What You're Actually Buying
This is a right-hand (passenger side, curbside on most setups - but confirm orientation on your axle) S-camshaft at 23.44" length, 10 spline head, 1.5" diameter. It's the shaft inside the spider that rotates when air hits the chamber, and that rotation cams the brake shoes out against the drum.
Fits Meritor-style trailer axles using this length and spline count - common on a lot of 23K-25K trailer axles running standard Q-plus or similar brake setups. This is not a tractor steer or drive axle cam, it's built for trailer service.
Wear items on these are the bushings/bores it rides in and the roller/cam profile itself. If you're replacing one side, pull the old shaft and measure - don't just go by axle make, go by the number stamped on it or physical measurement.
Why These Numbers Cross & What To Verify
E1094 cross-references to R607001, 2210-Q-6387, CS41523, 41523, 65365, and B1691-26 because all of these describe the same shaft geometry - same length, same spline, same diameter - just different manufacturer part numbering systems (Meritor, Gunite, Webb-style suppliers all number the same physical shaft differently).
The three things that have to match before you order: overall length (23.44"), spline count (10), and shaft diameter (1.5"). Get any one of those wrong and the cam either won't index into your slack adjuster right or won't seat in the spider bushings. Right-hand vs left-hand also matters - it determines rotation direction, so don't swap sides.
Surest way to confirm: pull the old cam and check the number stamped on the shaft end or count splines and measure length yourself with a tape. Cross-referencing off a parts book alone gets people in trouble when trailers have been through axle swaps or brake upgrades over the years.

E1094 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to E1094. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does E1094 fit my Wabash trailer with Meritor axles?
Depends on the axle spec on that trailer, not the trailer brand. Meritor axles used across a lot of trailer manufacturers including Wabash, but you need to confirm 23.44" length, 10 spline, 1.5" diameter off your old cam or the axle tag before ordering.
Is this the same as the Gunite 41523?
Same shaft geometry - length, spline, diameter all match, that's why it cross-references. Different manufacturer stamps their own number on it but it's built to the same physical spec. Still confirm your old part matches before swapping.
How do I know if I need right-hand or left-hand?
Pull the old cam and look at which way it rotates, or check which side of the axle it's mounted on when you're facing the front of the trailer. Right-hand and left-hand cams aren't interchangeable - they rotate the wrong direction if you put one on the wrong side.
