NOTE: for 35 & 40 Spline Steel Spool applications, if you are replacing a Mark Williams or other manufactures spool check your spline location! The Moser Standard Steel Spools have splines are located inboard not out under the bearings like Mark Williams and other manufactures, your passenger side axle will be too short and not engage the spool. Please select "Pro Steel 40 Spline Spool" at the bottom of the "Differential Options" if you have determined you have a 40 spline spool that fits this criteria.

Product Description

Moser's Custom built 9" & 9 1/2" FORD Center Sections are assembled with Timken bearings. Solid Pinion shims are used instead of the weaker crush sleeves. All units are assembled with special calibrated "Torque Guns", which means no impact guns that will hammer and flat spot bearings and no guessing on your pinion nut torque setting! Each pinion is specifically torqued to the gear manufactures stated setting.

All Center Sections are assembled with the following Moser Engineering designed and manufactured components;
Pinion Supports
Pinion Yokes

Items that are part of the Center Section that are assembled but sourced from an outside supplier;
Bearings (TImken) & Seals
Fasteners (all grade 8)
Limited Slip Differentials
Ring & Pinions (Gears) - Moser Engineering does not manufacture any gears! These are sourced but not limited to the following suppliers; US Gear, Hoosier Gear, Motive/Richmond Gear & Yukon Gear

**Light Weight Aluminum Spools and Pinion Yokes are designed to be used in light weight racing applications (<2000 lbs.) only! These items also are considered wear items and should be monitored and replaced periodically.

Moser has changed their website to reflect the Motul gear oil as their recommended fluid for all gear type LSD’s (this includes Truetrac’s). Gear type units require friction to work properly. Most aftermarket oils have additives that helps to alleviate heat, wear and prolong life. In doing so these additives minimize friction causing gear driven units to be less efficient and sometimes fail completely.
