There are more Cascadias on the road than any other Class 8 truck — and two distinct generations that do NOT share front-end parts. This guide sorts every body part by generation, with the OEM cross-references, so you order the right part the first time.
Quick answer: the #1 Cascadia repair we ship is the hood hinge (17-20555-000) — if your hood has started bouncing or sits crooked on a 2009-2018 Cascadia, that's the part, and it's in stock.
Which Generation Is Your Cascadia?
| Generation | Years | Front-end family |
|---|---|---|
| Cascadia / Cascadia Evolution | 2008-2017 | A06-51907 headlights, A21-28546 chrome bumper |
| Next Gen Cascadia | 2018-present | A66-01405 headlights, A17-20832 grille |
Fastest tell: Next Gen has the sleeker swept-back headlights and aero grille; 2008-2017 has the upright rectangular lamps.
The Hood Hinge (Most-Replaced Cascadia Part)
Cascadia Hood Hinge with crossbar — 17-20555-000 — fits 2009-2018 (old generation). When the factory hinge wears, the hood bounces at speed and eventually cracks at the mounts — a painted-metal hinge protects a $3,000 hood. In stock, ships in 24h.
Next Gen (2018+) Front End
- Front Bundle 2018+ — complete grille (A17-20832-013 pattern; also covers -008/-012/-014/-016/-017 references) with both side corners, ABS with metal bug screen, DOT approved.
- LED Optical Headlights 2018+ — A6601405002 / A66-01405-004 family, cross-refs 564.46001MK, S-29601/S-29602. (Restocking — search the part number on our site for current availability.)
- Black Door Mirror Assembly — A22-73907-006/-007, heated & powered.
2008-2017 Front End + OEM Cross-Reference
| Part | OEM / Reference # | Notes |
|---|---|---|
| Headlight — halogen | A06-51907-006/-007 family (-000, -002, -003, -004, -004F) | Multiple styles, one mounting |
| Headlight — LED projector | same A06-51907 fitment | Brightest upgrade |
| Headlight — optical lens | same fitment, 564.46058 | Chrome housing styles |
| Chrome bumper | A21-28546-019 / -020 | 2008-2017 |
One fitment, five headlight styles (halogen, halogen projector, LED projector, optical, LED optical) — every 2008-2017 Cascadia takes the same mounting, so you choose by look and budget. These sell through fast; check the Freightliner collection for live stock by style.
Cascadia vs M2 — Don't Mix Them Up
The M2 106/112 (the smaller business-class Freightliner) uses completely different parts — M2 mirrors 563.46025C, M2 corner bumpers 2126517-000F. If your title says M2, use the M2 pages.
Frequently Asked Questions
What headlight fits a 2019 Cascadia?
2018+ Next Gen lamps — the A66-01405 family (A6601405002-pattern). The 2008-2017 A06-51907 lamps will NOT fit a 2019.
What headlight fits a 2015 Cascadia?
The A06-51907 family — available in halogen, projector, LED projector and optical-lens styles, all on the same mounting.
My hood bounces at highway speed — is that the hinge?
Almost always yes on 2009-2018 Cascadias. Replace in pairs if both sides show wear; it's a bolt-on job.
