The Inland Empire Driveline High-Strength Driveshaft CF6769-350 is a custom-built replacement for 1967–1972 Chevy/GMC C10/K10 trucks with a TH350 or 700R4 automatic and 12-bolt or 10-bolt rear axle. If your original two-piece shaft has worn carrier bearing issues, this one-piece eliminates the center bearing completely.

Constructed from 3.5-inch diameter 0.083-inch wall 1026 DOM steel tubing, dynamically balanced to within 0.5 oz-in at 4,000 RPM. Welded with full-penetration TIG at yoke and tube joints, featuring 1310-series u-joints matching typical GM applications. Yoke ends are heat-treated 4140 chromoly with precisely broached splines. Maximum operating angle rating is 6 degrees. Made to length based on your measurements.

Converting to a one-piece driveshaft eliminates the carrier bearing failure point that plagues C10s and removes the two-piece configuration's inherent harmonic issues. The 3.5-inch DOM tubing handles substantial torque—sufficient for 400+ HP small-blocks and moderate big-blocks. Inland Empire builds each shaft to your exact spec.

Replace that rattling two-piece shaft with a smooth, balanced one-piece from Inland Empire. Order your custom CF6769-350 today.

Frequently Asked Questions

What material and wall thickness does the Inland Empire Driveline driveshaft use?

Inland Empire Driveline high-strength driveshafts are constructed from 6061-T6 or 6063-T6 aluminum alloy tubing with a wall thickness of 0.083 to 0.125 inches, depending on the length and torque requirements of the application. The aluminum construction reduces rotating mass by 40 to 60 percent compared to a steel driveshaft, allowing the drivetrain to accelerate more quickly. Each driveshaft is precision-balanced at speeds over 4,000 RPM to eliminate vibration at highway speeds.

How much horsepower and torque can the Inland Empire aluminum driveshaft handle?

Inland Empire Driveline aluminum driveshafts are rated to handle up to 600 to 800 horsepower and similar torque levels in most street and strip applications, depending on the tube diameter and wall thickness selected for the build. For applications exceeding 800 horsepower or using nitrous oxide, Inland Empire recommends their heavy-wall aluminum or chromoly steel driveshafts for additional torsional strength. The slip yoke is made from heat-treated 4340 steel to withstand high torque loads without twisting.

Do I need to measure my existing driveshaft length before ordering an Inland Empire replacement?

Yes, you must measure the center-to-center distance between the transmission output shaft seal and the differential pinion flange face with the suspension at ride height to determine the correct driveshaft length for a custom-order Inland Empire unit. The slip yoke must have enough engagement on the transmission output shaft while allowing for suspension movement. Inland Empire provides detailed measuring instructions and a specification sheet to ensure your custom driveshaft is built to the correct length.

What u-joints and yoke sizes are compatible with Inland Empire Driveline driveshafts?

Inland Empire Driveline driveshafts are built with your choice of u-joint sizes including 1310, 1330, 1350, and 1410 series, with the yoke style matching your transmission output shaft and differential pinion flange. The 1350-series u-joint is the most common for performance applications handling up to 600 horsepower, while 1410 joints are used for higher-torque applications. The slip yoke is machined to match your transmission's spline count, typically 27 or 31 splines for GM applications.

Will an Inland Empire aluminum driveshaft reduce vibration in my lowered truck?

An Inland Empire aluminum driveshaft can help reduce driveline vibration in lowered trucks because it is precision-balanced and the aluminum construction is more forgiving of minor angularity changes than steel. However, if your truck has driveline vibration from incorrect pinion angle after lowering, the driveshaft alone will not fix the issue unless the transmission and pinion angles are corrected first. A one-piece aluminum driveshaft eliminates the carrier bearing of a two-piece design, removing a common source of vibration.

What is the difference between a custom order and an off-the-shelf Inland Empire driveshaft?

A custom-order Inland Empire driveshaft is built to your exact specified length, tube diameter, wall thickness, u-joint size, and yoke configuration, making it ideal for modified vehicles with engine swaps, transmission changes, or unique axle configurations. Off-the-shelf driveshafts fit common stock applications with standard transmission and axle combinations. Custom shafts come with a blueprint of your specific driveline measurements and are typically balanced to a higher RPM specification of 5,000 to 6,000 RPM.
