This bulletin is being revised to add the 2008 model year and another overhead rack kit part number reference. Please discard Corporate Bulletin Number 06-08-42-009 (Section 08 -- Body and Accessories).

Some customers may choose to install an accessory overhead rack kit on the pickup box. When installing any of the overhead rack systems, P/Ns 17802990, 17802462 or 17802461 , follow the instruction sheet supplied with the kit.

Installation of an accessory overhead rack on a customer's vehicle also requires the use of an auxiliary center high mounted stop lamp (CHMSL) that is vertically mounted in the truck bed. This CHMSL, P/N 19165908, is available from GMSPO and should be used in conjunction with an accessory pickup box overhead rack system. Follow the instruction sheet supplied with the part to install this lamp.

All GM Accessories sold and permanently installed on a GM vehicle PRIOR to new vehicle delivery will be covered under the provisions of the New Vehicle Limited Warranty.

For the U.S.

In the event GM Accessories are installed AFTER new vehicle delivery, or are replaced under the new vehicle warranty, they will be covered (parts and labor) for the balance of the vehicle warranty, but in no event less than 12 months/12,000 miles. This coverage is only effective for GM Accessories permanently installed by a GM dealer or a GM approved ADI (Accessory Distributor / Installer).

For Canada

In the event GM Accessories are installed AFTER new vehicle delivery, they will be covered (parts and labor) for the balance of the vehicle warranty, or up to 12 months/unlimited kilometers depending on month installed. For replacement after the new vehicle warranty expires, but within the 12 months/unlimited kilometers coverage, refer to claim type "B" guidelines.

GM Accessories sold over-the-counter, or those not requiring installation, will continue to receive the standard GM Dealer Parts Warranty of 12 months from the date of purchase (parts only).

Only GM dealerships have the ability to file warranty claims for GM Parts and Accessories. Therefore, any warranty claims filed against such parts must be handled by the servicing GM dealership. This includes those parts purchased from a GM-approved ADI (Accessory Distributor / Installer).
