Assessing Your 4Runner and Goals
Before diving into the fun part of picking cool accessories and upgrades, take time to carefully consider a few key factors to create an optimal customization plan for your Toyota 4Runner.
Consider your usage
Analyze how you currently use your 4Runner and any plans requiring increased capability or functionality. For example, Overlanding Adventures calls for different upgrades focused on cargo capacity and self-sufficiency compared to a dedicated weekend rock crawler build. Matching upgrades to your actual usage ensures sensible allocation of customization budgets.
Set a budget
Not setting a clear budget makes it very easy to get carried away by buying unnecessary or less impactful accessories. List out priority upgrades and determine what you can realistically afford to spend. Compromises between top-tier and budget-friendly components may be necessary to avoid draining bank accounts on a full suite of premium parts. Don’t forget to factor in professional installation costs as well.
OEM+ upgrades vs aftermarket parts
For some modifications like intake and exhaust components, Toyota Racing Development (TRD) and other OEM+ options retain factory-backed warranties while still providing enhanced performance. However, the extensive Toyota 4Runner aftermarket scene offers far more choices to create truly unique builds. Weigh the pros and cons of OEM+ versus aftermarket parts based on your goals and risk tolerance.
Most Popular 4Runner Customizations
While the possibilities seem endless when modifying any vehicle, a core set of upgrades consistently appears on customized Toyota 4Runers focused on enhanced aesthetics, functionality, and performance as mentioned on avandacar.com.
Lift kits
Adding a lift kit to raise ride height opens the door for larger tire fitments and greater off-road clearance. Old Man Emu and Icon Vehicle Dynamics offer popular suspension lift solutions retaining excellent on-road manners. Meanwhile, budget lift kits from Rough Country and Skyjacker up capability at lower prices.
Wheels and tires
Upgraded wheels allow fitment of larger all-terrain or off-road focused tires for traction benefits and unique styling. Fuel Rebels offer wheel sizes exceeding 18 inches in backspacing and offset configurations working with lift kits. Meanwhile, BFGoodrich, Toyo, and Nitto lead tire choices blending on/off-road performance.
Bumpers and armor
Protect vital components like oil pans, differentials, and transfer cases when off-roading using aftermarket skid plates from 4Wheel Parts or CBI Offroad. Adding steel bumpers with integrated winch mounts from Options NW, Pelfreybilt or Coastline also improves approach angles.
Lighting accessories
Enhance nighttime visibility on and off-road using Baja Designs squadron sport LED lights or Rigid Industries flood beams. Custom light bars and pod mounts from Heretic Studio extend functionality. Don’t forget wiring harnesses and switches for seamless installation.
Interior Accessories
Cabin and cargo space upgrades are commonly overlooked but important. Storage solutions from Decked and Adventure Wagon organize gear while Platform Creations drawer systems offer sleeping platforms for overlanding. Custom seat covers from CoverKing add protection and style.
Performance tuning
Engine power gains come courtesy of intake and exhaust upgrades from NAME, Borla, or Gibson. Suspension leveling kits lower stance while improving damping. Tuners like COBB and Stage offer custom engine calibrations awakening hidden horsepower and torque.
Build Ideas for Different Types of Custom 4Runners
The versatile Toyota 4Runner lends itself perfectly to several specific custom-built flavors depending on planned usage.
Overland build
Purpose-built for extended off-grid exploration, overland 4Runers maximize cargo capacity and self-sufficiency via rooftop tents, refrigerators, solar panels, and communications gear. Suspension lifts and aggressive tires provide terrain capability and higher ground clearance for rutted roads.
Rock crawler build
Extreme rock crawling demands maximum suspension articulation and strategically placed armor protecting easily damaged components. Front and rear differential covers from RCI add protection while Elka and King shock upgrades allow insane flexing. Chassis modifications increase clearance enabling precarious lines.
Street cruiser build
Sometimes you just want an everyday 4Runner with awesome curb appeal and presence without extreme off-road upgrades. Focus instead on massaging style with new wheels/tires, lowering spring kits, and upgraded exhaust sound. Custom leather interiors by Katzkin up the luxury factor while window tints add privacy.
Weekend warrior build
Targeting refreshed go-anywhere weekend adventure ability splits the difference between dedicated overland and rock crawler builds. Steel bumpers add utility while smaller lifts retain decent on-road handling. Roof racks expand cargo flexibility and allow mountain bike access. Prioritize value spending for function over flash.
