibility with your model year, and plan for alignment, calibration, and safety checks. With careful planning, you can expand your Outback’s capability while maintaining reliability and safety.
Final takeaway
For most owners, a modest, professionally installed suspension lift or a carefully chosen set of larger-diameter tires—paired with professional alignment and calibration—offers the best balance between increased ground clearance and everyday practicality. Always prioritize safety, warranty terms, and compliance with local regulations when embarking on height-related modifications.
