Quick Summary: When air bags or AHC pumps fail on older models, owners face a crossroads: pay for expensive OEM repairs or perform an “AHC/Air Delete” by converting to traditional coil springs.
When to Repair (Keep the Air/AHC) #
-
Use Case: You primarily drive on tarmac and value the “Lexus” ride quality above all else.
-
Benefit: Auto-leveling when carrying heavy passengers or luggage.
-
Cost: Higher long-term maintenance.
When to Convert (The OME/TJM Route) #
-
Use Case: Serious off-roading, heavy towing, or high-mileage ownership where you want “set and forget” reliability.
-
The Conversion: We remove the bags/hydraulics and install heavy-duty coil springs (like Old Man Emu or TJM) and matching shock absorbers.
-
Benefit: Increased payload, better off-road ground clearance, and zero risk of the suspension “dropping” in the middle of a safari.
Associated Service: [SUSP-LFT-KIT] Lift Kit & Coil Conversion Pro Tip: Converting to coils will usually trigger a dashboard warning light. We include a “bypass resistor” or electronic reset in our conversions to keep your dash clean.
