Ridetech 68-72 GM A-Body w/ Pin Spindle & (Stock) 60.25in Flange to Flange Width Momentum Chassis

Pin spindles and stock-width rear -- this Ridetech Momentum Chassis for 1968-1972 GM A-body cars is the choice for builders who want modern handling with traditional spindle style and factory wheel spacing.

The Straightforward Option

Of the four Momentum Chassis configurations available for the A-body, this one keeps things closest to stock dimensions. The 60.25-inch rear housing matches factory width, so your existing wheels and tires bolt right up. AFX pin spindles maintain compatibility with kingpin-style brake setups. You get all the modern geometry benefits without changing your wheel, tire, or brake components.

Everything Included

The chassis frame, upper and lower control arms, front sway bar, AFX pin spindles, steering components, 4-link bars, body bushings, and stock-width rear housing with axles. Your 1968-1972 A-body shell mounts directly to this platform -- Chevelle, GTO, Cutlass, Skylark, and all related models.

4-Link Rear

The 4-link rear suspension replaces leaf springs with a multi-link system that controls the rear axle more precisely. Wheel hop on hard launches is eliminated, and the rear stays planted through corners. This is one of the biggest single improvements you can make to how these cars drive, and it comes standard with every Momentum Chassis.

A New Lease on Life

Classic A-body cars are worth preserving. When the original frame has seen better days, a Momentum Chassis swap gives the car another 50 years of life on a platform that handles better than it did when it was new. The investment in a complete chassis pays dividends every time you turn the wheel.
