MUFFINMAN Automotive Rubber Bumper Assortment — 160‑Piece, 12 Sizes, Black, Weather‑Resistant

MUFFINMAN Automotive Rubber Bumper Assortment is a 160-piece kit of black rubber bumper stoppers in 12 commonly used sizes, designed to fit and protect glove boxes, trunks, hoods, doors, and other vehicle panels.

This assortment gathers the most frequently needed rubber bumpers into one clear, compartmented storage box so you can replace worn or missing stoppers quickly. Each bumper is molded from a resilient rubber compound engineered to resist corrosion and maintain flexibility in hot, cold, and humid conditions. The set covers a wide range of automotive applications and includes parts sized for license plates, trunk lids, door headers, quarter glass, glove boxes and general-purpose cushioning.

Which vehicle areas can these rubber bumpers protect?

These bumpers are intended for non-structural contact points where panels meet or close, reducing vibration, noise, and wear between surfaces. They work well on glove boxes, trunk and hood lids, license plate mounts, door edges, quarter glass seals, and interior trim points.

• Glove box door cushioning — includes a small-diameter stopper for precise alignment.
• Trunk, rear deck lid & hood — larger-diameter bumpers for wider contact areas.
• License plate and exterior mounts — medium-sized stoppers that fit common holes.
• Door opening headers and quarter glass — stem lengths suited to recessed mounts.

How do I choose the right size from the 12-size assortment?

Select a bumper based on the hole diameter, stem length, and head diameter that match your original part or the mounting hole. The kit is labeled by part group and dimensions, letting you compare measurements quickly; if unsure, measure the existing stopper or hole before installation.

• Hole size ranges from about 3.6 mm to 27/64" for common mount fittings.
• Stem lengths vary up to 22.22 mm for recessed or thicker panels.
• Head diameters range from small contact points to larger 22.22 mm pads for broad support.
• Clear storage tray keeps sizes separated and identifiable at a glance.

Are these bumpers durable and weather-resistant?

The rubbers are formulated to maintain flexibility and resist environmental breakdown, performing reliably in high temperature, cold climates, and humid conditions. Their corrosion-resistance and elasticity help maintain cushioning and alignment over time, making them suitable for both interior and exterior applications.

• Weather-resistant rubber compound for long-lived compression recovery.
• Resists cracking and hardening from temperature extremes.
• Suitable for repeated panel contact without premature wear.
• Black finish blends with most factory trim and hardware.

What comes in the kit and how is it organized?

The set includes 160 pieces across 12 different sizes tailored to fit most car models, arranged in a handy storage box for fast selection. Each compartment is marked for its contents so you can quickly identify the size you need during repairs or restorations.

• Total: 160 rubber bumpers in 12 popular automotive sizes.
• Compartments labeled by part grouping and key dimensions.
• Common sizes include small license plate bumpers to large trunk/hood pads.
• Compact box fits in a tool chest, glove compartment, or trunk organizer.

Who is this for: The MUFFINMAN Automotive Rubber Bumper Assortment is aimed at DIY mechanics, car restorers, fleet maintenance crews, and automotive trim installers who need a ready supply of correct-fit rubber stoppers.
