Matthew,
Loving this thread. You're doing a great service to the community. Any help would be appreciated... I'm basically looking to add a couple inches of lift without affecting the factory engineered design and function. Ie: maintain suspension travel, ride quality, etc... Just lifting it a couple of inches. Also without adding any significant additional stress to the components.
I'd prefer it to end up level, it close to level since I'm not looking to raise the front 3.5" to get the raised back up by 2".
I've got an LC LC without premium package. Running 275/70r18 KO3s on stock wheels. I'm not a rock crawler, but like to do light off-roading and want to be confident that I have enough clearance to do moderate trails and comfortably get to more remote locations.
I'm also planning to get full skids and rock slider steps once I'm able to stop spending money on my new house and getting my old house up to snuff to be rented.
Thanks for any advice.
So glad to hear it's been helpful so far and thanks for taking the time to let me know.
I would divide your options up into categories by price. If you're largely happy with how the stock suspension rides and handles, don't fix what's not broken. Option A will get you there. If you want to improve the body control and off-road compliance, move to option B or C.
Option A:
Of course the UCAs can be swapped out with any other version you like, but these are what I would recommend if you go this route. They're $400 cheaper than the Peak version and are excellent quality with a lifetime warranty. Their polyurethane bushings are also very compliant so it won't get jittery like some poly bushings do.
Option B:
These are firmer and more digressive than stock, meaning they provide significantly more compression damping on low speed compression but soften up for harsh impacts and off-road stuff at speed. This allows them to add control and grip off-road without being punishing at all on the street. Most would agree these actually ride better than stock if you don't lift to the very max height.
Option C:
This will provide a similar end result as option B but is an easier install and comes with its own springs rather than reusing the stock ones. These come with fully assembled fronts, meaning no spring compressor is required, and therefore you also get new top hats, etc. These come with their own springs all around so no spacer needed and the rears are fixed at 1.5" lift. These also utilize digressive valving.
Also, technically all of these options
can be run with stock UCAs, but if you're looking for more than about a 1.75" front lift, I would strongly recommend adding them as the caster keeps your steering feeling like it should and you risk being right on the ragged edge of your alignment specs as you approach 2" with stock UCA geometry. I hope this helps!
