Extensions

Every extensions listing at Second Truck Parts is identified by brand and manufacturer part number, with its condition — new, remanufactured, or used — stated right on the listing. Part of our general & miscellaneous range. Most parts carry our 90-day warranty, returns are accepted for 30 days with an RA number, and our team verifies fitment free before you buy: send your VIN or engine serial and we confirm it fits.

Don't see the exact part? Call (877) 898-0737 (Mon–Fri 8 AM–8 PM ET) or request a quote — much of our inventory comes off salvage trucks in our own yard and may not be listed yet.
