What is a great shock for an increased spring rate? I am not only concerned about shock compression. I am also concerned about shock REBOUND with the higher spring rate front coil springs. The toxic shocks are still very hard to compress (harder than bilstiens) but I "think" that the shocks are not keeping up with the rebound of the higher spring rated stock coil springs that I cut for a 3 and 1/4" drop.

 

You cut too much off, but, you could try Bilsteins. Also make sure you use shorter bump stops.

 

Shocks do not have a spring rate. They just dampen the springs. 3" cut from the sock springs is not something that will feel right with any shock. Why not buy lowering springs?

 

You are correct, but they do have compression and rebound rates.

 

Thanks for the input everyone. Sorry, I did not formulate my question correctly. What I meant was that, I cut the front coil springs for a 3 and 1/4 inch drop. By doing so, I not only got the exact lowering I wanted, but I also greatly increased the spring rate.

I wanted to do this. I had tried DJM lowering springs, but the springs did not have an increased spring rate and did not lower the front end to the exact amount I wanted. I increased the spring rate to reduce the effects of cross-wind induced body roll. The increased spring rate has reduced cross-wind body roll better than anything eles (larger swaybar, stiffer shocks, wider lower profile tires).

I was wanting to know, what shocks had a high rate of rebound to "keep up with" and control, the higher spring rate rebound.

.........I could try some belltech 3" drop coil springs since they seem a little stiffer than stock, but I would not get the exact drop I was looking for and I would lose the higher spring rate-anti-cross-wind body roll effects.

Would I be better off with replacing the higher spring rate cut coils with standard 3" lowering belltech coils or should I look for front shocks that have a higher rebound rate to compensate for the higher spring rate rebound of the cutt coil springs?

 

How do you figure that you increased the spring rate by doing that? I don't think the stock springs are progressive rate so that now you are now always at a higher rate. You just have less travel. I highly recommend finding a good lowering spring. I have no idea what a "good one" is (torson bars on 4WD)m though so maybe someone else can step in.

Sure, I understand the benefits besides looks. i jus tthink cutting springs is a poor way to accomplish that. On top of that, it makes it difficult to find a good matching shock because. The shocks that you need for a lowered truck, do not work well with low rate springs. Yet, the shocks designed for those springs, depend on the full suspension travel. Take a look at a shock catalog. It has different part numbers for stock height, lowered, or lifted.

I recommend finding a lowering spring that will give you the look you want and then a mating shock designed for lowered suspension. May be best to start a new thread for that, or I am sure a search will find plenty of discussions.

 

Good and critical point.......does cutting a stock spring increase the spring rate ? According to all research-yes it does.

When you cut a spring you not only lower the stance, you also get a MUCH stiffer or higher spring rate spring, as well as having less spring travel. A stiffer spring with less travel equates to a much faster rebound. I know they make shocks for higher spring rate, faster rebounding springs (koni, QA-1s, etc.) I just do not know which one works well with cut springs that are very stiff and have a very high spring rate

 

I just did a little research and found conflicting evidence. Anyway, I'll take your word for it for now.

Anyway, to answer your question that I kind of already implied, fidn a shock that is designed for lowered suspension. Rancho, Bilstein, and Edlebrock all do.

 

Thanks. Yeah, I spoke to a guy that worked at a shop that made springs. He confirmed that if I cut the stock springs, it would greatly increase the spring rate, therefore, I would have a very stiff spring. He was right. It reduced body roll due to cross winds better than any other mod. .....so far. However, with my toxic shocks the stiffer springs produces a short and very fast "bounce" effect sometimes. I need to find a shock with an increased rebound dampening ability for F150s.
