Fantastic and thanks so much!Why do you need new springs?
If you aren't carrying a lot of extra kg's you can just add 30mm spacers to the original springs to bring your AHC pressures down. If you need more than that try Kings springs for AHC (do a search here).
Hi - Any idea to find other part that possible to use for 100 Series 1999 with AHC? The current available parts can use without active height control only.

SUPER! much appreciated from you insight details!You have these choices:
- Spacers as suggested by @GTV – if sufficient for loads carried, this pre-loads the existing springs to increase spring force on vehicle and it is the least cost and easiest solution,
- OEM Toyota replacement AHC-suitable rear coil springs – some Part Numbers for Australian RHD vehicles and US and other LHD vehicles can be found here: Coil springs for AHC - https://forum.ih8mud.com/threads/coil-springs-for-ahc.871848/page-9#post-13698208, then from Thailand suggest use VIN and explore websites for Megazip (Singapore) , Partsouq (UAE), Impex (Japan) for a good deal, also check out delivery and any import taxes, duties, etc,
- Airbags inside existing coil springs (AHC-suitable Coil-rite CR5114HP) -- Airbag Man - https://airbagman.com.au/ -- sourced through automotive outlets and eBay -- good when loads are highly variable,
- Replacement King KTRS-79 springs – higher spring rate (130 pounds per inch deflection) compared to OEM (95 pounds per inch), so slightly firmer ride but still acceptable on a lightly loaded vehicle, very good for a built-up vehicle with bars, sliders etc, and/or touring loads and/or towing -- King Springs Automotive Aftermarket Springs - https://kingsprings.com.au/ -- sourced by direct contact or through automotive outlets and eBay,
