Prothane 7-1171-BL Rear Sway Bar Bushing Kit 1.10in Black Polyurethane

The Prothane 7-1171-BL is a rear stabilizer bar bushing kit designed as a direct, performance-upgrade replacement for worn OEM rubber sway bar bushings. Engineered from premium-grade polyurethane, these bushings provide significantly greater rigidity and durability than factory rubber units, helping to reduce body roll and improve overall handling response.

Designed to fit a 1.10-inch (27.94 mm) rear sway bar diameter, this kit includes both sway bar bushings and end link bushings. The bushings feature a grooved bore design that retains Prothane Super Grease for smooth, quiet operation over the life of the part. The black polyurethane formulation incorporates a small amount of graphite to further aid in noise reduction when properly lubricated at installation.

Key Features:

• Premium polyurethane construction — more durable and firmer than OEM rubber
• 1.10-inch (27.94 mm) bore diameter for precise sway bar fitment
• Grooved bore retains Prothane Super Grease for quiet, long-lasting operation
• Black color with graphite additive for enhanced noise resistance
• Includes rear sway bar bushings and end link bushings
• Precision-fabricated for a correct, no-modify fit
• Backed by Prothane's lifetime warranty to original purchaser

Prothane polyurethane bushings are a proven upgrade for trucks and SUVs experiencing vague steering feel or excessive body lean from fatigued rubber suspension components. Proper greasing at installation is recommended for optimal performance and to prevent squeaking.
