Apologies - Yes, another levelling kit thread with questions

[Slipshodman]

Ok, ok,
So I know this has been discussed to death in other threads.

I just need a sanity check before I lay the cash down to install the Teraflex 1½ in front levelling kit and Daystar ¾ in rear.
Shock extensions are illegal over here and at this stage I don’t intend on added longer or adjustable LCA’s or trackbar.
My eyes hurt from reading so many threads about it. For reference I have a Australian Spec JT Rubi (max tow style front fenders, not high fenders like in the US)
I do get off road, get her as flexed as I can, that’s what we got it for, but I am not in the position for a full lift at the moment– Currently running 33’s, going to 34’s when my next tyre set is due

Anyway, I am expecting after install for

• It to be a little more twitchy at freeway speeds due to slightly lower caster but not excessive.
• The front axle will shift sideways half inch or so due to the track bar angle change, but wont affect the vehicle tracking on the road (not crabbing)

The few questions I have that I can’t seem to find an answer for (or I just can’t get my head around)

• Due to the 1in bump stop extensions in the Teraflex front levelling kit – will I lose 1in of shock travel ?
• If I added the Teraflex Falcon Progressive bump stops that are 1½ in longer than stock would I not fit the bump stop extensions from the levelling kit – or because of the compression rate of the progressive bump stops I would still need them (https://teraflex.com/jt-progressive-bump-stop-kit-front-rear-0-4-5-lift.html)
  • If adding them would work for the front (without using the kits extensions) , if I added the rear Progressive bump stops would I actually loose travel due to there additional length over stock (as the spacer is only ¾ inch – the progressive stop 1 ½ inch longer
• I have the LED headlights etc- the manual states the headlights are self levelling – so do I assume no adjustment is required after the spacer install ?

I could guess the answers but that is when things go sideways
I am mechanically savvy but definitely not a mechanic so will be getting someone local to install for me (not a dealer)
Any guidance in appreciated

Cheers

The TeraFlex spring spacers effectively make your springs longer, so whatever extra length in spring/spacer you add, you get that much closer to the max extended length of your shock. In this case, you add 1.5" spacer, your shock is always going to be 1.5" more extended than normal and would limit out quicker when extending. This is why you add shock extensions to match any spring spacer additions or swapping to taller springs.

The TeraFlex progressive bump stops are longer than OEM, but also softer (more compressible). I'd imagine once they're compressed, they're matched to what the OEM bump stop would be compressed, so you would still want to add the bump stop extension that comes with the spacer kit.

Not sure on the headlights, but if they say they auto adjust/self-level, you shouldn't need to manually adjust them after any lift. Cool feature if they do it automatically.

Yeah, pretty cool feature , our other 2017 Toyota has them also
No mechanics around the headlight them selves for adjustment , I hadn't realised till I had her apart adding a light bar then checked through my build sheet

I get the shock is 1 1/2 inch out of its original range , but would the bump stop extensions stop over travel - from the otherside of the axle, not sure that explains my thinking but as the shock extends on the driver side, the passenger side should hit the bump stop extension before over travel ... Correct ?
That is why I was thinking I would lose 1in of travel as the bump stop extensions in the kit are 1 in.
I don't believe shock extensions are legal here so cannot use them to keep the shock travel in its normal range
