Bilstein 5100 shocks with OME (Old Man Emu) springs are the go-to setup for a 2-3 inch lift that rides like stock. ICON Vehicle Dynamics Stage 2 kits offer premium coilovers for serious off-roaders. Both setups allow you to run 285/70R17 tires without trimming.

Start with a lift and properly sized all-terrain tires for the biggest capability increase. Then add skid plates to protect the undercarriage, a quality set of recovery boards, and LED off-road lights. A roof rack for gear and a rear bumper with a swing-out tire carrier are popular next steps.

Yes, a cat-back exhaust improves exhaust flow and gives the 4.0L V6 a deeper, more authoritative sound. Borla and aFe Power systems are the most popular. The power gains are modest (5-10 HP) but the improved throttle response and tone are the real benefits.

A leveling kit or spacer raises the front to match the rear, fits mid-size tires, and installs affordably, but it does not improve damping. A full lift kit with Bilstein 5100s and Old Man Emu springs or ICON coilovers delivers 2-3 inches of lift plus better ride quality and off-road control. Choose leveling for looks, a full kit for serious trail capability.

A cold-air intake adds a modest 5-10 horsepower on the 4.0L V6 and sharpens throttle response and intake sound. The gains are small because the engine is already efficient, so many owners install one for the sound and improved filtration on dusty trails. It is a simple bolt-on that will not transform performance the way tires and a lift transform capability.

With a 3-inch lift, most 4Runners run 285/70R17 tires (about 33 inches) without rubbing, and some fit 285/75R17 with minor trimming. Pair larger tires with the right wheel offset and confirm your generation and trim before ordering. Bigger, heavier tires may slightly reduce acceleration and fuel economy, though the trade-off is well worth it for off-road grip.

The 4Runner's 4.0L V6 gains only about 5-10 horsepower from a cat-back exhaust, since it is already a well-flowing engine. The real reward is a deeper, more authoritative tone and slightly crisper throttle response. Borla and aFe Power systems are the most popular bolt-on options and install with basic hand tools in a driveway.
