Key factors that affect air ride suspension fit

o Fitment of Motor

o Tire Height

o Tire Width

o Wheel Offset & Backspace

o Spindle Model Year & Type

o Fenders & Firewall

GSI’s kits are designed to accommodate a common set-up; slight variances can occur with fenders and the firewall.

We recommend purchasing your air ride suspension first, and then purchasing wheels & a motor that will fit your suspension. Suspension is designed to accommodate motor & wheel sizes; it is not a one type fits all sizes. GSI suspension kits and frames are designed for SB/LS based engines, other engines will require extra modifications.

GSI Designed the '63-72 Front Suspension Kit off a '71-72 Spindle.

The '63-72 Front Suspension Kit REQUIRES THE USE OF A '71-72 Disc Brake Spindle

('71-72 Drop Spindle Style is another option)

Save yourself time & money and purchase components that fit your suspension.

Be sure to have your suspension installed by a certified installer that is familiar with air ride suspension.

Always test fit everything before paint or powder-coat.
