Spicer 2-70-18X Driveshaft End Yoke Bearing Strap & Bolt Kit (1310 / 1330 Series)

Secure your driveshaft universal joint, eliminate drivetrain clunking, and prevent high-speed on-road u-joint failures with this genuine Spicer Universal Joint End Yoke Bearing Strap Kit. Engineered as a high-durability original equipment manufacturer (OEM) replacement hardware pack by Dana, this premium kit (Part Number: 2-70-18X) provides the exact tensile clamping reliability required to keep your driveline securely anchored under high-torque acceleration.

On rear-wheel-drive and four-wheel-drive vehicles, the half-round end yoke at the transmission output, transfer case case, or differential pinion acts as the primary interface securing the spinning driveshaft. This strap kit clamps directly over the universal joint bearing caps, seating them rigidly into the alignment slots of the yoke. Over years of hard daily driving, heavy payload tracking, or exposure to moisture and road salt, factory fasteners can experience natural metal stretch, thread fatigue, or severe rust degradation. If your u-joint straps become loose, structural slop is immediately introduced into your driveline, causing a prominent clunking sound when shifting gears and an aggressive chassis shudder at highway speeds. Worse yet, reusing old, stretched hardware increases the risk of a bolt snapping, which can drop a spinning driveshaft at speed. Sourcing a fresh, authentic Spicer hardware kit preserves factory clamping specifications.

Manufactured by Dana Spicer—the industry benchmark in global drivetrain engineering—this kit is forged from premium structural steel and heat-treated to maximize fatigue resistance. Designed to service one half-round end yoke assembly, the kit features a 0.250-28 (1/4"-28 Fine Thread) bolt profile and is precisely sized for a 1.416-inch center-to-center hole width to comfortably cradle 1.062-inch outer diameter bearing caps. It includes specialized bolts with pre-applied locking patches that resist backing off under extreme operating vibrations and temperature fluctuations. Whether you are swapping a pinion seal, upgrading an end yoke, or replacing a worn u-joint, installing brand-new OEM hardware guarantees total peace of mind on and off the road.

Kit Contents:

• (2) Genuine Spicer High-Tensile Steel Bearing Straps

• (4) Precision-Threaded Fine Hex-Head Bolts (with factory thread-locking patches)

Kit Highlights:

• Perfect Clamping Uniformity: Contoured precisely to wrap around the bearing cap, providing consistent structural retention and minimizing the risk of cap distortion.

• Resists Vibrational Loosening: Packed with heavy-duty bolts featuring an integrated thread-locking compound to hold their torque setting under relentless undercarriage resonance.

• Genuine Spicer OEM Forging: Fabricated with exact material densities and thread tolerances specified by original factory equipment blueprints.

• Universal Series Compatibility: Provides a direct drop-in fastening solution across a massive range of classic muscle cars, vintage hot rods, half-ton trucks, and 4x4 Jeep platforms running 1310 or 1330 series driveline configurations.

Drivetrain & Installation Specifications:

• Driveline Series Architecture: 1310 Series (including SPL22) and 1330 Series (including SPL25).

• Target Bearing Cap Diameter: 1.062 inches (1.063" nominal).

• Center-to-Center Bolt Hole Spacing: 1.416 inches.

• Thread Profile Diameter: 0.250-28 UNF (1/4" Fine Thread).

• Crucial Torque Specification: Professional installation requires tightening hex bolts evenly in an alternating pattern to exactly 13–15 lb-ft (18–20 N·m). Do not over-torque, as crushing the bearing cap will trap the internal needle rollers and cause rapid u-joint failure.
