4 U-Bolts/12X234X6 Round

The 4 U-Bolts 12X234X6 Round by Skyjacker is engineered for serious suspension work on lifted trucks, off-road vehicles, and heavy-duty applications where axle control and load retention are non-negotiable. U-bolts are critical fastening components that clamp leaf springs to axle perches, preventing axle wrap and maintaining consistent suspension geometry under acceleration, braking, and cornering forces. Whether you're running a lifted 4x4, a utility rig, or a vehicle with aftermarket suspension, quality u-bolts are essential for safe, predictable handling and component longevity.

These round u-bolts feature a 1/2-inch (12mm) diameter shaft with a 2.34-inch leg spacing and 6-inch overall height, designed to accommodate standard axle perch configurations on light to mid-duty suspensions. The rounded design distributes clamping force more evenly across curved spring eyes than flat-stock alternatives, reducing stress concentration and preventing spring eye damage. Skyjacker's hardware is manufactured to exacting tolerances and finished with corrosion-resistant plating to withstand road salt, mud, and constant vibration without seizing or degrading—critical for vehicles operating in harsh environments or high-mileage service.

This four-pack is ideal for mechanics, lift kit installers, and DIY enthusiasts replacing worn suspension hardware during spring replacement, lift installation, or routine suspension overhaul. Proper torque specification and u-bolt orientation are essential during installation—always consult your vehicle's service manual or lift kit documentation to ensure correct preload and prevent axle misalignment. Skyjacker u-bolts are commonly used in restoration work and heavy-duty rebuilds where reliability trumps cost, making them a trusted choice for professional shops and serious off-road builders.
