YunGlee Rear Shock Bolt Kit for Chevy Silverado & GMC Sierra 1500–3500 — Class 10.9 Hardened Bolts with Anti‑Corrosion Plating

The YunGlee Rear Shock Bolt Kit supplies four hardened flange bolts and four matching nuts engineered to securely fasten the rear shock absorbers on compatible Chevy Silverado and GMC Sierra trucks.

If your truck's rear shock mounting hardware is worn, rusted, or seized, this replacement kit offers a direct-fit solution for a wide range of Silverado and Sierra model years. The kit is built from Class 10.9 hardened steel with an anti-corrosion plating, so it tolerates heavy loads and road exposure better than common lower-grade fasteners. It’s intended to be used with stock suspension geometry and most aftermarket shocks but isn’t suited for vehicles with significant lift-modifications.

Which truck models and years does this bolt kit fit?

This kit covers many Silverado and Sierra model years and trims across 2WD and 4WD configurations. It fits multiple cab and bed layouts and pairs with most OEM and aftermarket rear shocks. Always verify the specific part dimensions against your truck's original hardware before installation.

• Chevy Silverado: 1500 (2003–2020), 2500 (2003–2014), 2500HD (2003–2015), 3500 (2003–2010)
• GMC Sierra: 1500 (2003–2019), 2500 (2003–2014), 3500 (2003–2010)
• Works with stock 2WD/4WD setups and most aftermarket shocks; not for lifted or heavily modified suspensions

How does the material and coating improve durability?

The bolts are manufactured to Class 10.9 strength, delivering higher tensile capacity than typical Grade 8.8 fasteners. This makes them better suited to resist stretching or failure under heavy load, towing, or off-road vibration. In addition, a corrosion resistant plating helps prevent rust and seizing, simplifying future maintenance or replacement.

• Class 10.9 hardened steel for higher tensile strength
• Protective plating resists oxidation, salt, and moisture exposure
• Designed to remain removable—reduces chance of seized hardware

What’s included and what should I check before installation?

The kit contains four flange-head bolts and four flange nuts—enough to replace both left- and right-side rear shock mounting bolts. Before installing, compare thread size and shank diameter with the existing hardware and inspect the shock brackets for wear or distortion. If your truck has a lift kit or modified mounting points, this kit may not fit properly.

• Includes: 4 flange bolts and 4 flange nuts for rear shock mounts
• Verify thread pitch, diameter, and length against original bolts
• Not compatible with heavily modified or lifted suspensions

Will these bolts work with aftermarket shocks and heavy use?

Yes—these bolts are suitable for OEM and many aftermarket shocks when the vehicle retains factory mounting geometry. The higher-strength steel is chosen to handle elevated stresses from towing or rough roads, but extreme suspension modifications can change load paths and require specialized hardware.

• Compatible with most aftermarket shocks that use stock mounting points
• Built for heavy loads and road vibration within factory suspension specs
• Not recommended for custom-fabricated or extensively altered mounts

Who is this for: The YunGlee Rear Shock Bolt Kit is ideal for Silverado and Sierra owners who need a reliable, higher-strength replacement for corroded or damaged rear shock mounting bolts—especially those who tow, carry heavy loads, or drive in salty or wet conditions. If your truck retains stock suspension geometry and you want removable, heavy-duty hardware that resists rust, this kit is a direct, cost-effective option. If your vehicle has lift modifications or custom rear mounts, consult a suspension specialist to confirm fitment before purchase.
