Kit Includes:
- Bilstein 6112 3rd Gen 4Runner Adjustable Struts
- Bilstein 5160 3rd Gen 4Runner Rear Shocks
Rear Spring Options:
- 1.5" Lift Rear Springs
- 2.5-3" Lift Rear Springs
- 2.5-3" Lift Rear Springs (Plus Weight)
- 3.5" Lift Rear Springs (Plus Weight)
Options:
- Assembled: Want a ready-to-install front strut? This is the option you need! It is constructed with high-quality MasterPro and OEM-quality stem bushings.
- Front Diff Drop Kit: Corrects 4WD CV angles by lowering your front differential (not required but recommended)
- Upper Control Arms: Replace that worn-out upper ball joint with a brand-new upper control arm and uni-ball design. We offer top brands in the industry!
- Panhard Correction Kit: Corrects your rear suspension geometry after lifting your 4Runner. Our favorite option by far!
- Rear Trim Packers: 10mm Spacers between the springs and the coil bucket. Some people use one on the driver's side to correct any driver-side lean because the driver and gas tank are on the same side. Some also use two (one on each side) to add an extra 10mm height to their rear lift.
- SRQ Swag Pack: This sweet pack includes decals, an SRQ shirt, and an SRQ bottle opener!
Notes:
- Kits come unassembled unless an assembly option is selected. You can reuse your stock tophat and stem bushing/washers to install them on unassembled kits.
- All lift figures are based on lift averages; your setup may vary. We have no control over the total height the lift achieves on your specific vehicle
- 2WD lift heights may vary from estimated heights as the front end is lighter
- Either ASC or OME springs will be used, depending on inventory.
- Equipped with 600 lb springs, this kit is designed for standard setups. For vehicles outfitted with additional weight (bumpers, rock sliders, roof racks, etc.), please reach out to us for alternative spring recommendations.
Frequently Asked Questions
Assembled: Includes the shock, coil spring, and top mount preloaded and ready to install. No spring compressor required—just bolt it in and go.
Unassembled: You’ll receive the components separately. You’ll need to reuse your factory top hats and compress the spring during installation.
Choosing an assembled option saves time and eliminates the need for special tools. It's ideal if you want a quicker, hassle-free install.
If your vehicle has extra weight from accessories like aftermarket bumpers, winches, roof racks, rock sliders, or drawer systems, it’s important to choose springs designed for that load. Standard lift springs are intended for stock weight—using them under added load can result in sagging, poor ride quality, or insufficient lift height.
Our product descriptions include guidance to help you select the correct spring based on your setup. If you're unsure, feel free to contact us and we'll point you in the right direction.
Upper control arms connect your front suspension to the frame and play a critical role in alignment. When lifting your vehicle, stock UCAs can limit suspension travel and make proper alignment difficult. Aftermarket UCAs—like those offered by SRQ—provide improved geometry, more caster, and additional clearance for larger shocks and tires.
A differential drop kit helps correct CV axle angles after lifting an independent front suspension (IFS) vehicle. When your front end is raised, the axles sit at a steeper angle, increasing wear and the chance of tearing a CV boot. A diff drop lowers the front differential slightly to reduce that angle and prolong component life. It’s a small but worthwhile upgrade on most 2–3" lifts.
A Panhard Correction Kit repositions the panhard bar to correct rear axle alignment after lifting a solid axle vehicle. Without it, the axle may shift slightly to one side, affecting handling and tire clearance. The PCK restores proper geometry to keep your axle centered and tracking true. SRQ Fabrications offers the original PCK for the 4Runner, designed for bolt-on precision and trail-tested durability.
DuroBumps are premium progressive bump stops that replace the factory rubber stops. They help cushion suspension compression, prevent harsh bottom-outs, and protect your shocks and frame from damage. Unlike stock bump stops, DuroBumps provide a smoother transition under load—especially beneficial when off-roading or running extended-travel shocks.
Extended brake lines are longer than factory brake lines and are designed to accommodate increased suspension travel. If you're lifting your vehicle—especially 2" or more—it’s important to ensure your brake lines aren’t stretched at full droop. Extended lines provide the necessary slack and help prevent failure during articulation or hard off-road use.
Trim packers are small coil spring spacers used to correct a lean or add minor lift. They’re often installed on the driver’s side to offset “driver side lean” (due to fuel tank, battery, etc.) or stacked to fine-tune ride height. A simple but effective way to level your suspension without replacing springs.
