Looking through the forum it looks like a 2.25 also the spring touching the frame on the medium, is there a bigger gap on the large frames

Has anyone fitted a coil shock on a Sam2??

Here we have a Marzocchi coil shock with a 500 spring on the large jam2, 4mm clearance on the frame and it rides superb.

Hi Billy - how does bomber CR spring feel compared to super deluxe? Is there enough mid stroke support and bottom out resistances? I’m in Santa Cruz CA also have Jam2 thinking of doing same swap. Not sure about spring weight or mounting hardware needed. Let know what fox hardware you ordered and spring. I’m about 185, 195 geared up and I ride hard techy stuff fast.

Hi, I am 165, I took in to consideration the weight of the bike. A 500lb spring and no headwear required . It feels better than the fox dpx on square edged hits, it also climbs better on steep rough climbs. Better all round shock imo. Also The Tec pac has plenty of room as some people don't think there is. Hope this helps.

So I got an interesting reply regarding this. I had seen that they have previously said its down to the FOLD suspension they don't recommend coils but the new Sam2 29er runs one.
I asked:
Hi, Is it possible to run a coil in the Jam2? I see the new Sam2 comes with a coil. I've also seen that Marco Fontana's Focus Jam2 runs a coil shock.
Focus:
the JAM² is developed for Air Shocks only. We never planned to run Coil Shocks on that bike. Nevertheless, there could eventually be some models on the market that could fit. In general the clearance (around the shock itself) is good for air shocks, but not enough for coil shocks. Coil shocks have a bigger cross section. So in the end it´s up to you ... if you find a model that can fit in without collision and good enough clearance, give it a try. But we don´t recommend to do so ... just because it will be hard to find one that can fit with secure clearance.
Best regards

Has anyone fitted a Fox DPX2 or Rock Shox Superdeluxe. Concerned about piggyback. Thanks
Hi
I have.
2020 Jam2 Bosch CX and Fox X2 fitment
So, does it fit or not as the air can seems pretty bulky? If not, what about other shocks with piggyback like Mara Pro or DPX2 (upside down ofc). Do the piggybacks fit or does it get caught by the downtube? The stock Fox DPS is almost as bad choice as the 34 Rhythm fork for this kind of a bike.

Does anyone know if the 2021 Jam2 frame has any better clearance for piggyback coil shocks? I've got a brand new MRP Hazzard 210x55mm shock looking for a new frame!! I do know that the MRP coils are 38mm inner diameter, so a bit larger than CC and Fox.
Thanks

Thanks

My understanding is that frame it self is same than 2020

I bought a fox dhx 2022 shock and can confirm that doesn't fit 
its going back to the shop next week so guess I will either have to go ohlins or a dpx can...gutted as I was looking forward to trying out the new coil this weekend.
its going back to the shop next week so guess I will either have to go ohlins or a dpx can...gutted as I was looking forward to trying out the new coil this weekend.Hi all, I've got a 2017 Jam2 Plus with 27.5 wheels which originally had a Revelation 140mm up front and RS Deluxe on the rear, I fairly quickly switched to a Yari 160 mm and then added an old Fox DHX5 200x57 coil that i had lying round. This setup was way better then the original and much plusher on the rear. Then about 1 year ago i played round and found out i could probably fit a 216x63 coil on the rear if i used offset shock hardware - so ordered a Bomber CR with Valt spring, fitted it on and now have 160 mm on the rear, and no frame rub with the coil. I also switched the Yari air shaft out for a Smashpot and this machine is ooohhhhh so plush now - a completely different beast to the original and awesome for enduro trails - i'd never go back (and i'm nearly out of warranty period so not worried about that either). If anyone is interested i can put some pic's up.
Cheers

One thing to note i have an L frame and not sure this works for M frames
Focus Jam2 - Suspension - Rear Coil Shock & Front Fork Upgrades
Marco Fontana's Focus Jam2 - Ohlins Rear Shock and Front Fork, plus other mods. Looks great IMO. Not that he would need to worry but when I enquired to Focus re: suitable rear shock, they advised the only one that was tested were the factory fitted models and anything else may void warranty...
