Built for the Extreme
Heavy-Duty Performance Suspension
WHY FOAM CELL PRO EXISTS
Foam Cell Pro didn’t start as a consumer product.
It started as a military requirement.
The original brief was simple and unforgiving: build a suspension system that could operate reliably in extreme heat and cold, carry the constant weight of up-armored vehicles, and survive day after day of harsh terrain and abuse — without failure or maintenance interruptions.
Complex adjustable valving wasn't the priority. Dependability was — so operators could focus on the mission, not their equipment.
That requirement shaped everything that followed.
THE MECHANISM
Foam Cell Technology — Built for Heat and Load
Most gas-charged shocks rely on pressurized nitrogen. Under prolonged heat and heavy use, that gas can aerate — leading to fade and inconsistent performance.
Foam Cell Pro takes a different approach.
By replacing nitrogen with a high-density foam cell sleeve, the system:
- Eliminates cavitation
- Maintains consistent damping
- Handles extreme temperature swings
- Performs reliably under constant load
This is why Foam Cell Pro excels in:
- Long-distance touring• Heavy accessories (bumpers, winches, drawers)
- Towing
- Sustained off-road travel
Ride Quality
Suspension should start with the job required of it — not the spec sheet. Foam Cell Pro is engineered around that principle.
- Controlled, planted behavior on road and trail
- Predictable handling under load — bumper, winch, drawers, and all
- Geometry maintained as your build adds weight over time
This is not a race shock, and it is not built for constant tuning. It is matched to the truck you are actually building — the one that gains weight with every accessory and needs to stay dialed in as it does.
That is the kind of quality you appreciate on year three, not just mile three.
Foam Cell Pro vs Remote Reservoir Shocks
What Remote Reservoir Shocks Are Optimized For
Remote reservoir shocks are excellent at:
- Increasing total oil volume, improving thermal capacity
- Improving heat management during repeated high-speed cycling
- Often offer compression and/or rebound adjustability
- Support performance-oriented valving for aggressive driving conditions (i.e. racing)
They are commonly chosen for:
- High performance-focused builds designed for speed
- Highly aggressive off-road driving styles
- Applications involving repeated high-energy terrain
- Owners who prefer tunable systems and understand servicing will be required
Remote reservoir shocks do not equal “better” but serve a different performance priority. Maintenance depends on usage, not just design.
What Foam Cell Pro Is Optimized For
Foam Cell Pro is engineered for:
- Consistency over long distances
- Constant vehicle load
- Extreme temperature swings
- Minimal maintenance
- Set-and-forget reliability
Foam Cell Pro increases oil volume internally and replaces pressurized nitrogen with high-density foam, eliminating cavitation and reducing fade without external components.

Reviews
Looks Good; Feels Good
"I bought a brand new 2024 Toyota 4Runner SR5 Premium and immediately installed the TOY065AAKPS3P - Foam Cell Pro Suspension Stage 3 kit with medium rate springs. The ride on pavement was noticeably tighter. It corners like a sport sedan, and the nose dive while braking was now gone. I have done some mild off-roading and it does really well. I have towed a small camper and largest u-Haul trailer. Virtually no sag under load while towing. I really like this kit. It seems well engineered and well executed."
Definitely DIY installable, I’m replacing
"Definitely DIY installable, I’m replacing my first lift that is okay for a high school kid, I’m 70 so comfort is key on my fly fishing outings , my 17 ,6 speed manual Tacoma is decked out fully ."
So far so good
"I have had this 3. 5in foam cell pro lift for a couple years now and didnt want to leave a review right off the bat. I have medium duty springs front and back. At the time they only had the black springs for an option. Personally I would have rather had the green springs but oh well. I also have the upper control arms. The kit has served me well. I dont do alot of extreme off roading but have done some. The ride has been good on and off road. Better than the factory trd offroad setup. It took out the lean in the corners for the most part When I 1st had it installed it was a little noisy for the 1st 4 month or so in the front springs as far as squeeking sounds intermittently getting in and out of the truck and taking slow corners but it has worked its self out and I haven't noticed the sqeeks in a while. Customer service was great to work with and no matter how dumb my question was they took the time to answer. I would like to get their front bumper next but time and money will tell for that one day."
I love the new look and feel
"Had the 2” Foam Cell Pro lift kit installed and I immediately fell in love with the way my 200 series Land Cruiser looked after. Though it’s higher than 2” and it’s still new and settling in. I bought it to upgrade my worn out factory suspension. And to do some off-roading. Haven’t had the chance to test that out yet. But the ride is still comfortable for regular day to day driving, just looks better doing it now. Pics don’t do the looks justice."
Great quality, customer service is
"Great quality, customer service is top notch. Was not as simple to install as video implied, but took it to a shop and they installed for me. Stoked on the finished product, just what I needed for when my camper shell is installed."
This is the 2nd kit
"This is the 2nd kit I've purchased from Ironman. Planned to install it in a couple of weeks. 1st kit was great."
Switched to Foam Cell Pros from Bilstein 8112’s
"I made the switch to Foam Cell Pros from Bilstein 8112’s on my 5th gen 4Runner. I ran the 8112’s for 2 years and they were great units however they were always noisy (normal due to internals per Bilstein) and the Bilstein zinc shock body finish is garbage- regardless of using FluidFilm to protect in the winter months. I was most impressed with the quality and fit/finish of the Ironman kit and what a stellar ride you get with the Ironman setup. The whole kit was well packaged. The only issue I had with install was having to lookup on the Ironman YouTube page was the correct orientation of the rear shock top mount bushing. It would be nice if that was explained in the directions provided but easy enough to watch their video to see exactly the right order of washers etc. When I placed my order on a Tuesday night my items did not ship out until the following Monday which was frustrating however the fedex shipping got the package to me by that Wednesday. I am happy with this product and would recommend it to other 5th gen 4Runner owners. I hope the finish on these suspension components hold up better than the Bilstein. Thanks."
Easy install, fast shipping, great ride
"Arrived quickly, only problem with delivery was one of my rear shocks poked out of the box and I was worried about the threads being messed up but everything was good. Install took about 4 hours for all 4 corners. I’m convinced my truck is higher than 2 inches but the factory rake was kept and it looks great. I went with heavier springs front and rear, the front was just light load but I went medium with accessories in the rear and it is heavy duty. Body roll is almost non existent, it takes hard hits much easier now. The ride is much stiffer but I knew what I was getting into. Once overlanding season rolls around again I’ll have more weight in the bed and it should even out. Overall very happy, I only have about 500 miles on the lift so far and haven’t taken it offroad. One suggestion I have for anyone getting this kit is to get extended brake lines or a bracket to relocate brake lines. Tundras are very short in the rear. I would go with the extended panhard bar better yet a panhard bar relocation bracket that."
Absolutely great lift kit! All
"Absolutely great lift kit! All the parts are great quality and the install went smoothly. No clunks or bumps, and the ride is much better than before. 100% recommend!"
Q&A
- Is this considered a long-travel suspension?
- It is extended travel not long travel
- Do i need to get the diff drop with this lift?
- No, you do not need to get the diff drop with this lift kit.
- Do I need to purchase UCAs or can I utilize stock UCAs?
- With the Foam Cell Pro lift kit, you will need after-market UCA's. These will clear the larger diameter coilovers, clear larger tires, and move the ball joint allowing for proper caster alignment. Your stock UCA's will hit the coilovers at full droop, will rub on larger tires, and won't allow for proper caster alignment after the lift. Our Stage 2 suspension kits include UCA's, click here to see Stage 2.
2-3" Foam Cell Pro Suspension Lift Kit for Toyota 4Runner (2010-2024) Non-KDSS FAQs
What is Foam Cell Pro designed for?
Foam Cell Pro is designed for durability, consistency, and long-term performance under load.
It is ideal for:
- Vehicles carrying constant weight (bumpers, winches, drawers, campers)
- Towing
- Long-distance touring
- Rough terrain over extended periods
- Owners who want reliability without tuning or rebuild schedules
It is not designed as a race or high-adjustability shock.
How is Foam Cell Pro different from Lift & Level or Nitro-Gas kits?
Each system serves a different purpose:
- Lift & Level — Improves stance and tire clearance while maintaining factory-like ride. Budget-friendly. Not intended for off-road use.
- Nitro-Gas — Stronger than OEM, suitable for daily driving and light off-road.
- Foam Cell Pro — Built for heavy load, heat management, long-term durability, and heavy off-road use.
- IM2.5 — High-performance monotube suspension focused on responsiveness and comfort on and off-road.
Foam Cell Pro sits in the durability-first tier.
Why does Foam Cell Pro not use gas like other shocks?
Foam Cell Pro uses high-density foam instead of pressurized nitrogen.
This design:
- Eliminates gas cavitation
- Reduces shock fade under sustained heat
- Maintains consistent damping over long distances
- Performs reliably in extreme hot and cold conditions
This is the core reason Foam Cell Pro excels under load and over time.
Is Foam Cell Pro adjustable?
Yes, it is ride-height adjustable only. Foam Cell Pro is a set-and-forget suspension system, once you customize to your build’s unique ride height needs when installing.
It is engineered with vehicle-specific valving to deliver consistent performance without:
- External adjusters
- Tuning knobs
- Rebuild intervals
If you want to adjust the tuning, you will need to rebuild the shock and adjust the valving and shim stack.
How does Foam Cell Pro ride on road?
Foam Cell Pro delivers a controlled, stable, and planted ride.
Compared to factory suspension:
- It may feel firmer when unloaded
- It feels more composed and comfortable when loaded
- It improves stability when towing or carrying accessories
This is intentional and part of its durability-focused design.
Is Foam Cell Pro comfortable for daily driving?
Yes, especially for vehicles that:
- Carry accessories
- Tow
- See mixed on-road and off-road use
If your vehicle is completely stock and you only want a softer factory feel, Lift & Level or Nitro-Gas may be more appropriate.
Does Foam Cell Pro provide lift?
Yes. Foam Cell Pro kits are designed to:
- Increase ride height up to 4”
- Correct stance
- Support larger tires
Exact lift height depends on vehicle configuration and load.
Do I need other upgrades to run Foam Cell Pro?
No additional upgrades are required but performs best when used as designed.
Foam Cell Pro is best paired with:
- Steel bumpers
- Winches
- Drawer systems
- Canopies or campers
It is designed to handle this added weight and reaches peak performance when under additional load.
Is Foam Cell Pro good for towing?
Yes. Foam Cell Pro is well suited for towing, providing improved stability, control, and consistency compared to OEM suspension.
Is Foam Cell Pro rebuildable?
Yes, it is fully rebuildable so you can buy once cry once.
However, Foam Cell Pro is engineered for long service life without routine rebuilds. This reduces maintenance, downtime, and long-term ownership cost.
