Dobinson IMS lift

[ElixerGxer]

Anyone running the ims lift with 1.5" front springs and the .5" (1" total with spring conversion) rear springs. At 140k on orignal suspension she's getting a little tired. Just looking for something super mild, probably going to go with 265/70 wildpeaks once the michelins wear out.

Opinions on ride quality and pics are greatly appreciated!

Don't have IMS but do use MRA and I am pretry happy with their performance.

If you just want something mild Eibach might be another good option. Just becaue it was already packaged with specific spring and intended for stock load vehicles.

I am more of a suspension junkies although far from an expert. Knowing what I know from dealing with a lot of suspension, valving matching to the load and spring are the most important. This can only be achieved by:
1. Fixed shocks paired with specific spring intended for specific load.
2. Custom valved shocks to match spring and load.
3. Adjustable rebound and compression shocks with proper load spring.

Being IMS are not valving adjustable, they must have pretry generic valving to cover all the spring options they have. Being based in Australia, they probably designed for medium load vehicles that is the most common for their customers.

They are linear valved monotube shocks. So they are very good at their price point. Especially for people that use it off road with medium load.

I was in this debate with myself as well last year. Ended up doing Nitros due to budget and the fact that I rarely off road the truck.
I did the Dobs Nitro set up, 1.5 inch lift (due to fear of KDSS complications on my particular truck), all comfort specs/weights. I found the .5 inch rear springs don't really need the spacers. They seem to lift GXs .75-1 inch on their own. I ended up taking them out as I had quite a frontward rake. Used the AllDogs kit to install later on and the truck is level now.
I find the ride to be very comparable to stock in sport but with less boatiness. It is still soft and not jarring. It absorbs big bumps beautifully. Small road undulations can still transfer, but I feel like that's just the nature of solid rear axle vehicles. I've experimented with different tire pressures to help with the smaller stuff that doesn't seem to be enough to compress the rear springs, and settled on 30 and it is quite comfy. Tire place set my tires at 44. I have no complaints after lowering tire pressures and would install it again. It feels great on washboard roads, speed bumps, big expansion joints, etc. The stock suspension would have a lot of secondary movements and weaving and bobbing and sometimes hit the bump stops. This feels a lot more planted, still absorbant. You really notice it most over potholes, expansion joints, etc. It's just boom one and done, absorbs the impact, and the vehicle body just floats over it all.
I had a chance to feel out an Ironman FCP set up on an LX470, and an Eibach on a GX470. FCP felt the stiffest. Eibach and my Dobs set up felt very similar.
