Wheel spacers are an inexpensive way to improve various characteristics of your vehicle, but it is important that proper care is used during installation to ensure long lasting performance!
Proper Wheel Spacer Installation in Four Simple Steps
- Place wheel spacer over your factory wheel studs.
- Torque our provided nuts to 80 lb-ft in a crisscross pattern.
- Install your wheel over the top of our wheel spacer and torque in a crisscross pattern according to Toyota's specifications:
- If you have steel wheels: 70-77 lb-ft
- If you have alloy wheels: 76-83 lb-ft
- After a week of driving or your first wheel'n trip, remove your wheel and re-check each wheel spacer nut torque.
Why this is important
The reason for this procedure is that our studs and nuts have a higher yield strength than the spacer's billet aluminum body, and a small percent of deformation is expected during normal heat cycling of your brake and spindle parts. For this same reason, aluminum and magnesium wheel manufactures recommend double checking lug nut torque 100 miles after installation.
The important take-a-way is that forces are carried out across the surface contact areas between the wheel, wheel spacer, and vehicle. If the lug nuts become lose for any reason, then forces will be carried through the shear strength of only the wheel studs -- which is far lower -- and will result in stud failure. Keep your lug nuts tight, not only at the wheel but also at the wheel spacer, and you'll enjoy our wheel spacers for many, many years to come!
What about thread lock?
Our opinion on thread lock is that it should not be used for wheels or wheel spacers. Because wheel hardware is expected to lose torque initially, we need the threads to be free in order to double check torque. Marlin recommends just the opposite in fact, which is to use anti-seize. The reason for this is similar to the oiling of cylinder head bolts: A low friction environment is necessary in order to get an accurate measurement of torque. An argument could be made to use thread lock after the wheel spacers are broken in, but what happens the next time your wheels are off and you'd like to double-check your wheel spacer nut torque? If loctite is used then you cannot follow through with proper operational maintenance.
Don't forget that even Toyota does not recommend lug nut thread lock!
