SPECIFICATION:

Spacer Thickness:20 mm

Bolt Shack Length:45 mm

Torqued Down By Hand At:70-80 FT/LBS

Hub Bore:74.1 mm

Number of Pieces: 4

NOTE：

1. Check Your Vehicle Bolt Pattern/ PCD, Hub Bore Size, Thread Pitch, Vehicle fitment compatibility is only a guide.
2. Measure the fender gap and stock bolt length to choose suitable thickness.(For 1 inch or less or special adapters, if the stock studs are longer than the adapters, and the wheels do not have hollow spot in them, you may need to grind, or cut your existing lugs if you don't choose to purchase shorter studs.)
3. PLEASE CONFIRM what you actuall need, wheel spacers or wheel adapters, they are different. Wheel Adapters are used to change bolt patterns in order to properly fit wheels from one vehicle to the hub of a different vehicle.
4. Do not use impact wrench.Please use hand wrench. Recommended to use threadlocker.
5. Returns are only accepted if unused and not  installed.(returns are not accepted if spacers-adapters have been installed to your vehicle).

What are Wheel Spacers?

Also known as wheel adapters, wheel spacers are special components that help create extra wheel track width. They are fitted between the wheel hub assembly and the wheel itself to increase space. Every wheel gets displaced outward by a distance equal to the spacer’s thickness. 

As aforementioned, the primary purpose of wheel spacers is to increase space between the hub assembly and the wheel. It usually is not appropriate for the wheel to be very close to other inner parts like the wheel well. It will lower the driving performance, especially when the tyre rubs against the suspension components when making turns.

Wheel spacers are primarily used in vehicles with wider tyres during custom installation, where the tyres you are installing are larger than the tyres that came with the car. As a result, wheel spacers improve vehicle handling and provide better traction on the road.

STEPS TO PROPERLY INSTALL WHEEL SPACERS:

Step 1: Preparation

Step 2: Loosen All Lug Nuts

Step 3: Lift the Car

Step 4: Remove the Wheel

Step 5: Prepare the Wheel Hub

Step 6: Install the Wheel Spacer

Step 7: Torque the Matching Lug Nuts Tighten using the star pattern as shown below when following the numbers in order.

Step 8: Remount the Wheel

Step 9: Carefully Lower the Vehicle

Step 10: Torque the Lug Nuts to Specification

Step 11: Repeat Steps 1-10 for the Remaining Wheels
