Overview
The Rough Country R/C7640 is a square U-bolt kit made from 9/16 in. square steel and sized at 2.5 x 11.5. It is built as a replacement or custom-fit U-bolt for solid axles.
The kit is sold as universal fit, so no specific vehicle is named. Confirm the 2.5 x 11.5 size against your axle and spring pack before ordering, since the square profile must match your existing hardware.
Key features
- Square steel profile, unlike the round U-bolts in the same range
- Black e-coat that Rough Country says resists corrosion
- Offered as a replacement or custom-fitting option
Square profile considerations
Square U-bolts seat differently from round ones, so the shape of the bolt matters as much as its size. Square stock has flat faces that bear on the plate and spring pad, which can give a firmer seat when the mating parts are square to the tube. Compare the corners, bends and thread length of the old bolts against the new set before installing.
Because the profile must match the saddle or plate, mixing shapes is not a simple swap. Inspect the spring pad and clamp plate for wear, and replace them if they are cracked or deformed. Coat the threads lightly and use the nuts and washers that match the thread size. Recheck the clamp after the first few drives, particularly if the vehicle sees rough trails.
