MT-4010 Super Stock Rear Springs
Stock Height | Lexus GX470 / GX460 | FJ Cruiser | 4Runner 4th & 5th Gen
FREE SHIPPING – Lower 48
High-performance stock-height rear coil springs engineered for Prado 120/150–based vehicles where OEM replacement springs are no longer sufficient.
The MT-4010 Super Stock springs are custom manufactured in the USA to Toyota Prado 120/150 specifications to retain factory ride height, geometry, and comfort, while incorporating a +5% increased spring rate to address the real-world weight and age-related sag common to Lexus GX platforms.
Unlike generic stock replacement coils, Super Stock springs are designed to restore proper rear suspension performance without lifting the vehicle or compromising ride quality.
Why Super Stock?
Most GX470 and GX460 vehicles—especially those with aging OEM springs, mild rear cargo weight, or added accessories—need slightly more spring rate, not more ride height.
- Improved load control
- Reduced rear sag
- Better suspension response
- OEM-like ride quality
Super Stock springs are ideal for daily-driven GX/FJC/4Rs that see trail use, travel, or light overland loads, without committing to a lift or heavier-rate suspension.
Construction & Manufacturing
Built from high-quality silicon spring wire, each spring is precision wound, shot-peened and scragged to stabilize the spring rate and reduce long-term sag. A zinc primer is applied before receiving a durable black powder-coat finish for corrosion resistance and extended service life.
