If your pickup’s leaf spring hardware is stretched, corroded, or otherwise compromised, replacing the bolts and associated fasteners restores secure axle alignment and suspension clamping. This kit supplies hardened steel components engineered to match original equipment fitment for many C/K and Silverado/Sierra platforms, allowing a straightforward, reliable swap during a suspension service or axle rebuild.

Will this bolt kit fit my 1988–2002 Chevy or GMC truck?

This Opuiue kit covers a broad range of models from that era, including C1500/K1500, C2500/K2500, C3500/K3500, Silverado, Sierra, Suburban, Tahoe, and Yukon variants. Always confirm year, model, cab/bed configuration and trim against your vehicle’s existing bolt size before ordering to ensure a direct match.

• Fits many 1988–2002 Chevrolet and GMC full-size trucks and SUVs.
• Direct-replacement hardware sized 9/16" x 4-1/2".
• Check OEM part numbers or measure current bolt for final verification.

How durable are these bolts for heavy-duty suspension use?

Each bolt, lock nut and washer in the kit is manufactured from Grade 8 hardened steel to provide higher tensile strength and better wear resistance than standard fasteners. The increased hardness reduces stretching and thread failure under heavy loads and repeated service cycles, improving long-term clamping performance.

• Grade 8 hardened steel for superior tensile strength.
• Hardened lock nuts and flat washers to resist deformation.
• Corrosion-resistant finish designed for road and off-road exposure.

What’s included and how does this simplify installation?

The kit bundles all the necessary hardware to replace multiple leaf spring mounts at once—six bolts, six lock nuts and twelve flat washers—so you can complete a full-side or full-axle service without sourcing extra parts. Packaging the matched components removes guesswork and helps ensure consistent torque and clamping across mounts.

• 6 x 9/16" x 4-1/2" Grade 8 bolts.
• 6 x hardened lock nuts for secure fastening.
• 12 x hardened flat washers to distribute load and prevent embedment.

Will using this kit affect alignment or ride quality?

Replacing degraded leaf spring bolts with properly sized Grade 8 hardware helps re-establish the intended spring clamp and axle positioning. While hardware alone won’t correct worn springs or bushings, fresh bolts and washers reduce movement at mounting points and can restore stability and consistent handling that was lost due to loose or corroded fasteners.

• Restores proper clamping to reduce play at spring eyes.
• Helps maintain axle alignment when combined with other suspension maintenance.
• Recommended when springs, shackles, or bushings are replaced or serviced.

Who this is for: This Opuiue Leaf Spring Bolt Kit is intended for mechanics, restoration shops and DIY truck owners working on 1988–2002 Chevrolet and GMC full-size trucks and SUVs who need a direct-fit, high-strength replacement for worn or corroded leaf spring mounting hardware. Choose this kit if you want matched Grade 8 components to complete a suspension service, axle reinstall, or to ensure dependable fastening for towing and heavy-duty use.
