Modified my GX470 for offroading in May 2021 and the first fabricator used ToyTech RCC2.0 HD springs
Unfortunately, the weight of my my modified 2005 Lexus GX470 with heavy duty bumper, spare tire carrier and self-recovery gear still had too much droop after removal of the ToyTech HD springs
In September 2023, new fabricator installed OME2896. No change in the droop, so we swapped out to the OME2898 being offered for sale. Still, too much droop.
In April 2024, installed the final solution - a set of OME2899 which are currently on my vehicle and NOT being offered for sale.
Pro Tip to save you $$$. The OME2899 are for the GX460, are taller and are heavier than what you can buy for the GX470, but they fit! They are rated 220 lbs heavier than the heaviest rated GX470 spring.
