Hendrickson LoneStar, ProStar, TranStar, 9200, 9400 2011 Parts Catalog

I’ve been turning wrenches for 28 years, and I’ve seen more parts catalogs than I care to remember. Most of them are junk – aftermarket reprints with wrong part numbers, blurred diagrams, and missing details that cost you time and money. This Hendrickson LoneStar, ProStar, TranStar, 9200, 9400 2011 Parts Catalog is the real deal: factory-issued, 20 pages, built for the trucks you work on every day. It covers suspension systems – SOFTEK, 2-Leaf, and AIRTEK – with exact part numbers and exploded views. No guesswork, no hunting for obsolete cross-references. You need to order a shock absorber for a 2011 ProStar? You’ll find it on page 3 with the correct bolt torque and locknut spec.

SOFTEK Monoleaf: Parts Exploded Views

This section starts on page 2 and covers the SOFTEK monoleaf spring assembly for models built after August 1, 2011, with the STEERTEK NXT axle. You’ll see the shock absorber, spring assembly (part number 53297-000 for LoneStar and ProStar, 53297-008 for TranStar), and the entire steering knuckle breakdown. Every bolt, locknut, and washer is listed with its size – 5/8″-11 UNC, 3/4″-10 UNC – so you don’t have to pull a bolt and run to the hardware store. If you’re working on a truck built before that date with the standard STEERTEK axle, flip to page 6. Same level of detail, different part numbers.

2-Leaf Mechanical Suspension: What Models Are Covered?

Pages 8 through 13 cover the 2-leaf mechanical suspension, which shows up on ProStar, TranStar, and LoneStar in various weight ratings: 12K, 12.35K, 13.2K, 14K, and 14.6K. For the older 9200, 9400, and 8600 models, you only get the 12K rating on the STEERTEK axle version (page 12). That’s important – don’t order a 14.6K shackle plate for a 9200; it won’t fit. The catalog breaks it down clearly by axle type and build date. The exploded view on page 8 shows the rear spring mount, shackle plates (part 66545-000), and the 3/4″-16 UNF bolts with locknuts. If you’re swapping leaves, those torque values are in the service manual, but this catalog gives you the correct hardware identification so you can order the right parts the first time.

AIRTEK System Breakdown After 9/06

The AIRTEK section (pages 14-19) splits into New Engine Configuration (NEC) for trucks built after September 2006 and Prior Engine Configuration (PEC) for older trucks. You also get the Dual Height Control Valve Conversion Service Kit on page 18 and a PEC Replacement Service Kits Reference on page 19. This is where the catalog saves you a headache – the height control valve routing changed with the NEC, and using the wrong kit can screw up your ride height. The PEC Component Replacement Guide is right there on page 19 as well. No flipping through bulletins.

STEERTEK NXT vs STEERTEK Axle: Know the Build Date

Every section in this catalog is split by axle type and build date. Anything after August 1, 2011 uses the STEERTEK NXT axle; anything before uses the standard STEERTEK. That cutoff matters because the spring seat, shock bracket, and knuckle components are different. If you’re rebuilding a 2011 LoneStar built in July, you’re on page 6. If it rolled off the line in September, you need page 2. Ignore that date and you’ll order parts that won’t bolt up. This catalog makes it impossible to screw that up – the headings are bold and explicit.

20 Pages of Factory Parts Lists

Twenty pages doesn’t sound like much, but every page is packed with part numbers, quantities, and notes. This isn’t a reprint from some third-party scanner – it’s the original Hendrickson SP-182 revision D, dated December 2011. The diagrams are clean, the type is legible, and the index at the beginning tells you exactly where to go. For background on how suspension systems evolved, you can read the Automotive Industry Overview on Wikipedia – but for real work, you need this paper (or PDF) in your hands.

You don’t need a subscription service or a login. One access, and you’ve got the same data the dealer parts counter uses. Aftermarket catalogs often skip the torque specs and washer counts – this one gives you every locknut and flat washer. I’ve seen guys strip shock bolts because they bought a generic “equivalent” – not with this catalog.

Who should buy this? If you maintain a fleet of International trucks with Hendrickson suspension, or if you’re a DIYer swapping a spring pack on your own LoneStar, you need this. Don’t rely on aftermarket parts websites that cross-reference by VIN alone. Use the factory part numbers from this catalog, then order with confidence. It’s also useful for shop owners who want to keep their techs from guessing.

Why trust an OEM catalog? Because Hendrickson engineered the parts and printed the book. The part numbers match the engineering drawings. Third-party catalogs sometimes use supersession chains that skip intermediate revisions – that gets you the wrong kingpin bushing. This catalog is the source. If you’re ever unsure about a build date or axle configuration, cross-check with the Automotive Industry Overview for general knowledge, but for hard data, stick with Hendrickson.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists fastener sizes and part numbers, but not torque values. You need a separate service manual for tightening specs. However, the bolt grades and locknut types are given, so you can look up the correct torque in the service manual.

Will this cover a 2011 9400 with the 2-leaf suspension?

Yes – the 9200/9400/8600 models are listed on page 12 (STEERTEK axle, prior to August 1, 2011) with 12K capacity. If your truck has the 2-leaf suspension and STEERTEK NXT, it’s not covered – those axles only appear on the newer models. Check your build date.
