Welcome to the forum, @Lukay67. The Fuel EXe takes a 205mm x 60mm rear shock as standard, with a trunnion mount upper (54x10mm) and pin mount lower (40x8mm).

That gives you 140mm of rear travel paired with the 150mm fork. Trek confirms the following shocks fit: Fox Float X, Fox DHX, RockShox Super Deluxe, and all coil shocks from Fox and RockShox.

Other shocks may work given the generous clearance but should be checked at full compression.

Worth knowing for the future: the frame can handle a longer stroke shock if you fancy more travel. A 205x62.5mm gets you roughly 146mm rear travel, and a 205x65mm gets you up to 152mm. @Endoguru noted the 65mm stroke may void your warranty according to Trek, but the frame handles the stress fine. @Emailsucks98 flagged that with longer stroke shocks, reservoirs can hit the downtube at full compression, so transverse reservoir shocks (Öhlins, DVO, 2025 Fox) are safer bets if you go that route. But for a stock replacement, 205x60mm trunnion mount is what you're after.
