Rear Axle Leaf Spring U-Bolts with Plates for 1988-1999 C/K 1500 - Fit

In this review of the Rear Axle Leaf Spring U-Bolts with Plates, the bottom line is simple: these U-bolts are aimed at owners restoring or maintaining late 1980s to 2000 GM full-size trucks and SUVs who need correct-fit replacement hardware at a modest cost. The kit replaces the rear, left and right U-bolts for 2.5' wide leaf springs and offers straightforward installation with zinc-coated parts and plates included. It is best for a routine suspension rebuild where correct dimensions and included hardware matter most.

Key Features

• Complete hardware kit: The package includes 4 square zinc-coated U-bolts, nuts and washers plus 2 U-bolt plates so installers do not need to source additional pieces.
• Exact fit dimensions: The U-bolts measure 8.75' from the bottom of the bend to the threads, 2.5' wide with 9/16' diameter, matching the original mounting geometry for C/K 1500 leaf springs.
• Wide model coverage: Fitment lists a range of GM trucks and SUVs, including C1500/K1500, Suburban, Tahoe, Yukon, Blazer and Escalade years, reducing fitment guesswork for many owners.
• Zinc coating: The square zinc-plated finish helps resist surface corrosion during installation and initial service life, easing handling and assembly.
• Durable construction: Made of high-quality metal intended for long-term use, the components feel solid for standard suspension clamping tasks.

Who It's For

This kit is for do-it-yourself mechanics, restoration shops and owners of 1988-1999 Chevrolet and GMC 1500 trucks and the related SUVs who need a direct-replacement U-bolt kit for 2.5' wide leaf springs. It fits rear, left and right placements and is useful when springs are being replaced, axles re-centered or hardware is corroded.

Owners seeking OEM-grade plated hardware with included plates will find this appropriate, but those who require stainless steel, heavy-duty chromed finishes, or enhanced nut anti-seize features should look elsewhere. Also, buyers should verify part numbers 15592585 and 15592586 against their vehicle before ordering.

Pros & Cons

Pros

• Correct dimensions (8.75' length, 2.5' width, 9/16' diameter) that match many GM 1500 leaf spring applications.
• Includes plates and necessary hardware so installation is convenient and complete.
• Zinc coating and solid construction give reasonable surface protection and durability for standard use.
• Broad fitment across Chevy and GMC trucks and SUVs reduces uncertainty for many owners.

Cons

• Some customers report nut retention and threading issues where nuts seize after a few turns, indicating occasional quality control variability.
• The silver plating may concern buyers who prefer stainless or other premium finishes for long-term corrosion resistance.
