Prothane 6-1147 Rear Sway Bar & End Link Bushing Kit 25mm

The Prothane 6-1147 is a rear sway bar and end link bushing kit designed as a direct-fit polyurethane upgrade for the factory rubber stabilizer bar bushings. Precision-fabricated to fit a 25mm rear sway bar, this kit delivers measurably improved handling response and body roll reduction compared to soft OEM rubber components.

Factory rubber sway bar bushings are prone to warping, cracking, and losing their grip on the bar over time — allowing the stabilizer bar to shift and reducing its effectiveness. Prothane's polyurethane formulation resists road grime, oils, weather, and road salts that cause rubber to deteriorate, maintaining a secure, consistent grip on the bar throughout the life of the vehicle.

Key Features:

• 25mm bore diameter — precision fit for OEM rear stabilizer bar
• Grooved bore design — engineered to retain Prothane Super Grease for quiet, squeak-free operation
• Premium polyurethane construction — resists oils, road grime, and weathering that degrades rubber
• Includes end link bushings — complete rear sway bar bushing kit in one package
• Available in red or black — both colors share the same durometer (hardness) and performance characteristics
• Direct-fit replacement — no modifications required for proper installation
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the original purchaser's vehicle

Upgrading to Prothane polyurethane bushings delivers a handling improvement comparable to installing a larger diameter sway bar, at a fraction of the cost. Prothane Super Grease should be applied during installation to ensure smooth, quiet operation. Made in the USA.
