SuperSprings Rear Axle Helper Springs for 2016 Toyota Tundra 4WD Towing 7800-lb Car Hauler

Question

Question:

Good afternoon from Columbia, Missouri! Ive got a 2016 Tundra 4x4 5.7L that tows a 2018 Big Tex auto trailer with my old Land Cruiser on it. Total GVWR of trailer with Land Cruiser is about 7,800. Would you recommend the SSR-610-47 SumoSpring over the lighter version and the heavier duty version? I just want to get rid of a couple of inches of sag for our trip to Utah in July. Thanks!

Helpful Expert Reply:

Your Big Tex trailer with a 7800-lb loaded GVWR probably has tongue weight (TW) in the range of 900- to 1100-lbs so the SuperSprings rear-axle kit # SSR-610-47 you referenced is what I recommend. This 1500-lb-rated jounce spring kit will lend enough support to the rear suspension on the Tundra without being too stiff.

Since the exact position of the Land Cruiser on the trailer can affect your tongue weight having the little bit of extra capacity is a good idea.
