New Dobinsons 31" Long Front and Rear 2.6" IMS Shocks for 80 Series

[crikeymike]

Hey Guys

Apparently several of you maniacs out there felt that the existing Dobinsons IMS shocks to suit a 6" lift on an 80 Series weren't long enough, so Dobinsons went ahead and built the longest IMS shocks they make to date. Now there are 0-3", 4-5", 6", and these long bois for front and rear in the IMS range.

Introducing these new length Front and Rear IMS shocks. Still waiting for the photos to get taken and cleaned up.
Rears just arrived yesterday. Fronts are coming soon.
Here are the specs:

IMS59-60689 - Front - 790mm (31.1″) extended, 467mm (18.4″) compressed
Factory mounting top and bottom
2.6"/66mm Body size with 60mm pistons
Same linear valving as existing IMS shock lineup for 80 Series

IMS59-60681 - Rear - 790mm (31.1″) extended, 480mm (18.9″) compressed
Factory mounting top and bottom
2.6"/66mm Body size with 60mm pistons
Same linear valving as existing IMS shock lineup for 80 Series

General info about the IMS shocks:

• Fully rebuildable and re-valvable
• SOLD IN PAIRS
• Zero shock fade in all terrains with full load
• Direct, bolt-on replacement for easy fitment
• IFP – Internal Floating Piston, separates oil and nitrogen
• Corrosion resistant (EDP Surface Protection)
• Heavy duty single piece lower leg
• Enormous oil capacity
• Heavy Duty 3 Stage FKM HNBR Sealing System for the ultimate in reliability
• Race inspired hi-flow CNC 6061 Billet alloy piston – for the ultimate in offroad handling
• 66mm/2.6” Bodied Series – 60mm hi-flow CNC 6061 Billet alloy piston – 60mm bore – Vehicle specific fitment – Suitable for most heavier vehicles
• Full 2 year limited warranty, no set rebuild time period
• Bump stop extensions are required to prevent bottom outs, depending how you mount the shocks

I've also updated the 80 Series Dobinsons Shock page that shows every front and rear shock type as well as steering damper on one page, making it easy to see it all at once and the pricing as well.

Also, going to throw this other thread in here as well, as there are universal 3-way adjustable shocks that just came in as well.

New Dobinsons MRA 2.6" Universal Smoothie Shocks - 10", 12" and 14" Travel

Sharing the news on these new products that Dobinsons seemingly pulled out of nowhere!! These are the newest additions to the 3-Way Adjustable MRA Shocks that Dobinsons have had for quite a few years, and these are called the Smoothie Series. Referring to the zinc plated DOM 3mm steel shock...

I may have to make a change to these in the rear of my Cruiser later this year. Been looking for something with more dampening than the twin tube but with some real travel

I LOVE my IMS shocks but I'm not a fan of the limitations of the 4 to 5" shock with a 3" lift. The 6" shock was released a month after I purchased my shocks and I would have definitely purchased them knowing what I know now.

Luckily the shocks are long lasting and the resale market for them is strong, especially on here, so you can sell those and buy the others for a small price difference.

These look interesting. Has anyone tried them out yet?

Been looking into upgrading my oem shocks with the IMS. Does anyone have any experience with oem springs paired with IMS shocks? Thanks

@crikeymike I have a few questions for you as I look into these. First, what sort of shaft protection is recommended on these in the rear? Second, I have 145VT coils in the rear of my Cruiser with 30mm spacers on top. What bumpstop spacer would you suggest I stuff in there to make these behave. Thirdly, how do these seem to play with rear sway bars when being extended on rocks? I know that one is subjective, but curious what you've seen. Lastly, these in stock?

They come with rubber boot shaft protectors.

Bump stop spacing depends on the rest of your setup and tire size used. There aren't any "you'll need this long..." Specs for them, but they'll have to be long extensions most likely due to the long compressed length of them.

I don't think you can successfully use a stock sway bar with these. You'll have to do an anti rock or custom sway bar to achieve the droop these can give you.

They're in stock.

They don't come with shaft protectors. The boots Dobinsons normally use aren't long enough for them.

That all seems to make sense. I'll just have to get some square stock out and make some spacers. No biggie. The damping on these should be massively improved at my weight over the twin tube yellows anyways. And then just to find some shaft protectors. Thank you Mike!

Ordered. We're gonna give them some good rocks to eat this summer

I am running the 6" IMS for the front and 4" for the rear with about 3.5" of lift

They showed up yesterday. That was faster than I was expecting. I was also pleasantly suprised to see how really nice these are and that everything to get them in was correct in the box. Even have shaft boots on them. This weekend I'll be making some new upper shock mounts to space them up a touch for my purposes. I'm excited to give these a good run on the Rubicon in 2 weeks

I just realized I got confused with these shocks and the Smoothie shocks. The universal Smoothie shocks have no boots, but these ones do.

Well this is completely devastating. I broke the cast stem off the top of one just after install and flexing it on the property. Looks like it’s totally my fault. The upper mounts I made put the stem too close to the bottom of the body and it made contact when flexing and sheared.

Damn. To your other question, Timbren bumpstops all the way. I’m sure I posted about my setup using same coils if you search.

You really want to get rid of the hard stop just by extending the stock bumpstops. I don’t run swaybars and this type of bumpstop with dual rate coils is money (for not much money).

Hope you get the shock situation sorted.

Hmm, I'm considering this setup but a bit concerned on the reduction in up travel. Anyone have any issues when getting off camber? Seems like with the body getting pushed over a bit more now with the extended bumpstops, rolling seems like a bit more likely?

Coming from some OME suspension, I'm wanting to change over to something with more flex so considering these or the the 28"

These shocks are excessive for most, more like for people that have built custom shock mounts and are going to use all the travel. (like people that have 3-linked suspension, as an example).

The regular 4-5" length shocks are most suitable for max up and down travel, in my opinion. The 6" length shocks would be 2nd best, and these 31" long ones are really for specialized use.
