I'd like to make a brief review of my Dobinsons 3 inch heavy duty springs for my tj.

They were about $180 or so on Amazon. I really wanted OME but could not find any company that made heavy dusty 3 inch springs. Why did I want that? I just did.

I spent several days researching. Very little on jeep forums. As it turns out these are very popular for land cruisers and other off-road vehicles in Europe and australia. They also make them for other SUVs too.

I found some very good comparisons that convinced me to get them. On some non jeep forums, I found 4-5 people that said the Dobinsons were "substantially" better ride quality and off-road than their OME springs. I found that hard to believe. After seeing one guy with a jeep, and a truck and a couple other SUVs say this maybe there is some truth to it.

I do not have and have not had OME springs. I am not bashing them. If they made a 3 inch heavy spring I would have gone with them.

I am very impressed with these springs and gladly will buy them again. It held the weight of my bumper and winch and didn't sag at all. I drove them around my friends land a bit (he's got ravines, dirt, mud, some rocks, etc) and they were great. Very comfortable. A tad bit less flex than I thought due to the thick coils. But I see no issues with that, as heavier tires should compress them a bit more.

Frankly I thought the color was gross at first. After putting them on I actually like it. Honestly I was shocked. I thought I'd want to throw up. Not that it's hard to repaint them. Yes the red shocks look stupid. I painted them orange for the time being. They well be replaced with some bilstiens or something else hopefully soon. Painted the shocks orange to match diff guard, and control arms.

My apologies it's dark already. Meant to do this right when I got them on but waited a few weeks to see how they were. I'm impressed. 10/10 would buy again. I have no problem recommending them. My next jeep I'll get some OME springs to see how they compare. Yes my tires look stupid they are 30s and I am going to get 33s this spring. I need to get my CCW permit, and a new smaller pistol before I get tires. And to anyone that doesn't like the color, paint them. Not hard. I might repaint them at some point but I'm not sure.

I netted almost exactly 3 inches with a stock bumper, winch plate, and winch with steel cable. Advertised as being able to hold 100 pounds or so and not sag. It's been a few weeks and it sure seems to be true. Obviously that may change over the next 6 months but I hope not.

So how do they ride on-road? what kind of shocks do you have them paired with?
 
They are paired with some 0-3 skyjakcer hydro 7000s or something I peeled the sticker off and can't remember. The shocks aren't that great. The springs were an improvement over stock. Truly glad to have thrown out the spacers in the front. For now they are still in the rear but will be replaced at some point.

I'm really pleased with them on road.

I noticed a noticeable drop in "comfort" when I put in some adjustable control arms. I assume this is the transition from rubber bushings to Poly tapered bushings. Specially bumps. I've talked to a few friends that had the same experience. Living in a small town for college the road are shit so with the adjustable lowers and stock springs it sucked. And I truly don't mind an I comfrable ride. These springs made it much better.

To me the springs are a but smoother and a bit more gentle, I presume since there is more travel and they are stiffer. I will make an update in a few months for them again. I assume they will not have sagged or deteriorated.

I'd like to point out my old springs I measured them and there was less than 1/4 inch of sagging without the winch

I apologize as I have nothing to compare to.
I have had stock springs, stock springs with spacers, and these.

Yep. Poly bushings make for a horrible ride. If you can afford it at some point, put in some Johnny Joints, they ride exceptional. Also, pair those springs with some better shocks (Skyjackers are horrible too) and you'll probably love the ride even more!

My core 4x4 tier 3 arms have Jonny joints with the poly flex bushing. I heard you can swap them to rubber pretty easily?

Haha yeah I know the skyjackers suck. I needed new ones and wasn't sure if I was going to lift it last year and I got all 4 for like 150 or so. I think they were 0-3 inch shocks but they could be 0-2:eek:

Planning to switch to Bilstein or Rancho 9000 I believe it was. OME shocks are just too much. :(

Curious if I should extend my brake lines.
Now I'm running 3 inch lift front 2.5 rear, and 1.25 body lift. I REALLY love the uneven lift higher in front. It levels the jeep out super nicely.
 
I'm not sure about swapping the poly bushings, but I don't see why you couldn't. Rubber will be much, much better.

Well, one way you can find out for sure if you should extend your brake lines... cycle the suspension and see how much brake line you've got to spare when the axle is fully drooped on one side.
 
The springs will soften up a bit with use and provide a bit more travel. Take a look at the Rancho 5000X shock. Great ride on and off road, won't break the bank.

PS: I would have painted them black :D

Can you send Dobinson a note and tell them that there are no 96 or 07 TJ's, please?
When you put in the new springs, what was the change in ride height?

I'll send them an email. I noticed that. Snow on the ground so I can't measure the bumpers current height if that's what your looking for. I gained 3 inches of clearance from top of tire to bottom of fender flair.

The reason for my question is ride quality changes get attributed to a particular spring far more often than is warranted. The only way you can do an accurate comparison is if the ride height did not change.

What happens in the vast majority of the swaps is someone has a shock installed with a few inches of uptravel and they are continually being bottomed out over moderate to mild events depending on speed. The perception of ride quality will be that it is rough and harsh especially if the bumpstops are set correctly so they make initial contact with about an inch of travel left in the shock.

Pop in a new set of springs that net a bit more ride height and now the rig rides so much better and the improved ride quality gets attributed to the spring and it is actually due to the increase in ride height because the shock is no longer bottoming out over mild events.

It would also be rare to change springs without changing ride height so unless we know the before condition of all the suspension components, it is hard to assign a change in ride quality to one component.
