The Eibach PRO-LIFT-KIT HD is a pair of rear-only coil springs for the 2025-2026 Toyota 4Runner SR5 4WD with the non-hybrid 2.4L turbo engine. The manufacturer says its lift line uses the same championship-winning off-road racing springs found in its competition products. The HD version is built for trucks that carry extra rear weight, such as a rooftop tent or swing-out bumper. The manufacturer describes the HD springs as offering higher load capacity, less sag under load, and better stability. A standard rear lift spring lacks that extra rate, and a spacer lift adds no real load support, so this kit is the better choice for a loaded rear. Search terms buyers use include 2025 4Runner SR5 HD rear springs, 4Runner rear sag fix, and 2.4L turbo non-hybrid rear lift springs.
Fitment is limited to the non-hybrid 2.4L 4WD trims. The manufacturer's listing covers the SR5, TRD Sport, TRD Off-Road, and Limited 4-door 2.4L Turbo non-hybrid 4WD models. The springs must be paired with Eibach Pro-Truck Sport Rear Shocks, so budget for shocks if your current units are not those. Lift depends on load. The manufacturer warns that running the springs below full-load height produces poor ride quality. Installation is a rear-axle job. Owners on user forums recommend lifting both sides, setting jack stands, and lowering the axle evenly, since working one side at a time causes problems.
Yes. The manufacturer specifies that these springs must be used with Eibach Pro-Truck Sport Rear Shocks.
The manufacturer's listing gives rear heights with 1,000 lb of added weight, and it notes that exact lift varies with the vehicle's package and weight distribution. Confirm the figure with the manufacturer before ordering.
The manufacturer advises running them only at full-load height, since too much lift causes poor ride quality.
Owners on user forums describe the rear swap as pretty straightforward, with the job requiring jack stands and two jacks to make it easier. Follow the manufacturer's sequence and keep the factory isolators and dampers, since Eibach's install sheets for related 4Runner springs call for reusing them and for installing with the logo facing up. Owners also suggest retightening all bolts after the first 500 miles. After the install, Eibach's sheets for related 4Runner springs advise checking wheel alignment and fender and brake-line clearance.
