iiLentes Rear Leaf Spring U-Bolt Plate & U-Bolts — 2.5" Wide, 8.75" Spacing, OE Fit

iiLentes rear leaf spring U-bolt plate and matching U-bolts (part numbers 15592585 / 15592586) are replacement hardware designed to secure 2.5" wide, 8.75" long leaf springs on compatible Chevy, GMC and Cadillac trucks and SUVs.

This kit provides the metal plate and bolts needed to clamp the leaf pack to the axle U-bolt on late‑80s through 2000 GM pickup and SUV models. It replaces worn or rusted original equipment, restoring a solid connection between axle and spring for normal driving, towing and hauling. The components are manufactured to OE-style dimensions so fitment aligns with factory spring widths and hanger spacing on the listed vehicles.

Which vehicles will these iiLentes parts fit?

These replacement plates and U-bolts are specified for a range of GM trucks and SUVs from the late 1980s through 2000. Confirm year, model and original spring width before ordering to ensure correct match.

• Chevrolet C1500 and K1500 (1988–1999)
• Chevrolet Suburban and Blazer (1992–1999, 1992–1994 respectively)
• Chevrolet Tahoe (1995–2000) and GMC Yukon (1992–2000)
• GMC C1500/K1500 and Suburban (1988–1999 and 1992–1999 ranges)
• Cadillac Escalade (1999–2000)

How do these plates and U-bolts restore rear suspension function?

When the factory U-bolts or plates rust, stretch or crack, the leaf pack can shift, causing noise, misalignment or unsafe handling. Replacing the hardware clamps the spring to the axle firmly and maintains original ride geometry without requiring new springs.

• Clamps 2.5" wide leaf springs with an 8.75" bolt spacing for accurate alignment
• Replaces OE part numbers 15592585 and 15592586 for left and right sides
• Restores secure axle-to-spring connection for towing and daily driving

What are the installation considerations and torque guidance?

Installation requires lifting the axle enough to relieve spring clamp tension, removing the old U-bolts and plates, then fitting the new hardware. Tighten nuts evenly and to the vehicle manufacturer’s torque specs for U-bolts; re‑check after a short break-in drive.

• Support axle and vehicle safely before starting work
• Tighten nuts evenly in alternating pattern to recommended torque
• Inspect spring pads and axle tube seating for corrosion or damage

What materials and durability should I expect from the iiLentes kit?

The kit is supplied as direct-replacement steel hardware intended to match OEM fitment. It’s produced to withstand typical road use and exposure, though surface finish and long‑term corrosion resistance vary with storage and driving conditions.

• Steel U-bolts and plate sized for 2.5" leaf springs
• Manufactured to match OE dimensions for reliable fitment
• Inspect and replace any heavily corroded components for safety

Who is this for: This iiLentes U-bolt and plate kit is intended for owners and mechanics maintaining late‑80s to 2000 GM trucks and SUVs who need an OE‑style replacement for worn or damaged rear leaf spring hardware. It’s suitable for routine suspension repairs, pre‑sale restorations, or as part of a brake and axle service where leaf‑spring clamp integrity must be restored.
