TSP Radiator Shroud Rubber Flap

• Flexible rubber flap reduces air recirculation through unused fan shroud openings

• Simple push-in or trim-to-fit installation for custom shroud configurations

• Universal fit for shroud openings and fan clearance gaps sized to accept this flap

• Durable rubber construction withstands engine bay heat and vibration

This TSP radiator shroud rubber flap is a flexible seal designed to close off unused openings or excess clearance gaps in a fan shroud, helping reduce air recirculation and improve fan pull-through efficiency. Rubber construction flexes around the fan blade path without interfering with fan operation, while resisting engine bay heat and vibration over time.

This is a universal-fit flap, not a shroud or radiator — fitment depends on matching the flap to your shroud opening or clearance gap, not on vehicle make or model. Compare the flap's dimensions to your specific shroud cutout before ordering, since shroud openings vary significantly across custom and aftermarket shroud designs.

When to Use This Flap
Fan shrouds with oversized cutouts, custom-fabricated shrouds, or shrouds paired with a smaller fan than the opening was designed for can allow air to recirculate around the fan instead of pulling through the radiator core. This flap closes that gap, helping direct more airflow through the radiator itself.

Installation
Compare the flap's dimensions against your shroud's opening or clearance gap before ordering — this flap is sized to fit specific gap dimensions and isn't a universal one-size-fits-all shroud panel. Trim or position as needed so the flap doesn't contact the fan blade during operation.

What does this flap actually do?
This flap helps seal unused openings or clearance gaps in a fan shroud, reducing air recirculation so the fan pulls more air through the radiator core.

Will this fit my shroud opening?
Fitment depends on the dimensions of your shroud opening or gap. Measure the area you need to cover and compare it with the flap dimensions before ordering, especially with custom or aftermarket shrouds.

Can this flap contact the fan blade?
No — the flap must be positioned so it stays clear of the fan blade path at all times. It's designed to seal an opening, not contact the rotating fan.

Is this a full shroud replacement?
No — this is an individual sealing flap, not a complete fan shroud or radiator component. It's intended for use with an existing shroud.

How many do I need?
This flap is sold individually. Order the quantity needed to cover the openings or gaps in your specific shroud setup.

What material is this flap made from?
It's made from black rubber, providing the flexibility needed for use as a fan-shroud sealing flap.
