Associated V2 Big Bore Spring Conversion
These days, big bore shocks are all the rage when it comes to dialing your suspension. Paul Sinclair, of X Factory RC, came up with an interesting solution for having all the benefits of big 
bore springs without the added weight of big bore shock bodies. He claims that using big bore springs on a standard size shock body is the best overall setup for shock performance. The idea is that big bore springs can be placed on smaller bore shocks in order to prevent scraping. Scraping is a very common issue when it comes to standard size shocks, which can result in an inconsistent feel. Smaller springs buckle as they compress which can allow them to actually touch the shock bodies and cause friction. Because big bore springs have a much larger diameter, they are much less prone to scape than their smaller counterparts. I can personally vouch for this method as I have been very impressed with my t4.1’s handling after doing this simple mod. My shocks feel very smooth.
Now, there is one issue with putting a big bore spring onto a smaller shock such as the Associated V2—The spring is too large for the shock collar and spring retainer. This can easily be remedied by using Traxxas part number 3768. This bag of parts has a larger spring retainer and shock collar, which will fit the big bores perfectly. A small amount of demeling will be needed to fit the spring retainer over the associated V2 shock end, but this only takes seconds.

Note if you are unfamiliar with big bore springs for stadium trucks, I would suggest trying the following springs as your starting point:
Front: Losi Green 22 front springs
Rear: Losi Yellow 22T rear springs
