Project Description


Higher-level performance! Last Sunday, this Volvo S90 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 15mm (3/5 inch), rear 20mm (4/5 inch), PCD 5×108, CB 63.4 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. What do wheel spacers do? If you would like to bolt up wheels that are made with a bigger center diameter for your car, then wheel spacers can be your most cost-effective option. The hub-centric design makes a snug connection between the axle hub and the wheels, meaning no gap, no vibrations, fewer stress loads and more service life range. Besides, by pushing out the wheels to an ideal distance, wheel spacers give your car a more aggressive exterior and a better aerodynamics body. (Thanks to the owner for providing these pics)

Undoubtedly, the Volvo S90 is an elegant, uniquely luxury sedan that offers an avant-garde design, exquisite interior, comfortable seats, and a modern cabin. It offers advanced technology and lavish features to make the ride more joyful. The Volvo S90 is powered by a supercharged direct fuel injection engine, delivering 316 hp at 5700 rpm as well as 295 lb-ft torque at 2200 rpm. An 8-speed automatic with manual shifting mode transmission offers a smooth, sharp switch and a variable all-wheel-drive system provides engaging handling. Plenty of driver-assistance features are on hand to back up Volvo’s reputation for safety.

Are wheel spacers safe on Volvo S90?

Technically, yes, they are totally safe. One of the essential parts of wheel spacers safety is the material. BONOSS forged lightweight plus wheel spacers applied Forged 6061-T6 Aluminum alloy, which is high strength, great toughness, and good corrosion resistance. And the Black Hard Coat Anodizing process provides the surface with better abrasion resistance, flame resistance and smoother and harder finish protection than regular paint or metal plating. They are manufactured with a tolerance of 0.02mm, which means perfectly fit, no additional force, no annoying noise, less energy loss, less fatigue damage, longer service life.

Why do you need extended wheel bolts?

Any time you run wheel spacers, extended wheel bolts are a must option to properly secure the wheel to the vehicle hub. Without the proper thread length, the stock lug bolts will not allow penetrating the vehicle hub threads completely which can cause car shaking or safety risk. BONOSS Forged Grade 12.9 Extended Wheel Bolts are made by the forged process. The forging process offers lots of advantages over other manufacturing processes for wheel bolts, such as high tensile strength and tough, better wear resistance and higher fatigue strength, elimination of porosity, evenly and tight internal structure, good polishing and finishing surface characteristics.

Additional Information:

  • BONOSS wheel spacer thickness can be customized flexibly, which is compatible with most vehicles. Thus, if you would like different sizes of wheel spacers, feel free to contact us. This Volvo S90 uses front 15mm (3/5 inch), rear 20mm (4/5 inch), PCD 5×108, CB 63.4.
  • The extended bolts are spacer structure design, which effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head. This Volvo S90 uses conical seat bolts. If you would like a set of extended bolts, please ensure the seat type of the bolts is suitable for threading tightly. And, if you don’t know the proper length, you are welcomed to contact our tech staff freely.
  • Each BONOSS product is printed with the logo of “BONOSS”. This offers an easy method to distinguish other fake and inferior products.
