Dobinsons 5th Gen T4R Suspension options - from Exit Offroad

Here is a parts description of the springs from their catalog. You'll just need a metric conversion app for lift height in inches.

they will need more than a conversion app, they'll also need access to your computer

Mike has been really helpful trying to help me pick out my setup. We have decided on C59-300 springs for the fronts paired with the LT front shocks and C59-325 rear paired with the standard rear struts. This will give me the desired 3"f/2"r lift. I will post my review/thoughts once I receive and install everything. Thanks Mike!

Yeah, I'm stoked for you.

We also sell new strut caps and can assemble the struts here and ship them assembled so you can do a driveway install. Add $140 for the new caps with assembly to the price, $70 per side. It will save time for you and labor of having to disassemble the old units to just get the cap off.

I had forgotten that our LT struts have a taller coil seat, so with a 2" Coil, it will give 3" of lift. Essentially adding anyone's coils on these struts will give 1" extra over whatever their height is. I'll make a side by side comparison photo here soon and post it up so you can see it.

I've had their rear variable rate 400lb coils sitting under my piano for over a month .. I'll try and get these on this weekend and report back. I will say Mike was super easy to do business with and was very responsive to my inquiries.

Stupid question then:
If you can get a 3" lift with the 2" (C59-300) springs and the LT front struts(GS59-574), with the 3" springs (C59-448) isn't going give a 4" lift will it?

Yes, your math is correct. It's not recommended to do that though unless maybe you have a 2WD and don't have to worry about CV's and such.

The 448 coils should be on the GS59-700 struts to give 3" of lift. Or you could use the 300 coils on the GS59-574 struts to get 3" of lift that way (2" coil + raised height coil seat = 3" lift). If you put the 448 coils on the LT struts, but added weight (bumper/winch), then it would drop down the height and you'd have a comfort ride coil still but holding the weight. That's what we're running on our company T4R right now, and with the bumper and winch (180LBS or so) we're at about 3.25" lift with those 448 coils.

Or you could put the 448 coils on someone else's long travel struts, like the Bilstein 5100's. There's a guy on here just about to do that

Perfect. Makes sense. thanks.

Would bump stop extenders be necessary on a 2" lift ?

No, as long as you only use the 2" shocks. Those bump stops are needed for the 3" long travel shocks to make sure they don't compress too far.

Thank you sir. Nice talking with you today.

hey mike, emailed you a question last week but I'll just ask here...are the 675V rear coils side specific? Do they have a 15mm difference in height like the other coils?
Thanks!

Sorry man, we had some email server problems last week and a bunch didn't come through apparently. The coil tags will say LH and RH is they are side specific on them. I'll check the guide tomorrow to see if those are even or not. I'm pretty sure those are and only the KDSS coils are offset.

Edit: Those C59-675V are equal height. Each of the coils would say a LH or RH if they are side specific, and if not, they would have identical tags on them.

 

[Crikeymike]

Did someone say they needed their struts assembled?? Busy morning...

 

[RIjon]

Couple of those are mine :rockon:

 

[Jamart5]

So any pics of lift installed yet?

 

[deedubb]

I'm getting close. All parts are here (UCA's, tires, wheels, springs, struts/shocks, diff drop etc). Going in today for a BMC then need to find a decent day to put it all together. Getting excited!

Hey holler if you want some help...i'm not far from you, just over here in north Denver, near Arvada.

I will never turn down some help
Beer is on me!

A customer from out of the country sent this in this morning.

It has these parts installed:
C59-300
GS59-700
C59-325
GS59-701

 

[Simpleman74]

C59-325 - Stock rear end load, 1.75 to 2" lift

how much for a pair shipped to Tampa
