Shock Kit for 3 Inch Round Axles

Question:

I have a Montana 357THT toy hauler and would like to add these helper springs to the rear axle. I only have 4 inches of space above the axle to the frame. These say 5 inches tall. Is that with of without the spacers?

The SumoSprings Trailer Helper Springs TSS-101-40 are 5" tall without the spacers which would be too large for your application.

Assuming you have a 3" round axle you may want to take a look at the Lippert Components Bolt-On Shock Kit w/ Heavy Duty Gas Shocks # LC281281. These are designed for leaf spring suspension systems with 5,200 lb to 7,000 lb axles, which typically have 3" round axles.

I have added links to the installation instructions and a video review for you to check out as well.
