Recommended Timbren Rear Suspension Enhancement System for a 2017 Toyota Tacoma with 4 Leaves


Which Timbren model number will fit better and does both models come with installation hardware? TORTUN4? or TORTUN4L? 2017 Tacoma Off Road with 3in level kit / 4 leaves.

For your 2017 Toyota Tacoma, I recommend using the Timbren Rear Suspension Enhancement System part # TTORTUN4 because you have 4 leaf springs. If you had 3 leaf springs then you would want to use the Timbren Rear Suspension Enhancement System part # TTORTUN4L.

The bump stop attaches to the top of the leaf spring pack and makes contact with the bottom of the frame rail. If this distance has been altered with the leveling kit you have installed on your truck, then you will need to use increments of the part # A25723-90AH00 (1") and part # TA25722-90P00 (1/2") until there is 1/2" to 1" of space from the top of the Timbren spring to the bottom of the frame rail.

The hardware for the Timbren Rear Suspension Enhancement System is included in the kit. However, the bolt used to attach the bump stop is 1-1/2" long therefore, if the Timbren spacers are installed you would need to match the spacer thickness to your new bolt length. For example, if you installed one 1" spacer and one 1/2" spacer then the new bolt you would need is a 3" long M10 bolt which can be acquired at most local hardware stores.

I have attached an installation and review video of the correct Timbren's for you as well.
