Generic Chevy/GMC C10 C20 Truck Rubber Bed Mounting Kit — 1947–1987 8-Piece, OEM-Style Durable Rubber

An 8-piece rubber bed mounting kit engineered to replace worn mounts on 1947–1987 Chevy and GMC C10/C20 trucks, restoring a secure, vibration-dampened connection between bed and frame.

When rebuilding or maintaining a classic C10 or C20 pickup, the bed mounts are small parts that make a big difference. Over decades the original rubber mounts dry out, crack or compress, allowing noise, poor alignment and uneven load transfer. This complete 8-piece replacement set is molded from durable rubber and sized to match original equipment for a straightforward swap that brings back proper fit and quieter operation.

How do these mounts improve ride quality and reduce rattles?

Worn bed mounts let metal contact metal and transmit road shock into the cab and bed, producing clunks and continuous vibration. Rubber mounts restore the isolating layer between bed and frame, absorbing impacts and reducing noise. They also maintain the correct spacing for the bed so panels don’t rub against the frame.

• Vibration absorption reduces audible rattles and harshness.
• Correct spacing prevents sheet metal contact and wear.
• Durable rubber resists compression set for longer life.

Will this kit fit my 1947–1987 Chevy or GMC C10/C20 without modification?

This 8-piece kit is designed to match the original mount sizes used across many C10 and C20 model years between 1947 and 1987, making it a direct replacement in most restorations. Minor variations in aftermarket beds or heavily modified frames may require a quick test fit. For factory-style beds and frames, these mounts install without trimming or alteration.

• Engineered to original dimensions for direct fit on OEM beds and frames.
• Works across a broad range of model years in the 1947–1987 span.
• Test-fit recommended on heavily modified or custom chassis.

How simple is the installation process for a home restorer?

Replacing bed mounts is a straightforward job for anyone with basic hand tools and a safe method to support the bed while mounting. Because the kit contains all eight rubber pieces, you can swap one at a time while supporting the bed, or remove the bed for a full replacement. No special adhesives or complex machining are required.

• Install one mount at a time while supporting the bed for safety.
• Fits into existing mounting hardware—no adhesive needed.
• Can be done with common hand tools and basic mechanical know-how.

What are the material benefits and longevity I can expect?

These mounts are molded from resilient rubber formulated to resist cracking, oil contamination and compression set. While rubber will age over many years, this kit offers improved durability compared with brittle, factory-age parts and restores the designed load-distribution characteristics of the bed-to-frame connection. Regular inspection during routine maintenance will extend service life.

• High-quality rubber resists tears and weathering for extended use.
• Maintains load distribution to protect bed and frame integrity.
• Simple to inspect and replace as part of routine restoration upkeep.

Who this is for: This 8-piece rubber bed mounting kit is ideal for classic truck owners, restorers and mechanics working on Chevy and GMC C10/C20 models from 1947 through 1987 who want a correct-fit, durable replacement for worn mounts. It suits vehicles returning to factory specification as well as daily drivers seeking quieter operation and improved bed stability.
