Nukeproof ShockWave Steel Spring - 3"

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 Nukeproof Shockwave spring has a 36mm inside diameter to fit Fox, Manitou, BOS coil shock units.

How do I choose the correct size?

There are three important things you need to know about your set-up:

  1. 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)
  2. 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.
  3. 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:

  1. Spring Stroke should be Equal to or Greater than Stroke of the shock
  2. Spring Length should be less than the Max Free length of the shock (This is so the spring physically fits)
  3. 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 2.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by It is a steel spring, and it just works No problems so far in 1 year, installed in my Elka Stage 5 without any issue. 18 August 2014
Rated 1 out of 5 by Poor quality I ordered 2 of these springs, and both were bent. It's not obvious until you put in on your shock and twist it round and one side bulges out. This caused it to rub on both the shock body and the piggy back (on a Fox DHX). Not happy with this at all. - Also the two shocks were slightly different weights - one giving slightly more sag than the other. 22 June 2013

Does it fit?

I use a 350 x 3.25" Fox spring on my Van RC and i want to know if 275 x 3" fits and works fine... it`s 3 mm shorter in length. Or i should go for the 3.5" one?

For maintaining the same feel in a shock it is advised to use the same stroke length or larger.

Using a smaller stroke will decrease effective travel and potentially damage the shock.

Fox measures there spring sizes differently in comparison with other companies. Essentially the 3.00" Nukeproof Spring will fit a FOX SHOX with a labeled spring of 3.25" just fine. I bought and have used a replacement 400lbs x 3.00" spring for a FOX DHX 5.0 and it worked flawlessly.
