NOLATHANE Hood Bumper Stops

Nolathane hood bumper stops are built for semi truck tilt hoods, not passenger cars. This range covers the center hood rest that supports the hood when it?s closed, and the hood hinge bushings that let it tilt open smoothly. Together, these hood bumper parts stop rattles, chafing, and hinge play on conventional-cab tractors.

A large fiberglass hood puts constant load on its rest and hinge, and every mile of vibration wears them down. Replacing them restores a quiet, well-supported hood. Each listing shows the original part number cross-reference and the position each part fits.

Semi Truck Hood Rests and Passenger Car Hood Bumpers

When most people search for hood bumpers or hood bump stops, they?re looking for the small adjustable rubber stops on a passenger car. Those screw into the radiator support and set how high the hood sits when it?s closed.

Semi truck hood rests do a different job. A conventional-cab tractor uses a large tilt hood that covers the engine, grille, and front fenders. When it?s closed, that hood rests on supports that carry its weight and keep it steady. This page covers those heavy-duty rests and the hinge bushings that work with them, not passenger car hood bumpers.

How the Center Hood Rest Supports the Hood

The center hood rest sits at the main contact point between the closed hood and the cab structure, often near the cowl. It carries part of the hood?s weight and holds it off the cab, so the two surfaces never rub directly against each other.

It also absorbs vibration. A semi truck hood is heavy and spends its working life shaking over highway miles. A good hood rest pad soaks up that movement, preventing rattles and stopping the hood from chafing or cracking where it touches the cab.

How Hood Hinge Bushings Work

A tilt hood pivots forward on hinges at the front of the truck. The hood hinge bushings sit in those pivots, letting the hood open and close smoothly while keeping the hinge firmly located.

When hinge bushings are in good condition, the hood moves cleanly through its arc and sits square when closed. When they wear, play develops in the hinge pivot, and the hood can wobble side to side or shift out of alignment.

Signs of Worn Hood Rests and Hinge Bushings

Hood support wear usually shows up as noise or a hood that doesn?t sit right. Watch for:

• Hood rattle at idle or on rough roads
• The hood sitting low or uneven at the center
• Chafe marks or cracking at the rest point
• Side-to-side hood movement at the hinge
• A stiff or noisy hinge when tilting the hood
• Flattened, split, or missing pads

Rubber and Polyurethane Hood Bumpers

Rubber hood bumpers and rubber hood stops are common original equipment, but they struggle in this position. Heat from the engine, constant vibration, and the weight of the hood cause rubber to compress, harden, and eventually split.

Polyurethane holds its shape under load far better. It resists abrasion, so it stands up to the constant rubbing at the rest point, and it resists oil, grease, ozone, and weathering. That means a polyurethane hood rest stays supportive for longer, keeping the hood quiet and properly seated.

Checking Hood Support During PM

The hood rest and hinge bushings are easy to check during scheduled preventive maintenance (PM):

• Inspect the center rest pad for flattening, cracks, or missing material
• Check the hinge bushings for wear and the hinge for play
• With the hood closed, push it side to side to feel for movement
• With the hood partly tilted, check that it moves smoothly without binding or wobbling
• Record the condition in the maintenance log so wear can be tracked over time

Catching wear early prevents damage to the hood and cab, which cost far more to repair than the rest and bushings.

Choosing Hood Bumper Stops

Matching the right part is simple with the cross-reference. Each listing shows the details.

Original Part Number Cross-Reference

Match the original part number on your truck to the cross-reference shown in the listing.

Rest Pad or Hinge Bushing

Decide whether you need the center hood rest pad, the hinge bushings, or both.

Replacing Both Sides or the Full Set

Hinge bushings on each side usually wear at a similar rate, so replace both sides together. If the rest pad is worn too, fitting the full set saves a second job.

Fitting Hood Rests and Hinge Bushings

A semi truck hood is heavy, so supporting it safely is essential before any work begins. Qualified fitting by a technician is recommended. The general process looks like this:

• Support the hood securely so it can?t fall or shift
• Remove the worn rest pad or hinge bushings
• Fit the new rest pad or bushings
• Tighten the hinge hardware to specification
• Check that the hood is aligned and the latch engages properly
• Check again after the first few trips

Limitations and Trade-Offs

Hood rests and hinge bushings solve support and play problems, but they have limits:

• They can?t fix a cracked hood, damaged hinge brackets, a worn latch, or cab mount problems
• Polyurethane is firmer than rubber
• They aren?t adjustable passenger car hood bumpers
• Fitment is limited to the listed cross-references

Commercial Vehicle Inspections and Insurance

Make sure the truck meets the federal and state commercial vehicle inspection requirements that apply where it operates. Let your insurance company know about any modifications.

Warranty and Support

Nolathane hood rest pads and hinge bushings carry a lifetime warranty against manufacturing defects in material and workmanship. If you?re not sure which part matches your truck, our local support team can help you check the cross-reference.
