What Dynamic Seal and Gasket does

Dynamic Seal and Gasket (legal entity DSG Inc., DBA DSG-USA) is a private aftermarket engine parts manufacturer founded in 1996 in Atlanta, Georgia, and relocated to Sparks, Nevada in 1999. The company designs and produces premium replacement components — including gaskets, hydraulic seals, pistons, piston rings, cylinder liners, engine bearings, valve train parts, connecting rods, camshafts, and cooling/lubrication components — alongside turnkey engine rebuild kits (In-Frame Kits, Overhaul Kits, Re-Ring Kits) for heavy-duty diesel and natural gas engines from Caterpillar, Cummins, Detroit Diesel, Navistar/International, and Komatsu. Its catalog spans over 30,000 part numbers covering 75+ engine models, and the firm employs a four-phase quality assurance process (concept & engineering, prototyping, testing & validation, final inspection) with proprietary surface treatments such as CG-coated pistons and MP-coated plateau-honed liners under the DSG MPG Proline and DSG PowerPacks sub-brands. From January 2026, DSG is layering Authentic Vision's Holographic Fingerprint serialization and CheckIfReal smartphone verification onto its labels to address counterfeit risk in heavy-duty aftermarket parts.

DSG operates exclusively through a channel-partner GTM, selling only via a global authorized distributor network rather than direct to end users. The company runs wholly-owned operational branches in four locations — Sparks/Nevada (HQ), Ariccia/Italy, Jebel Ali/UAE, and Singapore (DSG Far East Pte Ltd) — and maintains sales offices in 10+ countries including Germany, Belgium, Jordan, Argentina, Colombia, Chile, Costa Rica, and Serbia, collectively supporting customers in 40+ countries. End markets served via distributors and engine rebuilders are earthmoving/construction, on-highway trucking (Class 7/8), marine, mining, power generation, and logging/forestry. Pricing is quote-based and not publicly disclosed; revenue is generated through one-time sales of parts and bundled kits, supplemented by warranty-driven repeat demand (24-month coverage from installation, up to 3 years from purchase). The company is privately held with no disclosed external investors, no parent company, and no IPO signal.

Direct peers

• FP Diesel: FP Diesel manufactures aftermarket engine parts including pistons, cylinder liners, engine bearings, and overhaul kits for heavy-duty diesel applications (Cummins, Caterpillar, Detroit Diesel). Operates through a similar distributor-and-rebuilder channel model targeting the same end-user verticals.
• Clevite (MAHLE Aftermarket): Clevite is a heritage brand within MAHLE's aftermarket portfolio producing engine bearings, pistons, and related rotating-components for heavy-duty engines. Highly comparable to DSG's bearings, pistons, and engine component categories, with overlapping OEM-platform coverage.
• Dorman Products: Dorman is a major North American aftermarket auto parts manufacturer and distributor offering engine and drivetrain replacement parts through professional installers and distributors. Comparable business model — independent aftermarket supplier, channel-driven, broad SKU catalog — though lighter on heavy-duty on-highway.
• Interstate-McBee: Interstate-McBee is a leading independent aftermarket manufacturer of new and remanufactured fuel system and engine components for diesel engines, serving Caterpillar, Cummins, Detroit Diesel, and other heavy-duty platforms. Directly comparable to DSG in product range, customer base (rebuilders and distributors), and global channel model.

Broad incumbents

• Cummins ReCon: Cummins ReCon is the OEM's factory-remanufactured engine and component program offering rebuilt engines, cylinder kits, and long-block assemblies. Overlaps with DSG's Cummins Powerpack product line and represents direct OEM-channel competition for the same customer wallet.
• MAHLE GmbH: MAHLE is a global tier-1 automotive supplier of engine components, pistons, cylinders, filters, and thermal management parts for both OE and aftermarket. Competes with DSG on heavy-duty engine bearings, pistons, and components with substantially broader portfolio and global scale.
• Federal-Mogul (Tenneco / DRiV): Federal-Mogul, now part of DRiV/Tenneco, is a global OE and aftermarket supplier of engine and powertrain components including pistons, bearings, gaskets, and sealing products. Overlaps with DSG across the full powertrain component portfolio and serves the same heavy-duty diesel end markets at much larger scale.
• Caterpillar Reman: Caterpillar's own remanufactured parts program supplies factory-rebuilt engine components for the installed base of CAT engines worldwide. Competes directly with DSG's IFK and OHK overhaul kits via OEM branding, dealer integration, and warranty backing.
• Bosch Automotive Aftermarket: Bosch is a global broad-line automotive aftermarket supplier of fuel injection, diesel systems, and engine components. Competes with DSG in heavy-duty diesel subsystems (notably fuel injectors) and has substantially deeper global distribution and R&D.

Emerging players

• ElringKlinger: ElringKlinger is a German manufacturer specializing in gaskets, sealing technology, and engine components for OE and aftermarket applications. Directly overlaps DSG's heritage gasket/seal business and portions of its cylinder-head component portfolio, especially for European heavy-duty platforms.
