BST BSSP U-Bolt Kit 4PCS for 2.5" Leaf Springs — 8.75" Zinc-Coated U-Bolts with Hardware, fits 1988–2019 Silverado/Sierra

BST BSSP 4PCS square U-bolts are zinc-coated fasteners sized for 2.5" wide leaf springs, 8.75" long, sold with complete mounting hardware for compatible 1988–2019 Chevrolet Silverado and GMC Sierra 1500 trucks.

The 8.75" measured length and 9/16" diameter are specified for rear lift block/deaver applications; always verify fitment with your vehicle year, make, model and trim before ordering.

How are these U-bolts protected from corrosion and road wear?

• Zinc coated finish for improved rust resistance.
• Solid steel core for strength under load and repeated use.
• Supplied with matching nuts and washers to ensure a sealed clamping assembly.
• Periodic inspection recommended for vehicles driven on salted roads or off-road.
