What GB Remanufacturing makes

GB Remanufacturing, Inc. remanufactures and distributes premium gasoline and diesel fuel injection products for the automotive aftermarket. The gasoline line covers more than 1,100 remanufactured fuel injector part numbers spanning over 68,000 vehicle applications, from 1968 through current model years, plus injector seal kits with the o-rings and seals needed to reseal a unit. The company describes itself as the only remanufacturer able to replace internal injector coils, injection-mold new fuel injector bobbins, and wind them to OEM specifications, and its engineers say they redesign around the original failure mode where possible, citing a Nissan/Hitachi injector coil-insulation defect they solved by rewinding with higher-temperature enamel and remolding the connector.

The diesel side is the company's other pillar. GB says it was first to offer a complete light-duty diesel program to the aftermarket in 2007, and its catalog now runs premium diesel injectors, diesel electronics, pumps, and engine components for Ford Power Stroke, GM Duramax, Dodge/RAM Cummins, and Navistar platforms. It was first to market with an aftermarket solution for the Ford Fuel Injection Control Module (FICM) and Injector Driver Module (IDM). Remanufactured injectors are 100% tested for flow rate, spray pattern, and coil resistance, and products carry a 24-month, unlimited-mileage limited warranty. The company also sells fuel injector test and diagnostic equipment developed with its partner Carbon-Zapp. Its 2026 product release, announced in October 2025 ahead of AAPEX, added 75 new SKUs and expanded coverage to more than 212 million vehicles in operation, with the emphasis on its gasoline direct injection (GDI) program as GDI-equipped vehicles age into service bays.

Because the products are remanufactured rather than newly cast or stamped, GB's inbound supply is used cores plus new internal components, and its finished goods reach technicians through the automotive aftermarket distribution channel rather than through an OEM production line.

Ownership and history

Bill and Michael Kitching founded GB Remanufacturing in 1986 in a leased 1,100-square-foot building in Signal Hill, California, initially remanufacturing carburetor choke pull-offs for carburetor rebuilders. As fuel systems evolved from carburetors to port fuel injection to GDI and modern diesel, the company expanded its offerings and moved a short distance to Long Beach, California, where it is headquartered today.

The company remains family owned and operated. Michael Kitching is President and CEO and has been with the business since 1986; Pat Kitching, Treasurer, joined in 1992; and Joe Evert has served as Vice President since 2007. A third generation of the family now holds operating roles: per a June 2026 company announcement, Andrew Kitching is Director of Sales, Ryan Kitching is Engineering Manager, and Delaney Kitching is Marketing Manager. In that same 40th-anniversary announcement the company reported more than 170 team members, more than 1,500 products, and multiple facilities in Long Beach. The company states it is still remanufacturing in the United States.

Certifications and quality

GB describes a quality-first remanufacturing process built on 100% end-of-line testing. Gasoline injectors are remanufactured through a documented 15-step process and tested under multiple operating conditions against OE specifications for flow rate, spray pattern, coil resistance, and form, fit and function; diesel injectors, electronics, and pumps are 100% tested to OE specifications before shipment. Products carry a 24-month, unlimited-mileage limited warranty and are backed by a US-based technical support line and 24-hour rebuild-and-return service on gasoline injectors. GB does not publish a specific third-party quality-management certification on its public site, so no certification claim is asserted here beyond the testing and warranty practices the company documents itself.

Known customers

GB serves the automotive aftermarket, which typically means warehouse distributors and program groups rather than named end customers. One private-label relationship is visible on the public record.

Beyond that documented relationship, GB names Carbon-Zapp as its fuel-injector test-equipment development partner. The company's broader customer list is not published, which is normal for an aftermarket remanufacturer selling through distribution.

Industry standing

GB Remanufacturing was named a 2022 AASA Top Supplier by the Automotive Aftermarket Suppliers Association, the North American aftermarket supplier trade body now part of MEMA, the Motor & Equipment Manufacturers Association. The company positions remanufacturing as a sustainability and supply-resilience advantage, framing its 2026 release around tariff pressure and supply-chain uncertainty in the aftermarket. Company leaders hold aftermarket industry positions: Michael Kitching has been appointed to the CAWA board of directors and the AWDA Manufacturer Advisory Council, and the company has been active in APRA (the reman trade association) and industry Right to Repair advocacy.
