I was planning to install these 3" springs today (RR4-2) - however I noticed that the bottom of the front springs are flat, like the rear springs. The D2 seat is designed to support a rounded coil... RTE sells these seats: http://www.rte-fab.com/products?page...category_id=12
But I don't have those type of shocks.

Simon/RTE seems to be gone for the weekend.

 

Nevermind- all good

Simon says they work.

 

Simon is correct. I've have two sets of RTE coils with no problems from the seats.

 

Installed them. I went from 21" wheel center to fender on both sides with the TF springs, to 24" left, 23" right with RTE. Steel bumper, winch, dual batt. My rear is 21" w/ RTE springs. I was hesitant to risk messing up an even ride height, so I spoke at length with Simon before installing the fronts, and he assured me the ride height would work... clearly not so. I suppose the springs will need a few hundred miles to settle, but with 23/24" front, and 21" rear... that's a big difference.

 

I had to install spacers in the rear with my RTE springs to level the truck. Couldn't stand the driving uphill look.

 

Yeah, I suppose that's the only option! Or 2" front springs. A bit annoying that these aren't level out of the box. Simon sure claims as much. Do you have the RTE spacers? TF no longer makes theirs. I think I need to do the rear panhard conversion before adding any more height in the rear. Simon told me he is "working on something" for the panhard - but who knows when thats going to happen.

Going to run these a few hundred miles and see where I'm at.

Good thing I put in d1 rear spring seats or else I'd be way off

 

Not sure who made the spacers I had in the back. Been years ago now. I liked the ride of the progressive springs just couldn't believe how far off the truck was from level.

I thought RTE was pretty much out of business now didn't realize they were still bringing out new product.

 

Simon bought Rte 3 years ago. He’s very thorough and helpful over the phone but I just couldn’t convince him that I was concerned the rte springs would lift me way more than the terrafirmas, not only are they taller but they’re also stiffer.

anyways, I do like how they drive so far, on pavement. Will take them off-road in the next couple weeks. I should probably do an alignment and also lengthen the panhard.

 

The only alignment that's adjustable that will be off is your steering wheel alignment. Your front end alignment will not change with the increased height.

 

Yeah, the castor is probably way off now. I didn’t mean fixin anything, but nice to know how far off spec the castor is. Simon tried to sell me his castor corrected arms, but I found out they are only 3 degrees as well. Plus his are twice the price for only a modified factory part. The terrafirmas are way beefier.
