Losi XXX-CR, Team Associate B4, Kyosho, Tamiya...basically most 1:10th shocks will fit, some better then others without adjustments.
Your looking for 75mm front and 95mm rears or close to that.
AE factory shocks are £40 per pair, Losi run about the same, Tamiya are £84 for a set of 4. All work out to be about £80 for a full set.
The X pro shock set is £52 for a full set and are really quite good, they do compare well with the others.
You could try changing springs... all 1:10th brands should fit an X Pro shock set 55mm fronts 75mm rears.
Also when trying for big air.. remember to control you're decent with throttle as you are in the air...try for as flat a landing as possible.
No matter what shocks or car you have if you plough the front end or slap the rear end into a hard surface it's gonna cripple you somehow eventually
