Hi just purchased the above bike, finding the rear shock a bit weak I’m not the lightest of people 103kg.
Can anybody recommend a replacement spring that will be more suited to my weight.

Links to any websites would be great

cheers

Is 103KG your riding weight, with pack etc? If so, you need a spring of 600lbs to 650lbs depending on how much sag you want.

Phone TF Tuned up and ask them because I bought my Kenevo comp XL and it came with a 550lb spring on it (FOX Van Rc Coil) that was way too soft as I am the same weight as you
I went for a 700lb spring which I bought from the TF Tuned website and the correct one for the Shock but it turned out to be too long even though it was a Fox 2.8 same as the one already on it .I phoned them up and they said that that shock will only take up to 550lb springs in the Fox range and I needed to buy an Ohlins shock as they are shorter than any other
 
Old kenevo or new ? Makes a difference. At about 100kg the 650lb on my van doesn't sag enough. The max spring length can be about 6.1". I'm trying to get a 600 x2.5 as the 2.8 is too long.
 
You need a 600lbs spring
FWIW, I've got about 10 pounds on you, and couldn't get enough compression to stop the thing from racing to bottom.
It also managed to eject the shaft(must've broke the clip that holds it it). The shaft also got bent, but I imagine that was a result of it forcibly removing itself, as opposed to bending, then ejecting. I'm not gonna even bother with repairing it. Just going straight to a DHX2(with a temporary stop with an X2 while I'm waiting for the Fox coil to show up).
I've found nothing redeemable with either Marzocchi(read: CHEAP Fox) pieces on the bike.

I meant spring when I said I got an Ohlins shock
This was for a 2019 Comp
So the Ohlins spring is a lot shorter then the fox
So it goes nicely on the Van RC and it’s Yellow which is a bonus I like

Because of the 57mm stroke of the shock and the eye to eye length the only brand I found that will fit on Springs over 550lb is the Ohlins ones as they are physically shorter.This one you will not be able to put the end cap on without having to use a spring compression tool ,which then you may not be able to set your sag correctly

Phone TF Tuned Up they will advise you the best weight spring for you and your riding style and send you the correct one and yes it’s £95 ( Ohlins one , don’t know if there is a cheaper alternative)but you are paying for the spring and the correct information and a spring that will guaranteed fit and a warranty ( and no I’m not on commission )

20 Kenevo? The OE Marz shock is simply a Fox Van. You have 62.5mm of stroke(shimmed down from 65mm) which translates to 2.4" of stroke. You therefore want a spring that has NO LESS than 2.4" of stroke, but you can go with a little more, cuz you've got the room on the shock body.
I was running a 2.8" stroke spring on my Marz before I broke it, so, yeah. You'll be fine.
FWIW, if you're in SoCal, you're welcome to my spring. I've switched to a DHX2 and an SLS spring.
If you are local and want it, just PM me

I got told the same from them but found a few others had used the cane creek vault with no issues so that's what I got and half the price of an ohlins no issues so far ?
 
What sag to you get? I recall 19mm or so is 30% on these. I only get 14mm so will drop to a 600 when there is stock in the UK again.

Fox is of the opinion it should only take two full turns to get 30% on the correct spring too, which I don't think I've every been able to do .
IMO You know you shouldn't be cranking the living piss outta the preload collar, and conversely you know if you only get one turn, then time to go lighter

This is what I’m sending to fox after my dhx performance failed this weekend on my kenevo Good evening I purchased a Specialized kenevo In May 2024, September 2025 the rear shock failed and after speaking to you guys you said to bring it down as there was a two year guarantee I was very impressed with the level of service I received as the shock was rebuilt and given back to me within 48 hours, which I thought was an amazing level of service in November 2025 I had to have an operation which has seen me off the bike for the best part of five months before the operation after the work was done on the shock. I probably only had about three or four hours of use then had the operation and I’ve only been back on the bike since the middle of March since being back on the bike. It’s probably only had around 5 to 6 hours of use after going out for a ride today and as I’m still recovering I’m not riding anything too dangerous and given I’m a 40-year-old man with a mortgage and two children and I’m not young anymore I don’t ride Big jumps or Big drops or anything like that I went for a ride today just doing a loop of Swinley Forest on the blue trails and two trails from the car park I started to hear a loud clunking banging noise coming from the rear shock when it compresses. I’ve also noticed that the lockout lever has now got a bit of a rattle and there was some oil residue on the shaft. The preload is set to 12 clicks and when this happened last time the same sound came back this time I’ve decided not to ride the bike anymore as it’s already starting to fail and I cannot risk it braking and me crashing undoing all the work that’s been done in the operation that I had after looking on the Internet I’ve discovered that this shock was discontinued due to Reliability issues in last 2025 and given the fact that still less than two years and is the second failure I would like to know what you could do to help. The rear shock is a Fox DHX performance 230x 62.5. Many thanks, and I will be giving you guys a call in the morning when you’re open thank you
