K4 Rocket fins
The K4 Rocket fins are the best choice when you’re looking for power from your wave fins.
These give great lift, drive and speed for onshore conditions. They’re also great for early planing and jumping.
Their DTL (Down The Line) performance is fantastic too, but you’ll need to use your rails more aggressively for powerful turns as they don’t have the same grip’n’whip in big cut backs and snaps as with the flexier K4 fins.
The smaller rocket sizes are designed to be used as front fins for tri and quad fin setups, or as rear trailer fins where the upright and non swept template is ideal.
The K4 Rocket fins are the best choice when you are looking for power and speed from your wave fins.
The K4 Rocket fins are like having slalom fins in your wave board! When you need power and speed from your quad, or from your front fins on your thruster, the K4 Rocket is the fin to have. This fin also works great as a trailer fin.
These are great for onshore conditions where maximum drive is ideal.
ORDERING AND LEAD TIME
We supply these as PAIRS of fins…NOTE: you are ordering a PAIR of fins. (If you just need 1 no. fin, please email us.)
Sizes 8-13cm are fronts, while 14.5-20.5cm are available in the rears.
There are more than 20 different variants on this model fin. For this reason Bigsurf and also K4 themselves, can struggle to hold stock of each different size/fitting, all of the time. But we do have the more popular sizes in stock, so chances are that YES we do indeed have the fins you need in stock.
However if for some reason we don’t, we can have the guys at K4 send them to us within a few days. And even if K4 are sold out, we can see when they are doing a production run next…OR there may be an alternative fin that will work for you also as the range is large.
So if we don’t have what you need, we will contact you to discuss very soon after receiving your order and checking our stock.
TERMINOLOGY ON K4 FINS
These ratings are to compare K4 Fins only. K4 fins are lighter, looser and grippier than anything else on the market with test-winning performance. This fin guide will help you dial in your board for ultimate performance.
RELEASE/GRIP: This is a choice you have to make. Do you want to do huge wrapping gouging roundhouse cutbacks with ultimate grip, or would you rather the tail spun more easily into a Taka? Size choice will also affect release.
LOOSE/DIRECTIONAL: Again a personal preference as to whether you like your board to feel loose and skatey, or more directional and on rails or planted.
SNAP/CARVE: Snap and pivot for tight ‘in the pocket’ surfing, or carve for more drawn out turns on open faces. This is related to looseness/control but more to do with template than flex.
LOW DRIVE/HIGH DRIVE: Your immediate thought might be that the more drive the better, right?! Not always the case. Quite often on multifin boards you’ll find yourself flying up at the lip but without the ability to get the board turned, this is too much drive. Of course in slow low power waves and onshore winds drive is a good thing.
