L462 Lift on Coils

[Aavoxx]

Hello, all. I am hopefully posting in the right forum and hopefully not rehashing an existing topic. A quick search didn't return any results for a previous thread.

I have recently purchased my first Disco! A Disco 5 L462. I initially planned to purchase a Disco with an air suspension, but the combination of price and CPO led me to purchase a vehicle with traditional coil springs. I would like to add 1.5 to 2 inches of lift, or at least level it. As anyone successfully done so and what route did they take if so? Thanks!

LR lists various springs in different class ratings for the D5 in their parts catalog. I think that's the only option at the moment. The lack of low range in the coil version would be more my concern.

A lift on a Disco with no low range seems pretty damn useless. Like driving a giant Subaru

There's a small advantage of having an 8 speed transmission in the D5, 1st gear is 4.7:1 ratio. Compared to a D1 with 3 speed transmission, 1st gear is 2.48:1. I have no idea what the final drive ratio is, but all things being equal a D5 with no low range isn't quite as crippling as a say a D1 stuck in high range. It's still going to suck for anything moderately difficult.

Why no low range with coils?

The SE's come standard with coils. Only way to get a transfer case is to add one of these packs. The SE's with 7 seat pack seem to be pretty rare.

Yah. I'm finding things I thought I could live with for the CPO and the price...I can't actually live with. This one might become my partner's around town car and I'll try again.

If you're quoting the gear ratio for an automatic, then factor in the torque converter multiplication (about 2x off idle).

I've was just shooting for an over simplified comparison. 8 speeds is better than 4 with an overdrive if you're stuck in high range. I'm sure if you took the time you could do all the calculations with diff gearing, torque converter, tire size etc. Maybe I'm wrong when you factor all that in.

But even discounting the torque converter - 2.48 * 3.27 (low range ratio) = 8.1; of course 4.7 is better than 2.48, but it is pretty far from 8.1. Especially since your engine braking is offered by a 2-liter four-banger, not a 4-liter 8.

On this subject - last week in Colorado I was reminded just how great the engine/gear combo is in an early LR4. Going up every trail never needed lower than 2-low, and most was done in the 3-low; going down rarely needed 1-low. In most situations, just putting the transmission in "S" mode made it do everything that's needed without excessive RPM or brake use.
This is a point missed when a new Defender is discussed. HDC is not a solution at all on extended descents spanning several thousand feet - something a fellow in a 2016 LR4 discovered.

I'm guessing the 2016 LR4 was lacking low range? or are you comparing v6 vs v8 engine braking? At least the new Defender comes standard with low range unlike the D5.

No, the '16 LR4 had low range, but the driver (I guess) liked to use HDC.
I don't know if there's a wastegate analog on supercharged V6 - if there isn't, I would guess he should have almost as much engine braking as NA V8.
Turbocharged engines, by design, cannot offer more compression braking because when there's almost no exhaust, there's no boost.
Defender (as all others in the brave new world of turbo 2-liter fours) has to have low range, otherwise it would have no right to be on any steep downgrade.

I’ve become a big fan of the sport mode in the LR4 off road.

It is awesome on I-17 as well - going up or down.
