Product details
A pair of stainless-braided rear brake hoses for the specified Porsche 911 2.7/2.7S/3.0 original brake arrangement. Wilwood’s OEM Performance Flexline assemblies use integral application-specific ends and an outer protective coating.
For matching factory-style brake connections. These are Wilwood aftermarket hoses, not genuine Porsche parts. They are a different selection from the hose kits supplied with Wilwood caliper conversions.
Confirm fitment before ordering. The listed engine groups are qualifiers within this broad range. Do not infer every 1973–1989 911 or continuous engine coverage from that heading.

Check the original hoses
Compare the rear hose fittings, seating surfaces, brackets and routing with the parts on your car. Modified calipers, swapped struts or hard lines can change the hose requirement. Confirm the hose dimensions and end fittings against the original parts before ordering.
Installation and help
After installation, each hose must clear the wheel and suspension without rubbing, twisting or becoming tight through steering and suspension movement. Have the complete hydraulic system installed and tested by a qualified brake technician.
Unsure which factory-connection hose your Porsche needs? Contact PMB Performance with the model year, installed brake parts and clear photos so we can help check the match before you order.
