Product Details
The Bilstein B8 6100 rear shock is designed for drivers who want more thermal capacity and damping control than a traditional light-duty replacement shock. Its large monotube body and digressive piston move more oil and shed heat efficiently, helping the suspension stay consistent through rough roads, loaded travel, and repeated off-road impacts.
Compared with the 5100, the 6100 is aimed at heavier use and drivers who place a higher priority on durability and sustained control. It remains a direct-fit, non-adjustable solution, making it a straightforward upgrade for daily-driven vehicles that also see overlanding, towing, or demanding trail use.

CUSTOMER REVIEWS
Bilstein Upgrade
The Bilsteins were purchased to replace some worn Rough Country N3s. The installation was straightforward with no difficulties. I also replaced the steering stabilizer with the matching one from Bilstein. The overall ride improvement feels solid. It is firm but smooth.

Making the Greatest Truck Even Greater
Put these on my 2014 Tundra. Noticeable difference especially at high speed and washboard gravel. For under $1000, can't go wrong
Verified Buyer
Like a new truck.
I didn’t realize how bad my suspension was till I put the Bilsteins on. Had Ranchos and these are sooo much better. Quick shipping. Decent price. Great product.

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.
