Suspension oil

I know Gray will have the answer on this one.

What weight oil should i use for forks and shock.

I am used to 5 weight on showa in the forks,

2.5 on the shock

KYB need advice!!!!!!!!!

My first choice is to use 215.VM2.K5 fluid from SMART Performance. Use SPI #3 in the shock and in the inner fork cartridge, and the heavier SPI #5 in the outer chamber of the fork.

Second choice in Amsoil Shock Therapy #5 Light in the shock and fork cartridge, and #10 medium in the outer chamber.

Running the heavier oil in the outers allows you to run a slightly lower oil level but still resist bottoming.

Penske Racing's MX and ATV division, called Axis Racing shocks, runs proprietary fluid in the shock and Bel Ray fork Oil 3W up front. They tested everything on their shock dyno's and nothing else worked as good in the forks. Not even their own fluid, which wasn't suited for the forks.

I think they know a thing or two about suspension. They build all of their own shocks for Indy, Nascar and MX/ATV. I'm not sure if they sell their fluid to the public, but its in my stuff after they revalved and serviced my suspension.

I second that.:smirk: That Del Taco kit is sweet and really makes a difference on a 2010 YZ450.
