RCV Ultimate 30-Spline Front CV Axle Set | 4WD Solid Axle (1984-85 4Runner / 1979-85 Pickup)

RCV Ultimate 30-Spline Front CV Axle Set For 1984–1985 Toyota 4Runner / 1979–1985 Toyota Pickup 4WD with a Toyota solid front axle. Overview The RCV Ultimate 30-Spline Front CV Axle Set is a heavy-duty front axle upgrade for early Toyota 4WD solid-axle applications. The factory Toyota design uses 30 splines at the differential but reduces to 27 splines at the CV joint. RCV replaces that reduced section with a 30-spline CV interface and 300M CV race, eliminating the factory-style neck-down at a common high-load area. Choose the Standard configuration for a stock-width Toyota housing, the +3" Aftermarket Housing configuration for housings that extend the short-side axle by 3 inches, or 300M Inner Shafts for stock-width fitment with upgraded 300M inner shafts.
