– @6.0V 0.20/60° sec – 158 oz-in (11.3 kg-cm)

#3
ProTek RC 160T
#3 is the pure performance – well at least the highest I would recommend going ProTek RC 160T (Low Profile)
– Operation range 4.8V – 7.4V
– @6.0V 0.08/60° sec – 216 oz-in (15.5 kg-cm)
– This is what the top racer would be using but for the price, it’s hard to recommend it over EcoPower WP115T Low Profile
– Full aluminum case
– Comes with one of the best aluminum servo horns on the market
– The bottom line is it will be hard for you to be disappointed with this servo in your slash 4×4

#4
Traxxas 2075X

#4 is the #1 recommended replacement by Traxxas – Just hard to disagree with the manufacturer Traxxas 2075X (the metal gear makes it a great upgrade over stock)
– @6.0V 0.17/60° sec – 125 oz-in
– not really much to say – This is just like the servo that came in your Traxxas Slash 4×4 but beefed up with metal gears
– around $50 IMO a bit overpriced for the performance – you can get double the torque with EcoPower WP110T (High Torque) and cost less
– Both servos are waterproof

Any 25T off-brand servo
#5 on this list is for the price and just a servo to make things work till you can afford the ones above.
– Operation range 4.8V – 6.8V
– The rating of these servos are good but hard to trust off-brand numbers
– Around @6.0V 0.15/60° sec – 290 oz-in
– Metal Gear and waterproof
– usually can find under half the price

The stock voltage of the BEC is 6.0V - this means even if you run an 11.1v lipo your servo will run at 6.0V - that is why if you look at the list all stats are for the 6.0v range.
