No, you can’t fit a Silverado 6×139.7 spacer on a Raptor 6×135 bolt pattern. Even though the lug bolt patterns are very similar, the different center bores might not fit over the wheel hubs. The hub bore on a Silverado is 78.1mm while the center bore on a Raptor is 87.1mm. In this case, a 6×139.7 to 6×135 wheel adapter is the solution. Wheel adapters are very useful for converting the bolt patterns, and center bores, and changing the offset.
Since these Silverado 6×139.7 spacer adapters are installed between the hub assembly and wheels, they will push the wheels out further to get flush with the fender flares. This also provides a muscular and powerful look. It is recommended to keep the top of your tires just slightly inside the fenders, so you don’t get any rubbing. With the correct dimensions, you can use those Silverado wheel spacers with no problems.
Are Silverado 6×139.7 Spacers Safe for Off-roading?
Numerous practices and applications prove that quality brand Silverado wheel spacers are not dangerous. Most wobbling or uneven tire wear issues are blamed on low-quality wheel spacers. Always avoid using these cheap casting spacers. BONOSS forged active cooling Silverado 6×139.7 spacers undergo continuous tons of pressure to form. This eliminates any porosity, shrinkage, and other micro-processes presented in the raw material. Such BONOSS forged active cooling Silverado wheel spacers can undertake more force without breaking.
Aside from the above functions, BONOSS forged active cooling Silverado spacers provide additional advantages. For example, the active cooling technique. Distributed in petal shape, the cooling grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates. The flowing air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system. With the same price as many quality spacers, BONOSS forged active cooling Silverado spacers are more advantageous.
Do I Need Silverado Wheel Spacers on All 4 Tires?
Since Silverado wheel spacers will move your wheels outwards from the corresponding vehicle hubs. If you want to keep the wheels following the same track, it will be better to add wheel spacers on all 4 tires. But it doesn’t mean all 4 pieces of Silverado wheel spacers should be the same thickness. You would have to first check the space on each position. For four aftermarket wheels, 4 pcs of wheel spacers will make them fit perfectly. What’s better, BONOSS forged active cooling Silverado wheel spacers are finished with a textured surface on the sides.
The knurling surfaces can enhance the aesthetics by introducing an attractive pattern to their surface. In addition, the side knurling design eliminates internal stress which contributes to more reliable product mechanical properties. The crisscross knurling pattern enlarges the cooling area which is good for the active cooling effect. When installed, wheel spacers become the connection point of the wheel and hub assembly. Hence, such high-quality BONOSS forged active cooling Silverado wheel spacers won’t disappoint you.
