FAQ
What is the 3344?It is a matched Old Man Emu rear coil spring set for the verified 2025-2026 Toyota 4Runner application.
Does it fit earlier 4Runner generations?No. This exact spring set is listed for the current 2025-2026 4Runner application.
What is the spring rate?ARB publishes a progressive rate of 114 and 160 pounds per inch.
How many springs are included?The package contains a matched rear pair.
Are rear shocks included?No. Compatible shocks are selected separately for the vehicle, load, and intended travel.
Will every 4Runner gain the same ride height?No. Final height depends on vehicle configuration, permanent load, accessories, and the complete suspension combination.
Is professional installation recommended?Yes. Coil springs store substantial energy and require suitable lifting equipment, procedures, and post-installation checks.
What warranty applies?ARB lists a three-year suspension warranty under its current terms and exclusions.
Installation Instructions
- Confirm the vehicle is a 2025-2026 Toyota 4Runner and verify permanent rear load, ride-height target, and compatible Old Man Emu shocks.
- Confirm the package label and manufacturer part number 3344 before installation.
- Record ride height and alignment values before disassembly, then support the vehicle at approved lifting points.
- Remove the rear shocks and unload the axle only as directed by the factory and ARB procedures, protecting brake hoses, wiring, and sensors.
- Inspect the spring seats, isolators, bump stops, and mounting hardware; replace worn parts before installing the new pair.
- Install both rear springs in their specified orientation and confirm that each end is fully seated.
- Reinstall compatible shocks, torque all fasteners at the specified suspension position, and verify brake-line, tire, sensor, and body clearance through travel.
- Measure final ride height, complete an alignment when geometry changed, and perform any required driver-assistance calibration.
- Recheck seating, fastener torque, ride height, and clearances after the initial driving interval.

Coilover Springs
Shop coilover springs and application-specific replacement coils at Black Ops Auto Works. Compare Eibach ERS/ERO references, QA1 high-travel and tapered springs, King coil springs, ARB/Old Man Emu load-specific coils and the listed road-car spring sets. Choose dimensions and rate for a custom coilover or the exact vehicle application for a formed replacement spring.Read Diameter, Free Length and Rate SeparatelySpring inside diameter identifies the supported seat/body interface, free length describes the unloaded spring and rate describes its force-versus-compression characteristic. Compare all three. The listed Eibach 0900.225.0350, for example, identifies a 9-inch, 2.25-inch-ID, 350 lb/in ERS reference.The QA1 9HT400B reference instead specifies 9-inch length, 2.5-inch ID and 400 lb/in. A similar length does not make these springs interchangeable. Check end shape, seat engagement, installed height and the complete suspension requirements before comparing replacement brands.Eibach, ...
