GBodyParts Announces Grand National ALL CHROME 15-Inch Aluminum Wheels

Well, after several years we have finally have in hand the first set of production run Grand National aluminum wheels CHROMED.

Lets get down to what we have here. We have an all-aluminum Grand National reproduction wheel, center cap and lugs. The pictures will say the most but this is the detailed information.

Available in 15″ x 7″, 15″ x 8″ & 15″ x 10″. 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 back spacing on the 7″ rim is the same as the factory, 3.75″ 8″ has 4″ back spacing. Perfect if you want to run 8″ all the way around. The 10″ is 4.5 back spacing. We know and have proven for many years on our cars, that if there is anymore back spacing, the tires will rub.

If you like the inserts black, they can easily be painted.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 in 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, anymore.

The opening is 3″. You can install a T-Type or a GNX cap if you want a different look.

We will show a picture of the rims below with a factory style 8″ rim so you can do some comparisons. One thing I made a tough design decision on was to get rid of the inside lip that is on the steel wheels. It may of had a purpose but the only results we found were for it to collect rust & dirt. The water was trapped in this groove. I eliminated that. It looks a lot cleaner.

Ok, why? Aluminum Weight savings, and no more rust. Lets talk about weight:

Factory steel 7″ grand national wheel with center cap 28.36 lbs
Aluminum 7″ Grand National wheel with center cap 17.76

Factory style steel 8″ grand national wheel with center cap 29.76 lbs.
Aluminum 8″ Grand National wheel with center cap 19.02

Factory style steel 10″ grand national wheel with center cap 33.33 lbs.
Aluminum 10″ Grand National wheel with center cap 19.60

The 10″ wheel has been modified to accept a 275/60/15 drag radial for ease on mounting. If you ever installed one of these on a 10″ rim you know it takes some effort.

All rims are tested and speed rated.

*145 MPH crash rating. Not a Speed rating.

* All our wheels are suitable for Z rated tires.
