How to Measure Shocks

KYB Shock Dimensions

Measuring Points for Shock Absorbers

Measuring points differ based on the mounting style. Extended and Compressed lengths are measured:

  1. From center of eyering to center of eyering
  2. From center of eyering to shoulder of stud
  3. From shoulder of stud to shoulder of stud



KYB Shock Mount Identification

ID = Inside diameter
OD = Outside diameter
E1 = Eyering with 5/8" ID rubber bushing
E1 - L/E = Large eyering with rubber bushing
The (xxx) after L/E is the bushing ID.
E2 = Eyering with bushing and metal sleeve
The (xxx) after E2 are the sleeve dimensions.
Example: (12 x 32) = 12mm ID x 32mm wide
E3 = Eyering with slotted barpin
The (xxx) after E3 is the barpin slot dimensions & rotation.
Example: (48 x 80 x 0) = 48mm from slot ID to slot ID,
80mm barpin OD, with 0 degrees rotation. (means barpin is
perpendicular to shock body)
S1 = Standard 3/8" / 10mm OD stem (bayonet) mount
S1(xxx) = Stem with special dimension
Example: S1(12mm) = 12mm OD stem
S-BRKT = Special bracket with studs
Special = Special mount configuration
