Best Bolt-On Upgrades for 2025+ Toyota 4Runner

The sixth-generation Toyota 4Runner is the latest and greatest of the iconic and successful off-roader. It has been on the market for not so long yet, but the aftermarket wasted no time, as the upgrades are coming in hot! If you’re rolling in one of these brand-new off‑road warriors, why don’t you crank it up a notch? Here are some of the best and simplest bolt-on 4Runner mods to make your ride more capable of tackling the beaten path.

Rough Country 3.5” Lift Kit

Let’s start with the obvious. If you’re looking to get more off-road performance, you lift your ride first and foremost. Rough Country is one of the most reputable names when it comes to suspension lifts, and their 6th-gen 4Runner kit is engineered for the adventures of any kind: from rocky trails to muddy backroads, all the while making your 4Runner look the part.

The kit includes upper control arms, a rear track bar bracket, and rubber bushings for enhanced durability and perfect balance while adding extra ground clearance. It is a bolt-on suspension upgrade with hassle-free installation.

35” Tires and Wheels

Another obvious one: 35s. The 4Runner can handle up to 33, but anything bigger than that requires bumper trimming. But if you’re lifted enough, a combo of 8.5×18” wheels and 295/70R18 tires slots right under the fenders. That means you get massive, meaty treads for mud‑slinging traction and rock‑gripping G‑force without hacking up the brand new bodywork.

Magnaflow Overland Series Cat-Back Exhaust

Magnaflow’s Overland series exhaust system is built for off-road function, and replaces the stock components after the catalytic converter. The kit offers better clearance, keeping your 4Runner clear of any challenging terrain or obstacles in your off-road adventures. 

The exhaust is made out of 3″ diameter mandrel‑bent stainless-steel piping and features No Drone Technology (NDT). MagnaFlow’s NDT utilizes passive quarter-wave noise cancellation to minimize the droning.

Prinsu Pro Roof Rack

Prinsu’s new Pro series roof rack turns your 4Runner’s roof into a gear-hauling space for immense practicality. The all‑new crossbar design flexes 44% less under load, giving you rock‑solid confidence when your kayaks, boards, or expedition packs are strapped on. With its six integrated drop‑in points per bar, you can mount lights, shovels, jerry cans—whatever you desire to the rack.

Installation is fully bolt‑on and completely reversible, as no holes are drilled into your roof rails. Stainless‑steel hardware makes the unit rust-free, and the two‑part rail with reinforced bends makes flexing a non‑issue. With a jaw‑dropping 700 lbs dynamic and 1,200 lbs static capacity, you’re basically hauling BIG up there.

CBI Rock Sliders

Now it’s time to defend your new 4Runner against the obstacles and challenges of off-roading. CBI rock sliders stand between your fresh rocker panels and those nasty obstacles. Made from heavy‑duty DOM tubing, they offer exceptional strength to take hits so your frame doesn’t get scratched.

They bolt directly to the chassis—no trimming or welding—so you keep factory strength with an extra layer of armor. Beyond the protection, they double as jacking points. The optional black powder coat finish fights corrosion, keeping that matte‑black menace look sharp.

CBI Full Skid Plate Kit

Speaking of extra armor, underneath your 4Runner lies a minefield of vulnerable and expensive components. You need armor there, too, and it comes from CBI’s full skid plate kit. It locks down front and rear with high‑strength aluminum guards that shrug off rocks, dips, and trail debris. Each piece integrates with existing mounts, so, again, no drilling or hacksawing—just bolt up and head out.

Strategic access ports mean you can change fluids without removing the plates, saving you (or the mechanic) time when it’s time for a service. Choose bare aluminum or black powder coat to match your rig’s vibe—and rest easy knowing every inch of undercarriage is defended.

Fukin Tuned Throttle Response Controller

To tie up everything and boost the off-road performance even further, you have to lose that pesky throttle lag. Fukin Tuned throttle response controller is the sleekest and most effective way to do that. It seamlessly integrates into the gas pedal position sensor and modifies the stock throttle signal. You can dial in the perfect throttle response with four driving modes—Slow, Cruise, Fast, and Send It—and 36 sensitivity settings.

Get full control of the throttle action: Smooth it out for precision off the road, bump it up for better city driving, or get razor-sharp response when you need raw power on the trails. Fukin Tuned throttle response controller installs in minutes, and is controlled wirelessly from your mobile phone. On top of all that, it doubles as a seamless kill switch—protect your rig with the built-in Anti‑Theft feature in that remote area for complete peace of mind.

Best of all, it won’t void the warranty on your brand-new 4Runner, so you can bolt it on, blast off, then remove it before a service appointment with zero trace left behind.

Get ready to unleash the beast—transform your 4Runner with the best plug-in upgrade!
