MB springs are selected by a point numbering system..

ON the 1997 E420 the "base" number is 85...add 3 points for sunroof, add 1 point for sound system, add 1 point for H/Ll washer system, & 1 point for ASR.

Depending on equipment you have from 89-91 points.

for a car with 89 points the spring is 210-321-14-04 & the thickest spring pad....

for a car with 90 or more points the number is 210-321-15-04 & the thinnest spring pad.

You know your cars equiptment level...so add up the points...I'll bet that you have the correct spring...

have you driven the car at least 10 miles??
