this is for a v10,
t for front not much stiffer then stock? but don't know the spring rate of the p's??
anyone?

thanks roger

 

I see noone has answered this one. I guess not many have thought about it.
I did exhaustive searching on this and other websites for information about the T code springs.

One person about 4 years ago indicated in a post that they were going to install the T codes, but there was no further response from them.

The T codes sound good to be able to have the soft front ride like the original springs, but the real problem is that no one has seen a T code to be able to measure and confirm the amount of arch. Any estimates that have been made regarding how much lift the T codes will give are an assumption that the T codes have the same rate of arch as all the other superduty springs.
I don't think this is the case, though. A couple of years ago, I saw a 2004 F250 at Home Depot that seemed as if the owner had installed a lowering kit. I inquired and the owner said it was stock. He allowed me to get the numbers off the springs. I took a rubbing, but I have since lost them. Anyway, I took them to my local dealer, and my favorite parts man, Duncan, told me they were T codes.

If the arch is nearly the same as the Excursion original springs, then the whole point of changing springs would be moot. We need a larger arch to get the axle away from the frame and increase spring travel.

At a couple hundred a spring, there hasn't been anyone willing to try it.

Well the impression we are getting it that the p's are b's with overload. The info we are finding leads us to believe that it is the same spring rate as b's. And you can install them with out the overload.
The T's have a higher spring rate then the stock excursion. Comparing the difference between spring rate on the stock PSD EX spring (rate 380) and the v's (410). That is about the same diffence in change as the T( v10 stock 350, to T 390). Am I looking at this wrong? My nieghbors truck has these on it and it sits good and Handles my trailer much better. Have found a set of these springs that came of a 03 when it was new. Worth trying?????

U codes work good on V10 Excursions, similar to V on PSD. Never heard of T codes, but you need the extra travel for a better ride.

 

Maybe someone can tell me this, are the rear springs with overload the same rate as the ones with out???

Well installed the t & p's. The t's on the front work good. Lift is about 1.25inch. Ride is noticable different, but not harsh like my old(90) f250. Now the P's? Put the trailer on the back to weigh it down and see. Well it just kept going down? My truck goes about 3 inch or so with out bars. Guys that have b rear spring, how much sag do you get. Got these spring cheap ( came off a truck when it was still new ), so may order a new set of b's.

thanks roger
