NOTE:
All springs except those marked by an asterisk (*) are 76 mm (3”) wide.
Hook location shows leaf number on which hook is located (L - Front End, R - Rear End).
Model 21 uses both hooks in the equalizer.
Models 21B, 101A, 102 - Hooks to the Rear, 101 - Hooks to the Front.
Models 101F, 181 - Front spring hooks to the Front, Rear spring hooks to the Rear.
REYCO™ springs are symetrical
IMPORTANT:
If using Hutchens™ style springs, specific hook placement is required.
Not all Hutchens™ style springs will fit correctly when used in Reyco™ suspensions.
Call factory if using Hutchens™ style springs for correct spring hook alignment.
Hutchens™ springs are asymetrical
