anyone have a clue on that ZR4 option???

The Regency SS is most likely a conversion package.

The ZR4 badge was originally on a crew cab S10 that Chevrolet entered into Baja competitions.

I didn't know that GMC was introducing such a truck,unless it's a conversion as well.

If you read closely you'll see that they are both "conversions".

There was a Silverado ZR4 Interceptor conversion in the auto locator about 4 months ago.  Looks like the specs are similar.

When the CC S-10's first came out, I saw a ZR4 badge on one  that had a lift and tires. Made the CC S-10 look alot better with the lift and tires. I don't think ZR4 or SS is a manufactured vehicle yet, just a Conversion or a dealer makeover.
