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 Bilstein's 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.

Customer Reviews

Based on 5 reviews

I’m very pleased with this purchase from Rallitek. They are suspension parts. Parts are top quality, and Subaru outback has a better quality suspension than it did before.

Great performance upgrade for overloaded outback

We have a roof box and bikerack and when we were loaded up with the kids it was sagging pretty bad. I wasn't looking for a lift but for something to handle the weight better. The B6 struts and 1/4" lift springs are much better at supporting the load. Sits at a more stock ride height when fully loaded. When not loaded it sits maybe a 1/2" higher than it did before. I like the ride quality improvement – feels more supported in cornering and but not too bumpy. You do feel some of the smaller bumps more but nothing that bothers us. Thumbs up.

Thank you for your review! We are glad to hear that our Bilstein B6 Suspension Lift Kit has provided a great performance upgrade for your overloaded Outback. We understand the struggles of having a roof box and bike rack, and we are happy to know that our product has helped with the sagging issue. We appreciate your feedback on the improved ride quality and cornering support. Thank you for choosing our product and we hope it continues to enhance your driving experience.

All good but the front strut mounts

This set of struts makes our 2017 Outback ride better than new! Only trouble I had involved the front strut mounts. They wiggled and had a good amount of play in the bearing even though they were brand new. Replaced them with Subaru strut mounts and all was as it should be. I’m sure they wouldn’t have failed but the slight wobble noise would’ve bothered me to no end. I reached out to Rallitek about the issue and they had no solution other than “run them- they won’t fail”. For this price you should be getting a OEM-or-better quality with all of the parts, in my opinion. Expect to pay another $100-$200 for strut mounts on top of this kit if you want it to be entirely noise-free. Otherwise, a great set of struts!

Thank you for your feedback and for choosing our Bilstein B6 Suspension Lift Kit for your Outback. We apologize for any inconvenience you experienced with the front strut mounts and appreciate you taking the time to replace them with Subaru strut mounts. We will take your comments into consideration and work towards improving our product to meet the highest standards. Thank you again for your support and we hope you continue to enjoy the improved ride of your vehicle.

200 mile on road review

Should have come from Subaru with this suspension. Slightly firmer ride. Ride height looks great with stock tires. Handling feels sportier fun to drive. Rear end does not sag with 400lbs of weight. I did not give 5 stars because I have not done any off road travel. Very satisfied with RalliTek kit.

Thank you for taking the time to leave us a review. We are thrilled to hear that our Bilstein B6 Suspension Lift Kit has exceeded your expectations and improved your driving experience. We hope that you continue to enjoy the sportier handling and improved ride height. Don't hesitate to reach out to us if you have any questions or concerns.
