Taking your Trek and turning it into an off-road powerhouse is what we set out to do with our Subaru Crosstrek lift kit. Designed to enhance the off-road performance of Subarus while keeping its plush suspension characteristics, this Crosstrek lift kit increases performance off-road significantly.

With Crosstrek lift kits, we wanted to build the most reliable suspension lift possible, and we didn't want to use inferior products made overseas. Because of this, we chose Bilstein B6 shocks and struts to complement our RalliTEK springs. Shocks made by Bilstein are widely regarded as among the best available. We had found that B6's perfectly complemented our springs after years of testing with our proprietary spring technology.

  • Estimate lift height: 1/2-1 inch with spring options
  • More responsive handling at a higher speed
  • Increased approach and departure angles
  • Extremely Improved Off-Road Performance
  • keeps factory on-road ride quality
  • Increased ability to carry more weight on the vehicle
  • No drilling or cutting, complete bolt-on kit
  • Lifetime warranty

RalliTEK Lift Springs

Our proprietary Subaru springs went through rigorous dyno and real-world testing to guarantee the highest quality and best-performing springs. During our testing with the limited space in Subaru models, we found the linear spring was the perfect solution for the best-performing suspension on the market.

RalliTEK springs are the most advanced springs available for Subaru vehicles. Our exclusive technology dramatically increases the vehicle's performance off-road while increasing the ability to carry more weight or added accessories.

This unique technology improves handling and predictability off-road while keeping the plush on-road ride quality that Subaru is designed for. Our lift springs allow the fitment of larger tires for enhanced stability in inclement weather or tough terrain. In the hills, Overlanding, in the snow, or touring the interstates, there's nothing our springs won't dominate.

Bilstein B6 Shocks and Struts

Developed for a variety of applications, including sports cars, sedans, coupes, trucks, and SUVs, Bilstein performance shock absorbers and struts have been designed to provide improved handling and ride control without sacrificing comfort. Fade-free performance is achieved by using high gas pressure, monotube design with a large diameter shock body.

Bilstein's patented design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise.

The tube of a Bilstein gas pressure shock or strut is fabricated using a special extrusion method. This process achieves an extremely tight peak-to-valley tolerance and maintains consistent wall thickness. Bilstein's seamless monotube design provides superior tube strength while maximizing heat dissipation and shock life.

Additional advantages, based on development strongly influenced by the motorsport industry, include greater stability, better road handling, and accurate steering. This combined with extremely high-quality manufacturing and materials means Bilsteins will last approximately four times as long as the Original Equipment.

Bilstein products are backed by an aftermarket lifetime warranty.

The advertised ride height specified for this product is a measurement taken from a completely new stock vehicle. Your vehicle's actual ride height after installing these springs may be more or less dependent on your vehicle's trim package, add-ons, or additional modifications.

Great investment

Love this kit! I was really hesitant making the investment as I also had to pay a shop for installation. But the result was well worth it! Not only did I gain over 1" of ground clearance for off road use, but my daily driver handling is WAY better than the splashy feel of the OEM setup. Very satisfied!

Thanks for the review!

Amazing Improvement

Installed the Bilstein B-6 Suspension 0.5” Lift Kit for front and rear on our 2018 Crosstrek with only 35K miles. The ride had become awful with the OEM struts and springs. Our vehicle was never abused and rarely driven with more than one person in it, but the ride had become extremely soft and floaty. It was uncomfortable and I believe unsafe. The new Bilstein struts and Rallitek springs are a night and day difference. The ride is perfect now, firm but not harsh. There is no more up and down floating while driving over bumps or dips. The vehicle feels like it’s in contact with the road at all times. I cannot recommend this setup strongly enough and would say no matter how few miles you have on your Crosstrek don’t wait to make this upgrade. The OEM springs and struts are seriously flawed in my opinion. Bilstein B-6 Struts and Rallitek springs transformed our Crosstrek.
