We have an all aluminum 18 inch Grand National reproduction wheel with center cap. Valve stems and lugs included.
Available in 18" x 8" and 18" x 9.5" . Having rebuilt the steel Grand National wheels since 1998 we know all the off sets. No need to call and ask will this rim fit. We own a lot of Buick's as well as drive and use what we sell.
The 8" has 4-1/8" back spacing. The 9.5" has 4-7/8" back spacing.
The wheel is fully powder coated black in the back. The inside outer shell is powder coated black as well. This is for brake dust corrosion protection.
The face is done in the correct factory black powder coat. The paint will not flake off like your factory rims.
One of the toughest things to do when converting from a steel wheel to aluminum is the lugs and caps. What we did was to use a snap ring cap. Think about how much you have spent alone on your factory Grand National caps. The new caps snap in. There is not a metal retainer under the lugs any more.
The opening is 3". You can install a T-Type, Grand National logo or a GNX cap if you want a different look. We have many center caps to choose from. Just search Snap ring on our site.
Aluminum Weight savings? Yes even with 18's you have weight saving over steel. No more rust:
Factory steel 15 x 7" grand national wheel with center cap 28.36 lbs
Aluminum 18 x 8" Grand National wheel with center cap 24.1 lbs Aluminum 18 x 9.5" Grand National wheel with center cap 24.6 lbs.
All rims are tested & speed rated. Crash rating is 145MPH. That is not the speed rating of the rim.
*145 MPH crash rating. Not a Speed rating.
* All our wheels are suitable for Z rated tires.
Most important: When you receive your rims they come with caps,lugs and valve stems.
The tire store will not be able to tack on any expected prices. You will go in knowing the cost except the cost of tires, mounting, and balancing. What other wheel you purchase comes ready to go? This gives you a complete fresh look.
Usually the first question is will it rub?
No the rims will not rub it is always the tire. We have a side shot of a 400 mile Grand National. The GN has 18 x 8 in the front with 255/40/ZR out back is a 18 x 9.5 with a 275/40/18ZR tires. You can put your finger in between the rear tire and frame. We will be adding more of our customers cars with tire sizes and suspension mods. We already seen a GN with 2 drop with 0 rub.
Replacement snap ring center caps are $34.95. We have picked up the 18 x 9.5 by the center cap already. So it would take a pretty good hit to knock it out.
Please send your installed wheel and tirte combo pictures to Sales@Gbodyparts.com.
Thank you for your support.
NOTE: These will NOT fit the factory GN Rims!
INSTRUCTIONS ON HOW TO INSTALL ALL SNAP RING CENTER CAPS:
* When installing your snap ring caps, you will have to make sure the the snap ring is seated correctly. If you install the caps and it spins easily, then the spring is not seated properly. You must remove the wheel and make sure the snap ring is seated in the teeth. Once this is done you will be able to rotate the cap but it will be snug.
We have pictures of us lifting a wheel up in the air from the cap and the cap not coming out.
Reverse the procedure for the removal.
**Please note: you must use alcohol on the center cap to remove the mold release prior to installing the inlays, otherwise they will not form a good adhesion.
