Insurance premiums tend to rise for models with higher theft risk (e.g., 2000–2006) or recall-related liability, which applies to some 2013 units involved in Takata airbag lawsuits.

Which Years of the Toyota 4Runner Are Best for Off-Roading?

The best Toyota 4Runner years for off-roading are 1999–2002 (3rd gen) and 2016–2021 TRD Off-Road and TRD Pro trims.

What factory off-road features vary by year (e.g., crawl control, A-TRAC)?

Toyota introduced A-TRAC (Active Traction Control) and Crawl Control in select trims starting from 2009. Here’s how capability evolved:

• 1999–2002: Offered a rear differential locker in the SR5 and Limited trims with manual 4WD, highly regarded for simplicity and dependability.
• 2010–2013: First 5th-gen models offered A-TRAC on Trail Edition, but no Crawl Control until 2014.
• 2016–2021: TRD Off-Road and TRD Pro trims added Multi-Terrain Select, Crawl Control, and KDSS (Kinetic Dynamic Suspension System), allowing better articulation on uneven terrain.

These factory systems provide true off-road advantages, especially in loose gravel, rock crawling, or steep descents.

Which trim levels are most off-road capable?

The TRD Pro and Trail Edition trims from 2015 onward are the most off-road capable, thanks to factory upgrades such as:

• Bilstein or Fox shocks with increased suspension travel.
• All-terrain tires with 17-inch wheels for ground clearance and traction.
• Skid plates and roof rails for utility and durability.
• Standard 4WD with rear locking differential.

These trims outperform base SR5 and Limited models, which are more road-focused and lack crawl and terrain-select features.

What Should You Look for When Shopping for a Used Toyota 4Runner?

When shopping for a used Toyota 4Runner, you should inspect the frame, verify maintenance records, test the 4WD system, and avoid high-risk model years like 2003, 2005, and 2010.

Should you buy from a dealer or private seller?
