Ultimate Quality Steel Shock spring. Getting the correct spring weight on your coil shock is crucial and can make the difference in getting the best out of your suspension. The Nuke Proof Shockwave Oversize spring has a 36mm inside diameter and will fit most oversize shocks including, Fox DHX coil, Manitou Swinger Coil, Progressive 5th Coil.
How do I choose the correct size?
There are three important things you need to know about your set-up:
The Stroke of your shock - This is the actual travel of the shock itself. To measure this, measure the visible part of the shock shaft in Inches 1" = 25.4mm (This is the part that disappears as the shock compresses)
The Maximum Spring Free length that your shock will take. To do this wind the preload off completely and measure from the inside of the spring collar to the inside of the preload nut.
Spring rate in Lbs. - Spring rate refers to the stiffness of the spring and will vary due to rider weight, riding style/discipline, Leverage ratio of the bike, and suspension design. As a general rule you are trying to achieve the correct amount of sag. Sag is the amount your suspension travels when you're sitting on your seat, feet on your pedals and hands on the bars. This should be around 1/3 of the total travel on a DH bike and 1/4 of the total travel on an XC All mountain bike (This can vary due to suspension design and personal preference)
Once you have established the answer to 1, 2, 3 you need to choose your spring using the following rules:
Spring Stroke should be Equal to or Greater than Stroke of the shock
Spring Length should be less than the Max Free length of the shock (This is so the spring physically fits)
Spring Rate should be correct to suit your body weight, bike and riding style
Example. If your stroke is 2", your rate is 450Lbs and your max free length is 130mm.
You need - 2.25" x 450Lbs x 125mm i.e - If you don’t see a spring that has the exact stroke of your shock you can use a spring with a longer stroke, as long as the free length will fit.
Rated 4 out of 5 by Anonymous Heavy but good
I bought one in 400x2.25 size. Real weight is 50% higher than below (mine weights 401g instead of 266g) but still I thing its doing its job well.

Rated 5 out of 5 by Anonymous Just as goodwill as Fox
Works perfectly, quality seems identical to the more expensive Fox Shox original springs.
Buy with confidence!

I just bought this for my 2007 Kona Stinky. It came with a Fox Van R Hope, the 500 - 2.75 fits and is softer than what I had before. Also £35 isn't that bad.
