Rancho RS9000XL Review

Let’s start the review with the exclusive model from Rancho, the RS9000XL. It features a graphite-filled piston, which makes it highly responsive for driving. It is further enhanced with the tri-tube body design that ensures oil moisture and air are kept to a minimum. 

The bigger piston and the extended body complement the nine positions turning technology, making this shock absorber great for even mountain roads. The best part is that the nine position turning technology is adjustable. 

The Rancho RS9000XL has caught the attention of many ever since it hit the market. The nine-setting adjustability is the highlight feature that allows for both off-road and on-road driving experiences. As for installation, you don’t have to go out of your way. Some knowledge combined with the right tools, by following the installation guide, will be enough. 

The nine different settings are divided into three different categories. The first three settings have been optimized for the off-road driving experience. The next three settings are designed for the average daily driving experience. Finally, the last three settings are specifically made for any kind of towing in case you need it. 

You can use the user-friendly dial to adjust the settings. It is as simple as it can get; simply turn the dial anti-clockwise to soften and in the opposite direction to harden. It is an incredible shock absorber with some of the best technology available on the market currently. But which one is better when it comes to Rancho RS900XL vs. Bilstein 5100? Let’s look further!

  • The extended nitro carb rod supports both on and off-road driving.
  • Maximum fluid retention thanks to the tri-tube design.
  • Enhanced durability is backed by a lifetime warranty.
  • Nitrogen gas for optimum results.
  • It has a large body that allows for a cooler and more consistent performance.
  • The price may be too high for some people.

Bilstein 5100 Review

The Bilstein 5100 is one of the best shock absorbers for the most stringent towing and driving conditions. It features a ride height adjustable system that adds lots of benefits, which include and are not limited to:

  • Maximum ride
  • Drag-race tuning without external lifting or lowering tools
  • Speed-height adjustment
  • Easy access in all weather conditions.
  • Load adjustment
  • Autocross

This specific model and series from Bilstein is extremely popular due to the versatility and support for most of the aftermarket springs. If you own a Jeep Wrangler, this is what you need to improve the ride’s road manners. It does so with perfection and without any compromise to the ride’s off-road abilities. It is without a doubt a high-end shock absorber that leaves no stone unturned to make your riding experience pleasant.

The Bilstein 5100 offers you better handling over the ride along with increased wheel travel. You can rely on their premium quality to withstand wear and tear for longer, even when off-roading. All materials used in the manufacturing of the Bilstein 5100 are reliable for a consistent driving experience. 

The shocks can easily withstand high pressures measuring up to 12 tons, making them highly durable and reliable for driver safety. Thanks to the excellent build, you also won’t have to spend much on maintenance and repair costs. 

The installation process is no rocket science either. Just follow the instruction manual, and you will be good to go. The best part is that all the tools required for installation come with the package. A lifetime warranty is a plus for drivers looking for a long-term product. 

However, there is a little catch. You might find the Bilstein 5100 shock absorbers to be slightly stiffer than your stock shocks. More importantly, if your ride has higher suspension clearance levels, it might not be able to perform to its full potential. Other than that, it is an incredible product that is easily one of the best performing absorbers for your truck or SUV.

  • Minimized nose dive while braking.
  • High resistance against bumps.
  • Supports 4WD vehicles.
  • Accelerates wheel return.
