Santa Cruz Blur Shock Dimensions: Eye-to-Eye Is Only the First Measurement

Santa Cruz Blur shock dimensions require more than one length. Two dampers can share an eye-to-eye measurement while differing in stroke or mounting hardware. Begin with the exact frame variant and size, then document the complete specification before asking a supplier to identify a compatible replacement.

Read Santa Cruz Blur shock dimensions as a complete set

The LT1 support record lists approximately 200mm eye-to-eye and 57mm stroke. The XC1 record lists 200mm and 50mm for medium and large frames. The shared first number does not erase the different stroke, nor authorize moving one shock between those platforms.

XC1 also has a frame-size exception: extra-small and small use a 165mm eye-to-eye shock with 38mm stroke in the manufacturer’s table. A listing that says only “fits early Blur” therefore leaves out a decisive part of the identification. Include the frame’s size in every parts enquiry.

Write down the front and rear hardware separately

For LT1, the archived front bushing width is 22mm with an 8mm bolt. At the rear, the record gives an 18mm width and a 3/8-inch bolt, expressed there as 9.53mm. Those ends are not documented as identical. Do not round the rear bolt into an 8mm fitting because that number is familiar.

As a distinct later example, Blur 3 lists a 170mm eye-to-eye shock with 35mm stroke and 20x8 hardware at both ends. These differences illustrate why a generic Blur shock description is inadequate. They do not identify which shock is installed in the orange photograph.

Ask for an approved combination, not just a matching advert

Send the frame designation, production range, size, shock markings and both hardware descriptions to the supplier or rider-support team. Explain any known replacement history. The installed shock could itself be a previous substitution, so it is not automatically the final authority on what the frame accepts.

A proposed damper also needs appropriate physical clearance and a suitable application. Matching the main dimensions is a necessary identification step, not a complete approval of every shock body or tune. Have the full assembly assessed rather than increasing stroke to obtain more travel without frame authorization.

Santa Cruz Blur shock dimensions FAQ

Can a 200mm shock replace another 200mm shock automatically?

No. Stroke, mounting hardware, clearance and frame approval must also match.

Does XC1 use the same shock size for every frame size?

No. Its support record separates XS/S from M/L.

Should the two mounting ends be ordered as one assumed size?

No. Record each end individually; the LT1 table documents different front and rear interfaces.

A reliable Santa Cruz Blur shock dimensions record names the frame, size, eye-to-eye, stroke and both mounting ends. That detail prevents a superficially matching component from becoming an expensive compatibility mistake.

After the complete damper is confirmed, the Santa Cruz Blur suspension sag guide explains how its setup question differs from a parts measurement. Further references are grouped in the Santa Cruz bicycle collection.
