Stage Options for Lexus GX460 w/ KDSS

Stage 1

Stage 1 offers a complete suspension kit with all the necessary components to lift your vehicle and fit custom wheels and tires for better off-road performance.

Stage 2

Stage 2 includes our Pro Forge Upper Control Arms, which help correct your vehicle's geometry back to OEM specifications when lifted. This helps reduce unnecessary wear and tear over time on your vehicle's other suspension components.

Stage 3

Stage 3 includes rear adjustable lower trailing arms for added strength and durability over stock arms while also allowing for adjustability and fine-tuning to accommodate an added lift.

Load Options

Light Load

Light load will allow your vehicle to ride similarly to stock for comfort and with little additional payload support.

Medium Load

Medium load gives you the most versatile driving experience. We almost always recommend medium load for vehicles that are occasionally loaded on the weekends but are driven daily without weight during the week. This gives your vehicle the most comfortable and practical ride for most types of off-roaders.

Heavy Load

Heavy load will allow you to carry extra weight when loaded AT ALL TIMES. We recommend this option only for vehicles that are constantly loaded with the listed minimum additional payload weight all the time. If not, your vehicle will be a stiff and uncomfortable ride.

Extra-Heavy Load

Extra heavy loads require a significant amount of additional weight. We recommend you add up all of the additional gear you will have in your vehicle at all times to make sure it meets the minimum listed additional payload. Contact our customer service before ordering extra heavy load springs.

Never exceed the vehicle manufacturer’s stated Gross Vehicle Mass (GVM). Exceeding the GVM can compromise vehicle safety, performance, and handling, and may void the manufacturer’s warranty. Always consult your vehicle’s owner manual or manufacturer for the correct GVM specifications before loading your vehicle. Use all equipment and accessories responsibly and in compliance with applicable laws and regulations.

A Company That Stands Behind Its Customers

"I haven't installed my Ironman 4x4 suspension kit yet, but I wanted to recognize the outstanding customer service I received. After my initial delivery, I discovered that one of the leaf springs was missing. I immediately opened a ticket with FedEx and sent an email to Ironman customer support. Within a very short time, their team called me directly. They had already seen the FedEx claim and told me they weren't going to wait for the shipping investigation to play out. Instead, they immediately arranged to send a replacement at no cost. The entire phone call lasted less than 10 minutes. There was no runaround, no excuses, and no passing the blame. They simply took ownership of the issue and made it right. Today, I received the replacement leaf spring exactly as promised. In a time when many companies make customers fight through endless emails and automated responses, Ironman handled the situation quickly, professionally, and with genuine care for the customer experience. That level of service deserves recognition. I am extremely impressed with how they handled the issue and I'm even more excited to get this suspension installed on my Tacoma. If the suspension performs as well as their customer service, I know I'll be happy with my purchase. Thank you, Ironman 4x4, for standing behind your products and your customers."

Great Product! Everything is top

"Great Product! Everything is top notch! Waiting on my bumpers to arrive to meet the weight I estimated for the spring loads. I’m positive it will be even better once they are installed! Super satisfied! Thank you!"

Just buy the kit, you know you want it!

"I may be a bit biased since I have started this build back in 2022, I knew I wanted to have something that was rugged and could withstand the test of time. . . Originally, I started with another well-known companies 2. 5" kit. I did my research and found this "other" kit and let me tell you, it wasn't an inexpensive kit so I thought I was good. WRONG! I added the raid series front and rear along with a winch. Next came the dual battery set up and other goodies under the hood. Over the course of the 2 years with the other kit I had to remove the front coil overs, install heavier springs and readjust them 4 times. That was 2 times too many in my book. After ordering the IM2. 5 with the heavy coils and heavy leaves out back, giving it all the beans over the last year, I've only had to readjust the suspension ONE time, ONE! To say I'm beyond ecstatic about this and the quality of the parts would be an understatement. Since I have installed the heavy kit, the ride isn't the greatest, but I'm also not done adding weight to this thing. If you are a heavy hauler, the heavy springs are what you'll want. If it's more for pushing shopping carts around Target, then the lighter side of things should suit you just fine. All in all, the install is straight forward, videos are great if you have little mechanical aptitude, and it can easily be completed and ready for the alignment shop in a mere 4-6 hours if you're taking your time. I will note, if you DO NOT have an aftermarket bumper, you will want the caster farther forward to prevent the CMC that everyone talks about. With the aftermarket bumpers I don't have that issue."

Great kit! Had professionally installed

"Great kit! Had professionally installed and after the alignment the tech claimed it was the smoothest riding lifted 4runner he’s drove. Ive had it installed for about 2 weeks and can’t believe I waited this long. I have some back issues and this kit helps dampen the bump A LOT. Only con i have is the nuts for the rear in the kit were a different thread pitch. This slowed the install by a hour or so while the shop had to go to the parts store and find one. Overall though NO REGRETS so far!"

3” IM2. 5 Suspension Lift Kit

"3” IM2. 5 Suspension Lift Kit – Ford F150 (2021+) This kit is advertised as a 3” lift with adjustable coilover system to tune ride height and different loads and driving scenarios. Let’s start with the good. The rear leaf springs and rear IM2. 5 shocks kit is well built and easy to install. Pretty straight forward. Lift the rear 3” and adds more payload. Solid 5 stars on the rear kit. I am very happy and pleased with it. Now for the front. Coilovers are about an inch taller than the OEM coilovers. That sure doesn’t sound like 3” as advertised. Called and spoke with tech support and asked them if these are adjustable. They said no, doesn’t seem to line up with the product description. Asked what the length of the strut and coilover should be. Couldn’t answer that question either. Said the website was new from changes and didn’t currently have the answer. Installed the upper control arm and strut to see how it would all line up and the UCA appears to be short. Needs to be about an inch longer to really get the camber needed. But who really know because the technical documents are really not available on their website or from technical support. After looking at the boxes sent we realized that they say test on them. What does this mean? Are they really ready for the real world? Am I a test subject? This is still to be determined. Overall on the front UCA and Coilovers their seems to be some work left to be done. Maybe a redesign? Better technical support? As far as technical support is concerned we did get to talk to someone. I didn’t get my answers to my questions. Was told to email their support email and would get a response within 24 hours. Think we are approaching 2 weeks since email was sent. Still no response. I am disappointed with that. Had high hopes for Ironman4x4. It has been a bummer to this point. To sum things up. I love the rear components and setup. Very disappointed with the frontend components. Will be looking at replacements for those. IM2. 5 gets 2. 5 stars if I could give a half star."
