The 27-year-old, who arrived at Upton Park from Wolves in 2012, delivered more crosses than any other Hammers player in the Premier League last term - though played 133 fewer than Everton's Leighton Baines.
Jarvis hopes he can continue to supply the West Ham strikeforce with crosses to attack, even upping his output further, and is eager to form a devastating understanding with towering forward Andy Carroll.

"Hopefully I can supply Andy with a lot this year. If I can keep putting the crosses in, he'll try to win everything in the box, so hopefully that will become a good partnership.
"I need to add more goals to my game from last season, and to keep up the assists."
West Ham owner David Sullivan recently revealed that Sam Allardyce is still looking to add yet more strikers to his squad prior to the new season.
The Hammers are currently on tour in Germany and Jarvis is enjoying the chance to get to know his team-mates better ahead of his second season at the club.
"It's been a good pre-season so far," he added. "It's been very warm, which makes it tough running around in this heat, but it has been going well and I'm looking forward to getting some more games.
"I was a late arrival here last year, so it's beneficial to be here from the start. You go away on tour and you spend a lot of time together - getting together as a team is always important."
Allardyce's side will take on Hamburg on Tuesday and Jarvis could well come up against former team-mate Michael Mancienne.
"Michael was on loan with us at Wolves and he was a fantastic player for us at the time," the England international continued. "I'm sure he'll be very good for Hamburg.
"Hopefully I'll get quite a few minutes in against Hamburg, and really push on."
