Prothane 15-1601 Porsche Rear Shift Linkage Coupler Bushing Kit - Red Polyurethane

The Prothane 15-1601 is a rear shift linkage coupler bushing kit designed to restore and improve shifter precision on classic Porsche vehicles. Over time, the factory rubber bushings in the shift coupler wear down and deform under the stress of repeated shifts, resulting in a vague, imprecise feel at the gear lever.

Prothane replaces those soft OE rubber bushings with their specially formulated polyurethane — a material significantly more durable and resilient than rubber. Polyurethane holds its shape under pressure, resists warping, and is immune to degradation from motor fluids, road salts, and other under-car chemicals that attack rubber over time.

Key Features:

• Rear shift linkage coupler bushing kit for classic Porsche models
• Manufactured from high-performance polyurethane — more durable than OE rubber
• Firms up shift linkage for more precise, confidence-inspiring gear changes
• Resistant to oil, grease, road chemicals, and physical wear
• Finished in signature Prothane red
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

Once installed, these bushings eliminate the slop and looseness caused by worn OE rubber, restoring — and even surpassing — factory shift feel. An affordable upgrade for any Porsche owner looking for tighter, more confident gear engagement.
