Hey everyone, about to buy a 2 inch lift kit, trying to research whether I should go with MD or HD Terrafirma. Ive got an aftermarket steel bumper with winch on the front, a snorkel, and an over landing style roof rack on the top (250lbs - 350lbs I think). I hope to replace the rear bumper with an aftermarket steel bumper as well in the next 6-9 months. On a day to day basis, I carry myself and passengers, a 50lbs tool box, the spare tire, and other small intricacies. I will be off-roading / camping probably 5-10 times before December, starting in August. I use it to tow as well when needed (however not often), and the vehicle will be loaded down with a lot of weight in a month as I am moving to a different city. I’ve been told that it is a truck, and if it rides a bit hard it doesn’t matter, if you are able to tow better/ load it up more when needed, but I would like everyone’s opinions. I am thinking of doing HD for that reason, and since I have added weight like that daily, but any help is appreciated. Thanks!

MY 2 cents.. Don't get Terrafirma..

1" shim on RR to get level.. Med rides WAY too rough for me +100lb front +300lb rear

I think another user switched back to stock and added blocks; worth a read!

I appreciate the advice, regarding my situation, would you get MD or HD in general, regardless of the brand?

I had the TF 2” med duty for 70k miles without and heavy accessories. The shocks didn’t last long at all. The ride was tuff even with 4 adults and two kids and stuff. I’ve got 10k miles on Ironman med loads with KYB HD shocks. Rides as nice as my stock D2 does. We will see how long everything lasts. Good luck with the choice.

My 2 cents. Go as soft as you can so Med. Reason why is it won't always be loaded down so much. And extended bump stops/better shocks will do more than just stiffer springs..

Pretty sure a lot of my roughness was from swapping to poly bushings everywhere as well. But the TF springs were all different lengths and location specific, yet leaned more than my stock springs did.. I was NOT happy, I called TF and they said "we got some 50$ 5mm spacers we sell for this"..

WTF, RL spring is about an inch longer than RR and Guess which way it leans???? To the right... So if they had just made the rear springs the same... IDK I was NOT a happy camper after lifting my Rover, had to do caster arms, new driveshafts, mods and mods, and now it rides like a Honda 2" off the ground..

I put a TF on my D1 did castor correction bushings. With no extra weight it was way more than 2 inches. Its settled after a year.

I forgot about the lean. It was a lot with TF springs. Hated it.

My first Disco spring replacement was from worn out stock to TF MD. It was an improvement, but anything would have been. A few years later I replaced TF with Old Man Emu springs paired with Bilstein shock absorbers. Night and day difference. I'm never going to spend money on TF again. Learn from the experience of others, save up some extra scratch, and buy the OME. You'll be grateful. Trust me on this. I've been there.

Also, I mixed the spring duties. I put MD on the front axle and MD-HD on the rear axle. Ride quality unladen is good. Ride quality with 800 pounds in the vehicle is superb.

Don't be another victim of Cheapskate Objectivity Paralysis.

Edit: if you buy your OME springs from Expedition Exchange, they will sell you a matched set (i.e. all driver's side or all passenger side) so no vehicle lean after installation. A nice touch I appreciated.

Exactly!! Have OME springs and Bilstein shocks on my RRC. Great combination.

And as you mentioned EE will provide a matched spring set or you’ll end up with the Rover lean!
