How long is the limitations period on this written contract, and can the contract change it?

Four years for an action upon any contract, obligation or liability founded upon an instrument in writing (Code Civ. Proc. § 337(a)), except as provided in § 336a, which gives SIX years for an action upon bonds, notes or debentures issued by a corporation and issued to or held by the public, or upon the mortgage, trust deed or other agreement under which they were issued; and § 337(a)'s own proviso confines an action for a money judgment for the balance due, after exercise of a power of sale in a deed of trust or mortgage on real property, to three months after the sale. As to EXTENDING it, the contract cannot do so open-endedly: no waiver bars the limitations defence unless it is in writing and signed by the person obligated; a waiver executed before the period expires is effective for no more than four years from the date the period expires, one executed afterwards for no more than four years from its own date, and such waivers may be renewed for further periods of not more than four years each (§ 360.5). Section 337 has two more clocks: four years for a book account, an account stated in writing, or a mutual open and current account, running from the last item (§ 337(b)); and four years for an action based on the RESCISSION of a written contract, running from the facts that entitle the party to rescind, or, where the ground is fraud or mistake, from their discovery (§ 337(c)). The period is extended only under § 360: no acknowledgment or promise takes the case out of the statute unless it is in a writing signed by the party to be charged, though a payment of principal or interest on a promissory note restarts the period on that note as each payment is made, and no payment revives a cause of action once barred. A contract NOT founded on a writing gets two years (§ 339(1)), and a contract for the sale of goods four years under Commercial Code § 2725, which the parties may reduce by original agreement to not less than one year but may not extend, accruing on breach regardless of knowledge and, for warranty, on tender of delivery unless the warranty explicitly extends to future performance of the goods and discovery of the breach must await that performance, in which case it accrues when the breach is or should have been discovered.

The trap

A tolling or 'the parties agree not to plead the statute of limitations' clause signed at the outset is not a permanent extension: it is a four-year waiver that must be signed by the obligor and then RENEWED, and an unsigned or unrenewed one leaves the defence intact. Note also § 337(d): once the period has run on a debt, a person shall not bring suit or initiate an arbitration or other proceeding to collect it, and the period may be extended only pursuant to § 360. And the goods contract is the exception to the § 360.5 route: Commercial Code § 2725 says in terms the parties "may not extend" its four years, so a tolling waiver that would work on a services agreement does not lengthen the sale-of-goods period, while § 2725 expressly permits the parties, by original agreement, to reduce its four years to not less than one year: a permission § 337 does not state, and a clause shortening the period is a different question from § 360.5's waiver cap: parties may agree, in an arbitration agreement or otherwise, to shorten the limitations period applicable to a claim, but the shortened period must be reasonable, and in Jenkins a one-year cut imposed on a four-year statutory claim was not.
