Building a Better C10
Swapping Your Classic Chevy the Right Way
Whether you're building a badass street truck, a reliable cruiser, or dropping the hammer with an LS or Big Block swap, the classic C10 Chevy trucks have become the go-to canvas for gearheads and weekend wrenchers alike. But making that old-school hauler ride and drive like a modern machine takes more than just horsepower. You need parts that work with your build — not against it. That's where G Force Performance Products comes in.
From frame-hugging C10 transmission Crossmembers to smart tools that make engine installs a breeze, G Force has the goods to make your C10 truck swap smoother, cleaner, and just plain better. Let’s break it down by the years and the gear.
🔧 1967 – 1972 C10 Crossmember — A Game Changer for Your Swap
Got a '67–'72 Chevy or GMC C10? Then you know the stock Crossmember just doesn’t cut it when you’re trying to run a modern powertrain. The G Force RCC-10.2-PRO transmission Crossmember is a bolt-in upgrade that gives you proper drivetrain alignment, better exhaust clearance, and support for multiple transmissions like the 4L60E, 4L80E, and TREMEC TKX. Plus, it's made right here in the USA.
🔧 1988–1998 C1500 Crossmember — OBS Truck Swap Support
Swapping an LS into your OBS Chevy? Don’t forget the Crossmember. The RCC-10.4-PRO from G Force is a bolt-in solution for your 1988–1998 Chevy/GMC C1500, built for modern automatics like the 4L80E. It's a great choice for C10s with dual exhaust systems.
With a powder-coated finish and precision construction, it’s not just functional — it looks good under the truck too.
🔧 1973–1987 C10 Transmission Crossmember — The All-Around Performer
The square body C10 is a hotbed for LS and Big Block engines, but if you’re using that stock Crossmember, you’re leaving performance on the table. G Force’s 1973–1987 C10 Crossmember is designed to improve transmission fitment, the installation of performance dual exhaust, and overall driveline geometry. It’s engineered for T56, 4L80E, 4L60E, and even TH400 swaps — with no cutting or welding required.
Whether driving your build daily or taking it to the drag strip, this Crossmember gives you the clearance and strength you need.
🛠️ Make It Easier with the 4-Point Engine Sling
Whether you're dropping in an LS, Small Block, or Big Block, the right tool makes all the difference. The G Force 4-Point Engine Sling (GF-ESLP) gives you safe, balanced engine installation from any angle. It can be mounted in various locations on the engine assembly providing position flexibility and tilt control— perfect for lining up tricky motor mounts during a swap.
