Innovative Mounts 29151-85A B-Series Steel Engine Mount Kit 85A Bushings

The Innovative Mounts 29151-85A is a complete replacement engine mount kit engineered for the 1988-1991 Honda Prelude BA chassis equipped with factory B20a or B21 engines and 5-speed manual transmissions. This performance mount kit replaces fluid-filled OEM rubber mounts with precision-engineered black steel mounts featuring 85A durometer polyurethane bushings for enhanced drivetrain response and reduced wheel hop.

Key Features:

• CAD/CAM designed solid steel construction for maximum durability
• 85A durometer polyurethane bushings—firm setup ideal for high-torque applications and aggressive driving
• Unique no-tear bushing design minimizes vibration transmission to chassis
• Eliminates dampening fluid found in OEM mounts to reduce engine movement
• Stress-analyzed engineering ensures proper load distribution
• Lifetime warranty from Innovative Mounts
• Precision fitment manufactured at state-of-the-art North Carolina facility

This complete kit includes driver side mount, transmission mount, and rear engine mount. The 85A bushing option provides a firm, performance-oriented feel that significantly improves throttle response and power transfer while introducing minimal cabin vibration. Replaces Honda OEM part numbers 50820-SF1-010 and 50816-SF1-020. Note: If using a B21 engine, you must use the stock B20a5 driver side post mount engine bracket and chassis bracket for proper fitment.
