Freightliner FLD112, 120 Parts Catalog – Why This OEM Manual Belongs on Your Bench

I’ve spent 28 years turning wrenches in San Antonio, and if there’s one thing that burns my ass, it’s watching a guy order the wrong part because he trusted an aftermarket parts list that combined three different model years. You pull the old u-bolt, the new one shows up half an inch short, and now the truck sits on stands while you run to the dealer. That’s billable time you’ll never get back. The Freightliner FLD112, 120 Parts Catalog stops that nonsense cold. This is the same catalog the Freightliner dealership parts counter uses, and it covers front suspension components for 3.5-inch wide springs on the FLD112 and 120 models. It’s 16 pages of factory-issued part numbers, keyed to exploded-view illustrations, so you order exactly what your truck needs the first time.

Front Suspension Parts for 3.5″ Wide Springs – What’s Inside

Page 2 of this catalog lays out the front suspension parts for trucks and tractors using a 3.5-inch wide spring pack. You get Euclid numbers and Freightliner numbers side by side: spring eye bushings (threaded and non-threaded), front spring pins, rear spring pins, u-bolt assemblies with specific thread pitch and length, axle shims in 2° and 4° increments, spring hangers, shackles, and shock absorbers including the Fleetline and GasSLX shocks for the FLD112 and 120. Every entry includes a quantity-per-axle column so you know how many to order. The illustration on the same page shows exactly where each part goes. No guesswork.

6 Systems Covered – From U-Bolts to Shackles

This catalog isn’t a service manual—it’s a parts ID book. But it covers the six main areas of the front suspension you’ll need to maintain: spring eye bushings, spring pins (threaded and non-threaded), spring hangers and shackles, u-bolt assemblies (Rd. Bend, 3/4-16 thread, lengths from 10 to 18 inches), axle shims for caster correction, and shock absorbers with cross-reference numbers. For the FH34 suspension (page 3–4), you get lightweight steel tubular rods, equalizer bushings, torque arm shims, and spring references for 3-, 6-, 7-, and 8-leaf packs. If you’re doing a full spring rebuild or swapping a cracked hanger, this catalog tells you the exact part number you walk to the parts counter with.

Why This Parts Catalog Beats Aftermarket Lists

Aftermarket catalogs love to combine years and make assumptions. They’ll list “fits 1990–1995 FLD112″ but skip the sub-variants like threaded vs. non-threaded bushings, or the difference between a 10″ and 12” u-bolt. This OEM catalog splits those details. Look at page 2: key number 1 shows E-3533 for non-threaded bushing, key number 4 shows E-3534 for threaded bushing. They look similar, but mix them up and the spring pin won’t seat. I’ve seen guys hammer a threaded pin into a non-threaded bushing, ruin both, and then blame the parts supplier. The Freightliner catalog eliminates that amateur hour. The source document is a verified factory scan—no third-party reprint, no digitized copying of a copy.

How to Use the E-Number Index

The manual’s index lists every E-number (like E-3533, E-8795, E-UB8154-10) and references the page where that part appears. You don’t flip through blindly. If you need a u-bolt for a 4-inch-wide spring, you find E-UB8164-12 in the index, turn to page 3, and get the Freightliner number 11-09624-120. That number is what you call the dealer with. Keep this catalog in your toolbox for any FLD112 or 120 you work on. It also covers the FH34 suspension, so if you’ve got an older Freightliner with that setup, you’re covered.

Who Needs This Manual – DIY Truck Owners and Small Shops

If you’re a home garage guy working on your own FLD112, you don’t have a parts manager on speed dial. You need to order parts online or over the counter, and one wrong digit sends you the wrong bushing. This catalog gives you the skill to identify parts by actual OEM numbers, not aftermarket cross-references that might be obsolete. Small shops with two lifts can’t afford to have a truck tied up waiting for a return. Having the factory parts catalog on your tablet or printed out reduces downtime. The automotive industry depends on accuracy in specifications, as noted in the Automotive Industry Overview. For background on the engineering of these components, the Internal Combustion Engine is a broader topic, but for suspension parts, this catalog is your specific tool.

FAQ – Freightliner FLD112, 120 Parts Catalog

Does this catalog include torque specs for suspension bolts?

No. This is a parts catalog, not a service manual. It lists part numbers, descriptions, and quantities. Torque values are not included; you need a separate Freightliner service manual for that.

What exact models are covered?

Freightliner FLD112 and 120 trucks and tractors with front suspension designed for 3.5-inch wide leaf springs. Also covers the FH34 suspension system on some models.

How can I verify that a part number in this catalog fits my truck?

Compare the Freightliner number (e.g., 16-1005-000) to the part you remove. Use the key number and the illustration on the page to confirm location. Cross-check with your axle serial number if possible. This catalog is the same one dealers use, so if the number matches, the part fits.

Is this a reprint or the original OEM document?

This is a direct, unaltered scan of the original Freightliner factory parts catalog. It is not a third-party reprint, not a compilation of multiple sources. The 16 pages come from the OEM manual, published by Freightliner for internal dealer use. That means the part numbers, descriptions, and exploded views are exactly what Freightliner issued. No aftermarket house has touched it. When you source a part from this catalog, you are working with factory data, not a guess. I’ve seen aftermarket catalogs list a single bushing for all years and then you end up with a threaded bushing when you need a smooth one. This OEM document separates those details—threaded vs. non-threaded, length of u-bolt, degree of shim. That level of specificity keeps your rebuild on schedule and your truck off the hoist.

Access the Factory Manual and keep this 16-page parts catalog in your shop. Every u-bolt, bushing, and shim you order will be the right one. I’ve been doing this long enough to know that guessing costs more than the manual. Get it, use it, and stop wasting time on wrong parts.
