Best Shocks & Lift Options for the 2025+ Toyota 4Runner
The 6th-gen 4Runner is the most capable one Toyota's ever built — new TNGA-F platform and, for the first time, an independent rear end. But the shock is now doing far more of the work, so the right setup transforms how it rides, hauls, and handles the trail.
This is our straight-talk guide to every shock and coilover worth running on the new 4Runner — from a budget setup to a full overland or desert build — and we install and dial in every one of them right here in Mesa, AZ.

What's Different About the 2025+ 4Runner
The 6th-gen 4Runner moved to the TNGA-F platform with an independent rear suspension — a big jump in on-road composure over the old solid-axle trucks. It rides better stock than any 4Runner before it. But that also means the shocks carry more of the load, so choosing the right ones (and installing them correctly) makes a bigger difference than it used to.
Two things we tell every 4Runner customer: once you go past roughly 2.5" of lift, upper control arms aren't optional — they restore your geometry, take stress off the CV axles, and open up bigger tire fitment. And if you're on the hybrid i-FORCE MAX, the extra weight matters — we lean toward load-tuned setups so it sits and rides right. Below is every option worth considering, grouped by tier and how you actually use your rig. Call us and we'll match it to your build and quote it installed and aligned.

Our Take on Each Setup

Does the new 4Runner even need aftermarket shocks?
The 6th-gen rides better stock than any 4Runner before it. But the moment you add a lift, bigger tires, or start pushing it off-road or loaded, the right shocks completely change how it drives. If it's bone-stock and you're happy, you can wait.
What's the difference between the Bilstein 5100 and 6112?
The 5100 is a direct-fit 46mm monotube — a clean, affordable level. The 6112 is a 60mm adjustable coilover with noticeably better ride quality and a real height range. If budget allows, the 6112 is the better long-term buy.
How much lift can I get, and do I need upper control arms?
Coilovers get you roughly 1.5–3 inches up front. Past about 2.5", UCAs aren't optional — they restore your geometry, take stress off the CV axles, and open up bigger tire fitment. We'll tell you exactly what your target height needs.
I have the hybrid i-FORCE MAX — does the weight matter?
Yes. The hybrid carries extra weight, so we lean toward load-tuned or heavier-valved setups (like OME or a revalved coilover) so it sits level and rides right instead of sagging or riding harsh. Tell us your trim and we'll spec accordingly.
Can I just run a spacer or leveling kit on stock shocks?
We don't do spacer lifts — ever. They throw off your geometry, wear bearings and CV joints, and mismatch the valving. We build suspension the right way, with parts engineered to work together. Buy once, cry once.
Do you install all these brands, with alignment?
Yes — we're an authorized installer for ICON, FOX, Bilstein, Old Man Emu, King and more. Any height change requires an alignment, and we handle it in-house on every lift install.
