Project Description


Last Thursday, this Jeep Wrangler JL installed BONOSS Forged Active Cooling Wheel Spacers, front 30mm (1.2 inches), rear 38.1mm (1.5 inches), PCD 5×127, CB 71.6. Why do wheel spacers do? Many off-road vehicle owners use wheel spacers to widen the track width and gain stability while rock crawling. By pushing out the wheels, you can gain a certain amount of clearance for bigger wheels instead of rubbing against the fender, improving balance performance. Having your wheel brought out ideal distance allows for mounting larger brake calipers without wheel scratching. These spacers and bolts are specifically engineered to give your car better cornering, aerodynamics, and exterior. (Thanks NO.400 for providing these pics)

The Jeep Wrangler JL is a great powerful sport off-road vehicle. It’s one of the best off-road vehicles you can ever found, and it is a mix of tough, adventuring spirit with luxury and top-class experience. Its muscular power system, smooth-shifting transmission, and a plentiful list of functions furthermore boost this vehicle’s charm. The plug-in hybrid 4xe and the fire-breathing, the DOHC 24-valve V-6 engine, delivering 285 hp at 6400 rpm, 260 lb-ft torque at 4800rpm, an 8-speed automatic with manual shifting mode transmission, offering smooth, sharp switch. Easily deal with various off-road situations.

Why you should use forged wheel spacers?

The main manufacturing processes of wheel spacers on the market are forging and casting. Even with the same material, wheel spacers behave with different mechanical performances by different processes. Considering the requirements of strength, then casting wheel spacers would not be suitable for off-road rides anymore. Most cheap spacers are made from low-grade aluminum. These low-quality casting spacers are not strong enough and will be deformed and destroyed under intense impacts, leading to disasters. In opposite, forged spacers which are machined from billet aluminum (aircraft grade), are quite stronger and higher performance than their cast alternatives. If you need spacers, we recommend you purchase the highest quality ones available to reduce the risk of failure.

What does hubcentric wheel spacer mean?

Off-road is not only a test of powertrain but also a test of wheels for vehicles. When receiving constant impacts, the wheels may get vibration. And one of the reasons for this vibration is that the wheels are not actually central to the vehicle hub. Vibration greatly affects the driving experience, which is also not safe. Hub centric wheel spacers are designed to make a snug connection between wheel and axle hub, ensuring the hub carries the weight of the car instead of the studs or bolts. This allows the wheels are truly central to the vehicle hub, transforming a lug-centric wheel into a hub-centric wheel, meaning no gap between the wheels and vehicle hub and the elimination of vibration. Meanwhile, hub centric wheel spacers also reduce the stress on the wheel studs or bolts, improving service life range.
