# Argo Generation 1 Transmission Parts Are Now Available **By Ed Pfeiffelman** · 2026-09-11 # **Doc’s Full Bore Outdoor Resurrects Argo Generation 1 Transmission Parts ** If you own a Argo amphibious XTV manufactured between the 1990s and 2007, you already know these machines are engineered to tackle terrain that stops other vehicles in their tracks. Whether you are navigating marshlands in a **Response**, hauling gear with a **Conquest**, or exploring the deep woods in a **Bigfoot**, your older 6x6 or 8x8 is an indispensable workhorse. However, time and rough terrain take a toll. For years, owners of these models have faced a growing crisis: Argo has discontinued critical Generation 1 transmission parts. Fortunately, you don’t have to let your trusted machine rust away in the field. Doc’s Full Bore Outdoor has stepped up to keep your beloved Argo rolling with an exclusive line of Made in the USA, premium aftermarket replacement parts built to the exact high-quality specifications as the original OEM components. * * * ## Argo Gen 1 Transmission Replacement Parts When your transmission gears strip or your shafts wear down, finding replacements can feel impossible for the Argo Generation 1 transmission. Doc's Full Bore Outdoor solves this by manufacturing USA-made, high-durability components designed for a seamless fit.  Doc's offers the following aftermarket replacement parts that the factory has discontinued and are the most popular replacement parts for the Gen 1 transmission: **[34-16A-AM - Gear Idler 13 Tooth w/ Bearing](https://parts.docsfullboreoutdoor.com/products/34-16a-am "34-16A-AM - GEAR, IDLER - 13T w/ BEARING")** **[34-11-AM -  Pin, Dowel .5x3.5](https://parts.docsfullboreoutdoor.com/products/34-11-am "34-11-AM - PIN, DOWEL 1/2X3.5") ** **[34-91AM - Gear, Double 26/33 Tooth](https://parts.docsfullboreoutdoor.com/products/34-91-am "34-91-AM - GEAR, DOUBLE - 26/33T")** **[34-21-AM - Shaft, Input 13/21 Tooth](https://parts.docsfullboreoutdoor.com/products/34-21-am "34-21-AM - SHAFT, INPUT - 13/21T")** **[34-47 - Gasket, Transmission Gen 1/64"](https://parts.docsfullboreoutdoor.com/products/34-47-am "34-47-AM - GASKET, TRANSMISSION COVER 1/64\" THICK - GEN 1")** **[610-80-AM - Disc, Brake - Splined #50-2x13 Tooth](https://parts.docsfullboreoutdoor.com/products/610-80-am "610-80-AM - DISC, BRAKE - SPLINED #50-2X13T")** ![](https://cdn.shopify.com/s/files/1/0955/3153/2597/files/Argo_Gen_1_Transmission_Parts_2.jpg?v=1789131963) * * * ## ## Complete Transmission Rebuild Solutions: Doc's TRK Kits Instead of hunting down individual seals and bearings piece by piece, Doc’s simplifies the overhaul process with comprehensive transmission rebuild kits tailored to your specific Argo transmission generation, a must when splitting the transmission to replace any gears or shafts. ## Argo Generation 1 Rebuild Kit (Part # TRK-400) Designed specifically for the **Bigfoot 6x6**, **Conquest 6x6 and 8x8**, **Response 8x8**, **Vanguard 6x6**, **Vanguard II 6x6**, and late model **Magnum 8x8** this all-inclusive kit contains every high-wear item needed for a total transmission restoration. It includes all new bearings, snap rings, bushings, and seals. Best of all, the TRK-400 kit features a crucial engineering upgrade: it updates the legacy idler gear and shaft to the newer version utilizing modern needle bearings. This significantly reduces friction, lowers operating temperatures, and extends the lifespan of your rebuilt gearbox. **[TRK-400 Argo Transmission Rebuild Kit, Gen 1 (1990-2007)](https://parts.docsfullboreoutdoor.com/products/trk-400-transmission-rebuild-kit-gen-1-bigfoot-conquest-response-vanguard "TRK-400 - ARGO TRANSMISSION REBUILD KIT, GEN 1 (1990-2007)")** ![TRK-400 - ARGO TRANSMISSION REBUILD KIT, GEN 1 (1990-2007) - 1](https://cdn.shopify.com/s/files/1/0955/3153/2597/files/TRK-400-3.png?v=1783540185) ## Argo Classic & Admiral Transmission Support Doc's support doesn't end with the Generation 1 transmission. If you run a newer era of Argo, they have you covered with targeted rebuild kits: **[TRK-401: Complete transmission rebuild kit for the Argo Classic transmission.](https://parts.docsfullboreoutdoor.com/products/trk-401-transmission-rebuild-kit-classic-gen-ii-2004 "TRK-401 - ARGO TRANSMISSION REBUILD KIT, CLASSIC/GEN II (2004+)")** **[TRK-402: Complete transmission rebuild kit for the Argo Admiral transmission.](https://parts.docsfullboreoutdoor.com/products/trk-402 "TRK-402 - ARGO TRANSMISSION REBUILD KIT, ADMIRAL (2010+)")** * * * ## Stopping Power: The 610-80-AM Splined Brake Rotor One of the most frustrating pain points for owners of 1999 to 2007 Argo Bigfoot, Conquest, and Response models has been the braking system. The original 610-80 splined brake rotor with the idler chain sprocket attached is a notorious wear item if you don't keep your chain adjusted, and once Argo discontinued it, many machines were left completely stranded without a replacement. Recognizing how critical this part is to keeping customers units going, Doc’s designed the 610-80-AM aftermarket splined brake rotor. Proudly made in the USA, this heavy-duty replacement offers smooth, predictable braking performance and perfect spline engagement. It is the ultimate lifeline for 1999-2007 models. **[](https://parts.docsfullboreoutdoor.com/products/610-80-am "610-80-AM - DISC, BRAKE - SPLINED #50-2X13T")** **[610-80-AM - Disc, Brake Splined #50-2x13 Tooth](https://parts.docsfullboreoutdoor.com/products/610-80-am "610-80-AM - DISC, BRAKE - SPLINED #50-2X13T")** ![610-80-AM - DISC, BRAKE - SPLINED #50-2X13T - AFTERMARKET - ARGO PARTS - 1](https://cdn.shopify.com/s/files/1/0955/3153/2597/files/610-80-AM-1.jpg?v=1782740116) * * * ## Don’t Retire Your Argo—Rebuild It An older Argo is far too valuable to abandon over a lack of factory support. Thanks to Doc’s Full Bore Outdoors commitment to American manufacturing and powersports preservation, you can overhaul your drivetrain with confidence.
