The Scoop on Wheel Billet Adapters and Spacers – Performance Plus Tire .6 There are a batch of theories floating about about the consumption of steering wheel adapters and spacers and their safety. here are a few facts and thoughts that will help you make your decision whether to use them or not .

Wheel Adapters

There are 2 primary uses for adapters :

  1. The first and most common use is to change the bolt pattern. Adapters are available that will change a 5-4.50″ to a 5-4.75″ or to a 5-5.00″, or the other way around. There are several companies that make adapters that can offer about any combination within reason. There are also adapters that will change a 4 hole pattern to a 5 hole. Changing a 5 hole to a 6 hole is pretty much out of reason. The drawback to using adapters is the thickness required to make them work properly. The minimum thickness required is about 1.125″ (depending on the length of your studs). This will move your mounting surface out 1.125″ and could cause some fender clearance problems.
  2. The second use is if you need to move your wheels out from the existing mounting surface. Adapters are available that have the same bolt pattern (i.e. 5-4.50″ to 5-4.50″). Adapters are the best way to accomplish moving your mounting face out. Adapters can allow you to move the mounting face from 1.125″ up to 2.500″. Anything over 2.500″ would require a little engineering, design and load calculation.

How they work:

Adapters are machined with a P.C.D. drilled with lugworm holes ( 60 deg. conic seat ) ( see TECH Stuff 4 ) to accept an open end lugworm testis. There are studs inserted in another P.C.D. between the lug holes ( see drawing ). The adapters are installed on the vehicle with stuff nuts and tightened to the proper torsion ( TECH Stuff 4 ). Make certain the fomite stud or lug nuts do not extend past the mounting open of the adapter. The adapter becomes an extension of your master mount open. then mount your roulette wheel and tighten it to the proper torsion .

Spacers have gotten a bad rap over the years. Some of the stuff is well deserved, but for the most part, spacers are not a bad thing and if used by rights are a identical useful creature to make your wheels fit properly. A spacer over 0.313″ ( 5/16 ) is not recommended. That makes it baffling when you need to move the wheel out from 0.313″ to 1.125″. That ’ randomness no world ’ s down ( between a spacer and an arranger ). Oh well .
There are three basic rules to consider when using spacers ;

  1. Always make sure you still have proper thread engagement of your lug nut and stud (TECH Stuff 4) after you have mounted the wheel on the vehicle with the spacer.
  2. Choose a spacer that has a lot of mounting surface. There are spacers being offered that are a “fit all” (4, 5 & 6 hole) type. These look like a piece of Swiss cheese and work about as well.
  3. Also make sure the material is adequate (billet aluminum is best – pot metal is worst).

Adapters and Spacers can be identical handy tools that can help you get barely the look you ’ re trying for with the wheels on your Rod. When used by rights, they are safe and authentic .
