SuperPro SPF2575K Lower Rear Engine Steady Mount Bush Insert Kit

The SuperPro SPF2575K is a polyurethane lower rear engine steady mount bush insert kit designed as a direct replacement for the original rubber bushing. This void-filling insert installs into the voiding of the existing factory mount bushing, reducing excess engine movement and restoring proper drivetrain stability without requiring full mount replacement.

Key Features:

• Void-filling insert design — installs directly into the original bushing void, reducing engine movement and improving grip
• Smoother gear selection — minimizes drivetrain slop for more precise, confident shifting
• Proprietary engineering-grade polyurethane — combines the compliance of rubber with the durability of rigid plastic for a long-lasting, balanced result
• Quicker throttle response — reduces engine shift under acceleration for improved power transfer
• Resistant to oils, water, coolant, and extreme temperatures — outperforms standard rubber in harsh operating conditions
• OEM cross-reference: 1J0199851AB
• Backed by SuperPro's Lifetime Warranty — covers all use including off-road, track, and competition

SuperPro's engine steady bush insert offers a cost-effective performance upgrade over worn or soft factory rubber mounts. The polyurethane compound is firmer than stock rubber, delivering improved engine stability and throttle feel while remaining far less harsh than solid metal racing mounts — making it a practical choice for street-driven and performance-oriented vehicles alike. Developed and engineered in Australia by a dedicated R&D team with 40+ years of automotive experience.
