U660E/U760E B3 Brake Piston fits Toyota Lexus (07-Up)

Stellar Automotive Group U660E/U760E B3 (3rd/5th/Reverse) Brake Piston – Compatible for Toyota & Lexus 2007-Up

Eliminate slipping in 3rd & 5th, delayed reverse, and burnt B3 clutches with this high-quality bonded B3 brake piston from Stellar Automotive Group.

This direct-replacement piston is precision-machined from aluminum with a permanently bonded rubber sealing lip that matches factory specs exactly. The original B3 piston frequently cracks or loses its bond under heat and mileage, causing internal leakage that weakens 3rd/5th gear hold and reverse engagement — leading to rapid clutch failure. Installing this upgraded piston during your U660E/U760E rebuild restores full apply pressure, delivers crisp shifts, and provides solid reverse performance mile after mile.

Fits popular models including:

• Toyota Camry, Highlander, RAV4, Venza, Sienna (2007-Current)
• Lexus ES350, RX350, RX450h (2007-Current)

Symptoms of a failing B3 piston:

• Flare or slip in 3rd and 5th gears
• Delayed or weak reverse engagement
• Harsh shifts when clutches finally grab
• Burnt B3 frictions on teardown

Don’t risk another rebuild on a cracked piston — upgrade to the Stellar Automotive Group bonded B3 piston and drive with confidence.
