You can use both the RoadActive Suspension Enhancement Kit # RAS4611 and the Timbren Suspension Enhancement Kit # TGMRCK25D at the same time. The Roadmaster kit will take care of the travel the initial travel of your suspension, the Timbren will just support the suspension at the end of travel. Both will work great for enhancing your suspension throughout the complete travel of your suspension. They will not work against each other.

I have ordered and planning installing both the Timbren and the road active suspension for my 2020 F150 king Ranch. Do you think I will need the Timbren extension kit and how much gap should I leave between the Timbren bottom plate and the rubber device on the install? Should I install the Timbren first and the road active second for ease of installation ? It is order # 122721120

@RichardM Is there a reason you are wanting to do both at same time? I would first recommend trying the RAS and then IF you think you need more maybe try the Timbren. If you end up needing more than one kit you are probably over capacity.

@JamesonC I followed your advice and installed the RAS 3611 YHD. It did not come with a bump stop spacer that i have seen in the installation video. Is it supposed to have one of those?

@Jameson, in Lieu of the Timbrens, would sumo springs work with the RAS system? Do you recommend it?
