Aging second-generation Toyota 4Runners can develop a noticeably low rear stance, especially when loaded with passengers, camping equipment, or accessories.

Before purchasing parts, owners should distinguish spring-supported ride height from shock absorber damping. Replacing the wrong component may leave the actual problem unchanged.
Why Does a 1990–1995 4Runner Sag?
The second-generation 4Runner uses rear coil springs to support vehicle weight. Aging or fatigued springs, constant cargo, heavy rear accessories, or damaged suspension hardware can contribute to a low rear stance.
A vehicle may also look rear-low because the front suspension is set unusually high, so inspect its overall posture rather than guessing from a single measurement.
Will New Shocks Fix Sagging?
Ordinary replacement shock absorbers control suspension motion; they do not provide the spring's primary static support.
New shocks can restore damping when the originals are worn, but they will generally not fix a low rear ride height caused by fatigued springs or excess load.
When springs are the issue, replacing only shocks does not address the root cause.
Factory-Height vs. Raised Rear Springs
A factory-height spring is the direct route when the goal is returning an otherwise stock vehicle to its original stance.
Raised replacement springs serve a different purpose: they can improve the vehicle's ability to maintain a desired raised stance under their intended load.
If a truck has already sagged below its original height, the measured gain after fitting raised springs can appear especially large.
Old Man Emu Medium and Heavy Springs
Preserve Rad offers ARB Old Man Emu Rear Coil Spring Pairs for 1990–1995 4Runner.
The medium-load option is intended for vehicles without major permanent rear equipment. The heavy constant-load version is intended for a sustained added load, not simply anyone who wants the stiffest spring.
Using heavy constant-load springs on a lightly loaded truck can result in a higher or harsher rear suspension than desired.
These OME springs are raised replacements, not stock-height replacements.
How Much Lift Will You Get?
The product family targets approximately 50 mm (about 2 inches) of rear lift at the appropriate intended load. Actual height varies with the vehicle's starting condition, added weight, and supporting suspension equipment.
A worn vehicle may measure a larger height increase relative to its sagged condition without the new springs exceeding their nominal design.
A heavier spring also does not increase the vehicle's factory payload, axle, or towing rating.
What About Front Suspension and Alignment?
The 1990–1995 4Runner has torsion bars in front and coils in the rear.
Rear lift changes the whole vehicle's stance, so the front suspension, alignment, available travel, and other geometry should be considered in a complete suspension plan.
The springs cannot make an incorrectly configured front suspension suitable for the new stance.
Choosing Matching Rear Shocks
Stock-height shocks may not offer suitable travel after a suspension height change. Verify the selected damper's mounts and suspension operating range.
For the raised OME arrangement, Preserve Rad also lists Old Man Emu Nitrocharger Plus Rear Shocks.
Spring load preference and the intended height should be evaluated together with damper compatibility.
Frequently Asked Questions
Are OME rear coils only for lifting?
They are raised springs, but owners also choose them to replace tired coils and support added rear equipment. The lift is still a real part of the result.
Will heavy springs prevent sag permanently?
They are appropriate only when matched to the sustained load. Excessive spring rate may reduce comfort.
Do heavy springs increase my legal vehicle payload?
No. The manufacturer's ratings remain unchanged.
Our Recommendation
Inspect the original coils and actual rear loading before deciding. For a pure factory-height restoration, choose correctly specified factory-height springs. For an intentionally raised stance with normal passenger and cargo use, consider the OME medium-load configuration. Reserve heavy constant-load springs for sustained additional weight.
