Review CHRIS ALSTONS CHASSISWORKS F body Tubular Transmission Crossmember fits NOVA 1967-69–1968-74

Introducing the Chris Alston's Chassisworks K6069 Tubular Transmission Crossmember, a high-performance upgrade for your 1967-69 F-Body or 1968-74 Nova. This crossmember is specifically designed for use with TH400 transmissions.

This crossmember is meticulously crafted from heavy-duty 4130 chromoly steel tubing. The tubular design not only provides exceptional strength and rigidity but also reduces unsprung weight for improved handling and ride quality. The crossmember has been engineered to bolt directly to the factory mounting points on the transmission and chassis, ensuring a seamless installation process.

One of the key features of this crossmember is its adjustable engine mounting points. These adjustable mounts allow for fine-tuning of the engine position, ensuring proper alignment with the transmission and differential. This not only results in improved power transfer but also helps to eliminate common issues such as vibration and noise.

Another benefit of the K6069 crossmember is its integrated transmission mount. This mount is designed to provide optimal support and positioning of the TH400 transmission, reducing the likelihood of transmission damage during hard acceleration or aggressive driving.

The crossmember also includes built-in provisions for mounting an accessory torque converter cooler. This cooler helps to maintain optimal operating temperatures for the transmission, extending its lifespan and improving overall performance.

In addition to its robust design and performance benefits, the K6069 crossmember also boasts a polished finish. This not only looks great under the hood but also helps to protect the crossmember from corrosion and other environmental factors.

Overall, the Chris Alston's Chassisworks K6069 Tubular Transmission Crossmember is an essential upgrade for any enthusiast looking to maximize the performance and reliability of their TH400-equipped 1967-69 F-Body or 1968-74 Nova. With its uncompromising strength, adjustable engine mounts, integrated transmission mount, and built-in cooler provisions, this crossmember is sure to deliver results that are both functional and aesthetically pleasing.
