Hi-Per Blue High-Performance Bonded Pistons

About

Upgrade your transmission’s reliability with Hi-Per Blue Bonded Pistons , the professional choice for high-performance and heavy-duty rebuilding. Standard OE pistons often utilize Alkyl Acrylate Copolymer (ACM), which can harden and fail under extreme heat or aggressive fluid additives. Hi-Per Blue pistons are reengineered with upgraded AEM (Ethylene Acrylic Elastomer) , a best-in-class material that maintains its flexibility and sealing integrity far longer than factory components. Why Professionals Choose Hi-Per Blue: Superior Thermal Resistance: Rated for extreme temperature ranges, preventing the "hardening" that leads to internal pressure loss and burnt clutches. Advanced AEM Material: Offers higher tear strength and better compressive stress relaxation compared to standard ACM rubber. Enhanced Bonding: Reengineered bonding characteristics ensure the seal remains attached to the piston even under high-cycle dynamic fatigue. Chemical Durability: Exceptional resistance to acid condensates and aggressive transmission fluid additives. Vibration Dampening: The unique blue AEM material provides superior dampening, leading to smoother shifts and reduced mechanical wear.
