Wheel spacers have no issue with your 4WD system in any way. They are metal discs that move the wheels outwards from the corresponding vehicle hubs. The wheels and tires are set apart even further, which in return improves your 4WDs traction and stability. Meanwhile, it adds more clearance to fit larger tires. As long as you use top-quality 4×4 wheel spacers and install them properly, everything is fine.
As manufacturing technology improves, modern off-road wheel spacers are getting stronger, more durable, and aesthetically pleasing. Always purchase from a reputable brand. Genuine brand wheel spacers are trustable because of their quality and performance. Before leaving the factory, manufacturers will do a series of safety tests, such as impact resistance, tensile strength, and hardness. So, you are worry-free about the quality.
Do I Need An Alignment After Installing Wheel Spacers?
Whether you need an alignment after installing wheel spacers really depends. If you haven’t had an alignment in the last 2-3 years, then it is strongly recommended to get a wheel alignment after everything is installed. But, as long as your wheels are aligned well before, you don’t need an alignment after installing wheel spacers. Actually, wheel spacers have nothing to do with alignment.
Consider the wheel spacers as the extension of the hub assembly, if properly set, they even do not affect tire wear, camber, toe, or caster. Wheel alignment is not just an adjustment of the tires or wheels themselves. So, anything suspension-related definitely needs alignment, like shock absorbers or coilovers. However, whether you put wheel spacers on or not, most cars need alignments after about 5,000 to 6,000 miles of driving.
Recommendations for 4WD Wheel Spacers
A set of strong wheel spacers can handle forces better without worrying if they’ll break. Forged 6061-T6 and 7075-T6 aluminum are two popular materials to make 4WD wheel spacers. After the forged process, the strength, hardness, and toughness are greatly enhanced. Besides, you would eventually need hub-centric wheel spacers. They come with middle center rings which are the exact fit for the vehicle hubs. This means you will not have any vibration.
Wheel studs, along with lug nuts, fasten your spacers as well as wheels to your 4WDs. Apart from the wheel spacers, the strength of studs and lug nuts is extremely important. Therefore, it’s vital that you have high-quality studs installed. Grade 12.9 wheel studs are considered to be the top-quality studs in the auto industry. They have a minimum tensile strength of 1220 MPa. The higher the tensile strength, the less chance of wheel spacer failure.
