Product Description
TruHart StreetPlus coilovers give the 1990-2000 Lexus LS400 a lower ride height and a firmer, more controlled feel without giving up the travel needed for normal street driving. The twin-tube design is built for daily use, weekend cruises, and occasional autocross or spirited driving.
Ride height is adjusted at the lower mounts, allowing the LS400 to be lowered without changing spring preload or reducing available shock travel. The kit includes aluminum upper mounts, zinc-plated shock bodies, powder-coated lower mounts, and anodized hardware to help hold up against corrosion. Damping is preset, making this a straightforward coilover option for LS400 owners who want adjustable height without having to tune damper settings.
Popular Suspension Upgrades for Your LS400
- Megan Racing front camber and caster control arms for Lexus LS400 allow the front alignment to be corrected after lowering.
- Megan Racing rear upper control arms for Lexus LS400 provide rear camber adjustment for a lowered LS400.
- Megan Racing rear toe arms for Lexus LS400 help set rear toe on compatible 1995-2000 models after suspension changes.
Before You Buy
The TruHart StreetPlus kit is a fixed-damping coilover for LS400 owners who want adjustable ride height without stepping into a more expensive adjustable-damper setup. Upper mounts are included, and the lower mounts let you set the car from roughly 1.5 to 4.0 inches below factory height while keeping spring preload separate from ride-height adjustment. Once you have the LS400 sitting where you want it, get an alignment. Cars set low may need adjustable camber and toe arms to bring the alignment back into spec.
