Spartan K2 Chassis RV Windshield Replacement

Spartan K2 and K3 chassis sit under premium Class A coaches — Newmar Dutch Star and Mountain Aire, Entegra Aspire and Anthem, Foretravel — which use some of the largest curved laminated panels in the RV market. Replacement runs $1,800–$4,200 installed for a two-piece set, with 7–20 business days to source glass because most panels are built to order by the coach maker.

Why Spartan-based coach glass costs more

K2 and K3 chassis carry the widest and most steeply raked front caps in the industry. Bigger panels mean more curvature, thicker laminate, and higher scrap rates at the glass plant — which is why a Newmar Dutch Star panel can cost double a comparable Class A panel on a smaller chassis.

Many of these coaches also run heated or acoustic-interlayer windshields, and the wiring pigtail must match the coach harness. Substituting a plain laminated panel loses the defrost grid and can trigger dash faults.

Panels frequently exceed 60 inches on the long edge
Heated windshield options on cold-climate builds
Acoustic interlayers standard on many 2018+ luxury coaches
Freight is crated and often LTL-only — factor 3–7 extra days

Single panel: $950 – $2,300 installed
Two-panel set: $1,800 – $4,200 installed

Crated freight on 45 ft panels: $150 – $400

Sourcing a Spartan-chassis panel

Start with the coach builder's parts desk for the current part number, then price the same number through an RV glass specialist and an independent glass distributor. On discontinued coaches, a specialist can often cross-reference to a shared panel used across model years.

Have coach brand, model, floor plan, model year, and VIN ready
Photograph the frit band — part numbers are often etched in the corner
Confirm heated vs non-heated before ordering
Ask whether the quote includes crated freight and liftgate delivery

Spartan K2 / K3 Glass FAQs

How much does a Spartan K2 RV windshield cost?

$1,800–$4,200 installed for a two-piece set, or $950–$2,300 for one side. Heated glass adds $300–$900 per panel.

Why is the lead time so long on Newmar and Entegra glass?

Most large curved panels are built to order in batches and shipped crated by LTL freight. Seven to twenty business days is normal; hail season can push it past 30.

Can Spartan supply the windshield?

No. Spartan builds the chassis; the windshield is part of the coach builder's front cap. Order through the coach brand or an RV glass specialist.

Is mobile service possible on a 45 ft Spartan coach?

Yes, and it is usually preferred — moving a coach with a cracked structural panel is riskier than bringing two technicians and a glass lift to the rig.
