Bulldog Wheel Spacer fitting helper – Important Information

IMPORTANT!

Before installing wheel spacers, thoroughly clean the stud threads on the vehicles wheel assembly.

Preferable using a thread locker, install the spacer and tighten the nuts provided to 95-100 ft/lbs.

Make sure you use the nuts provided to install the wheel spacer, due to the chamfer being correct for the wheel spacers.

When fitting to vehicles with HD drive flanges, a small amount of filling to the inner edge of the wheel spacer may be necessary.

We advise regularly checking your wheel nuts, along with your normal safety checks on the vehicle.

NOTE: Over tightening can cause the following.

(1) Stripped lug nut
(2) Stretched wheel stud
(3) Broken wheel stud
(4) Distorted brake rotor and/or brake drum.

After installing new wheels they should re-torqued after the first 80 to 160 kilometers. This is necessary as wheels may compress slightly allowing their lugs to loosen some of their torque.

Once this has been done please double check the wheel lugs every time 6 months to ensure safety, this should be done in line with your normal vehicle safety checks too.

: Since the thickness of an alloy wheel can differ from Original Equipment wheels, you should verify the amount of threads engaged by the lug nuts or bolts. Refer to the chart (above) to determine the number of turns or the depth of engagement typical for your stud or bolt size.
