Bilstein Front - 24-324359 (2)
Bilstein Rear - 33-313146 (2)
The Bilstein 5100 system is one of the most popular first-upgrades for adventure seekers, weekend outtings, and general stock-upgrades for the 2010-2021 4Runners. Hailed as a jack of all trades, the front adjustable height struts allow for up to 2-2.5" of leveling/lift height using the factory coil springs.
These shocks improve all around daily driver handling and reduce body roll, while offering better offroad handling in moderately tough terrain at slower speeds. While not the softest shock on the block, these shocks are in it for the long haul and very dependable.
Additional spring options are well suited for replacing the factory springs and adding additional lift or weight handling requirements.
- Utilizes factory coil springs to level/lift the vehicle with 4 height settings. Performance coil springs available
- Bilstein's legendary monotube gas design, with digressive deflective-disc valving to improve both daily driver handling and more aggressive terrain performance
- Limited Lifetime Warranty
Fully Assembled Option

The Expert's Opinion
"Bilstein shocks aren't always the softest ride out there, but if you want precision handling, confidence at high speeds, and rock-solid stability under load, they're the best in the game.
They're built to perform. At Shock Surplus, we back every Bilstein we sell – because we know they won't let you down"
Questions? We've got answers
Bilstein shocks make your vehicle respond much better than stock shocks. Are they super soft and squishy on the road? No. They give you confidence because your truck or SUV reacts exactly how you expect when you steer or brake. That’s why we say 'Confidence through Control.' If you like having more control and a sportier feel while driving, Bilstein is the right choice. But if you want the same or more comfort than the soft factory shocks, we can recommend other options.
Bilstein 5100 shocks can’t be adjusted for stiffness or rebound. But on some trucks and SUVs (like the Tacoma, F-150, or Tundra), they can adjust the front ride height. This lets you reuse your stock coil springs and still lift the front of your vehicle by up to 2.5 inches, depending on the model. Always check the product details for the exact fit on your vehicle.
Click the 'Select Your Vehicle' button above the 'Add to Cart' button to make sure the shocks fit your exact vehicle. If needed, the site will send you to the right shocks for your ride. If your vehicle has been lifted, use the dropdown menu to pick the correct lift height. For example, if you have a Rough Country 6-inch lift kit, choose Front 4–6" and Rear 3–4" (the rear is usually smaller than the front). Still not sure? Our sales team is happy to help.
Bilstein shocks are one of the most durable and reliable shocks manufactured here in the USA. German engineering mixed with extreme abuse testing has resulted in a shock absorber that is designed to last 100,000 miles or more. We stand behind every Bilstein shock we sell and offer an expedited warranty process for any issues surrounding your purchase from Shock Surplus.
