What Have You Done To Your 3rd Gen Today?

There are mathematical formulas to prove this stuff. If you preload the spring the weight of the truck must overcome that preload before it further compresses the spring. The spring compresses by an amount proportional to the force applied.

I haven’t taken a browning machine gun apart but I understand what overcoming preload is. My fingers hurt thinking about it.

 

I am running a similar setup to what you're planning. 5100's up front with 3" lift springs from Dobinson. Out back I have 5160's and a 3 leaf aal. I have the the driver side 5100 set on the 4th notch and the passenger on the 5th. This takes care of the taco lean without the need for a spacer. In regards to the rear, I left the overload spring in to keep the factory rake look. Total lift is roughly 3" in front and 2" out back. I'm very pleased with the ride quality. There are numerous threads on here and videos on youtube regarding suspension installation. Pretty straight forward if you have a basic set of tools.

 

I get what you're saying and I'm kinda on the same page. I dont do any heavy off roading and don't intend to so dont want to throw a bunch of money at it. Love the look of some of the trucks and looks like a blast but not really in my wheel house. I just want to bump up to 265 70R17 tires with some new wheels with a slight lift. Do take some trails at times with some shallow water crossings for hiking and such and that should be good enough for what I do off road.

Great explanation . Thx

 

You are correct, adding preload will raise the truck. It will not compress the spring further when loaded unless taken to extremes. The progressive wound spring adds spring rate as the softer coils become coil-bound.

The string is a good analogy. With an adjustable preload shock installed in your truck, climb under the truck and measure the installed length of the spring and make a note. Now remove the shocks and add preload. Reinstall the shocks and measure the spring installed height again. I bet it’s the same as the note you made.

I’m pointing out an example of what I mean and am not trying to be a smart ass.

 

Sounds good. Will let you know if I go that route.

 

You are correct. The spring length shouldn't change much once coilover is installed. The shock should compress then, instead of the spring. I guess I must have misunderstood your question.

 

Figured you took it out by you just getting 1.5 inch lift. Read that somewhere. Are 5160 better than 5100 in rear?

 

I don’t totally get the droop stuff in automotive suspension. I am familiar with motorcycle suspension and for fun build a set of rear shocks for our sons autocross car. We guessed and made the shocks from scratch. He won the local club class for the year but I think we could have made them better.

 

Looks great. Very similar except a little more lift. Wasn't sure whether to add spacer or use different settings for the taco lean. Thx

 

I believe they are slightly bigger (diameter) and also have an external reservoir. That doesn't necessarily make them better though. The 5125 is also an option. I believe it is basically a longer 5100.

 

Gotcha. Thanks

 

I have 6112s up front (5100s big brother) and used the same clip setting. No measurable taco lean up front. The rear on the other hand does have the lean.

 

Edit - 5100 and 5160 both share a 46mm body

 

I'd be interested. I was looking at air bags as a way of preserving ride while accommodating the occasional heavy load, but I've read up a bit on the RMAS and it sounds like it might be a worthwhile option.

 

Ok thx

 

Gave her a good wash after a weekend of offroading and added a new TRD decal just because

 

Ok. For some reason I thought the lean was because of the front hence the 1/4" spacer some use. Am I wrong about that and if so how do you correct that in the rear?

 

Milestone!
