Used Strange Engineering Lightweight Pro Race Spool. P/N D1549. For 12-bolt, 4.11 and numerically higher ratios, 33-spline axles. it had roughly 10k miles on it before it was removed. Unfortunately, i do not have any paperwork for it. i got the part number straight from the side of the spool and crossed referenced it to Strange's website, then spoke with a rep for verification.

new it's $189.50
asking $90+shipping
