Ironman 4x4 Suspension for 40/45 Series

[FJ40 that green thing]

Here's another one with more technical details.

 

[FJ40 that green thing]

Same to you sir, I did a lot of research as well and took me 3 months to learn those differences, so far ironman pro has the best to offer regarding multi-purpose function at a reasonable price, however I am a bit worried and sad for this shocks, it is so underrated and you are the first 40-45 series owner to use this FCP. Swear, everyday i am on google, YouTube or any other platforms and yet I haven't seen a single review of FCP for 40's. I am happy to see this sir, I appreciate it. by the way sir, your FCP has item number of Front=45635FE and REAR=45646FEC , and both eye-ring mount from top and bottom. am i right? if you have instagram sir please tell me so i can follow you THANKS!

Yes, eyelet at the top and bottom. They'll fit your 40 just like any other shock would. I had them all changed out in under 1/2 hour.

These are far better than your average Monroe shock, so they do cost more. Here are a couple videos that helped me understand the difference and decide to try them out.

While I can’t be sure, I think I have known about them longer than you. I became a distributor for Ironman around 2011 IIRC.

65swb45/ Mark and others
Seems like you have a good deal of experience with ironman. I have been looking at 2.5 lifts for my 1981 fj40 (and although popular compete kits) I have been leaning away from OME given the shorter spring length and relocation of axle forward in rear wheel well.

What has been your experience with ironman springs on fj40s

Had this discussion Evan, just a couple of weeks ago in this forum. I really believe the secret sauce is the shackle angle.View attachment 2837029

looks good Mark. relocated shackle hanger and/or longer springs? what springs are those - 40 ironmans?
been considering basing my next spring set on longer springs like 60 rears or relocating the shackle hangers for off the shelf 40 parts.

Yes ! I received mine! Hehe with foamcell steering damper . How did you fully extend your shocks? By means of gravity pull through hanging? Thanks

That's great. No disrespect, I'm sure you know all about them and ironman has been around for a while. I could be wrong but after searching the forum and elsewhere I couldn't find anything about Ironman suspension on the 40 series. Have you posted about it before? The point of my post is to help others considering lift/suspension offerings for their 40 series as I know I would have very much appreciated any information before making the investment. Photos, performance, installation details, price etc. are all very useful.

 

[judemiks]

Judemiks, The Foam Cell pro is an upgraded shock absorber. The girth of the shock is a good inch or so bigger than a standard gas charged shock. I was surprised and impressed with them, seem to be built very well. If you read up on them, the technology was developed for military use I believe. The idea is they won't overheat and lose performance with heavy use. When the truck is loaded down with people and gear it still handles very well. It's hard to say how much better they are than the gas charged shocks but I believe most people would agree they're better.

Hi there, can you show me the picture of your front mounting of your fcp specially the upper mount. I am really concerned about the clearance. I find that the fcp has a large girth. Did you change or modified some parts or just stayed in original ? Thanks.

I have since sold this machine. THe shock fits fine in the shock tower, no problems whatsoever. I did have some slight rubbing on the steering arm and eventually swapped the FCP shock out for a regular FC shock that is smaller in diameter. Hope that helps.

I haven't had the chance to run them yet, but I've installed the Ironman springs and shocks on my '65 FJ45, the front FCP shock barely clears the drag link with a stock steering box by about 3mm. The rear shock has an offset lower mounting eyelet, helpful feature. The rear springs are pretty heavy, hoping they ride nice.

 

[65swb45]

I posted up SOMEWHERE on the forum about outboarding the lower shock pin a little closer to the knuckle ball to get the necessary clearance from the drag link.

 

[Rooster47]

25% off right now. Thinking about pulling the trigger. I run a lot of washboard roads around here, wondering if those foam cells are good for that?

 

[carlosfj80]

Does anyone know if you can run just the Ironman shocks without any lift? Not sure I want to lift the 40. I’m sure it would look good but then I have to buy bigger tires…

You might try going to their site and checking it out.

I think they have different sized shocks. Good question for customer service, I've found the staff answering the phones over at Iron Man to be really good at getting answers.

I know this is an old thread, but were these springs mounted with the OE spring/shackle perch locations? This shackle angle and axle location is perfection.

I couldn't find ANY (I mean, nothing) information on the Ironman 4x4 brand suspension systems for the 40/45 series Land Cruiser on the webs or forums so I wanted to contribute what I learned here on Mud. This truck still had the original factory suspension including shock absorbers when I bought it. After adding a few accessories and a RTT, the vehicle unsurprisingly became unstable and too soft for my comfort off-road, not to mention the lack of clearance. Last summer, after researching available lift kits for the 45 series truck it seemed there were 3 good options on the US market for the 45 pickup. OME, Dobinsons and Ironman. After consulting with a few forum members and my own experience with these brands, I decided to give Ironman a shot. Their springs give approx 2 1/4"-2 1/2" of lift and they offered the Foam Cell Pro shocks as well. So far, I have to say I am super happy with the setup and Ironman 4x4 has been excellent to work with. After getting everything dialed in, the ride is very good (for a 40) and handles the weight well on and off road. Ironman seems to be expanding rapidly with their product offerings in the states and their lift kits it seems are common on more modern vehicles but I have to say I have no regrets on this kit for the FJ45. I would consider Ironman suspension for other vehicles. I have suspicion that many of these lift components like the spring packs are made in the same plant and private labeled if anyone has any additional insight or experience, please chime in. Pricing was also very reasonable and they have 25% off sale on lift kits often. See: Ironman 4x4 America | Off-Road Truck Equipment & Accessories - https://ironman4x4america.com/
