I want to add shocks to my tandem axle trailer but the leaf springs are under the axle not on top. Will the Lippert Components Bolt-On Shock Kit like part # LC281281 work?

I do have an option for you but the Lippert Components Bolt-On Shock Kit like part # LC281281 is designed for use on overslung axles (leaf springs over axle) only. Therefore, it should not be used with the underslung (leaf springs under axle) axles that you have. The reason for this is that the shock absorbers would not be long enough and there could be interference with the axle tube.

Instead, I recommend using the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers part # RM-2450 for 3,500 lb axles (2-3/8" diameter), part # RM-2460 for 5,200 lb - 7,000 lb axles (3" diameter), or part # RM-2470 for 8,000 lb axles (3-1/2" diameter). This kit will function just like the Lippert Components Bolt-On Shock Kit and will work with both underslung and overslung axles. It also has a longer warranty of 1 year compared to the 90 day warranty of the Lippert kit.

I do have the perfect replacement option for your 2003 Bass Boat. For a 26" long double eye leaf spring, I recommend using the 4-Leaf Double-Eye Spring for 2,000-lb Trailer part #e77SR as long as your current leaf springs are 1-3/4"…

It's not uncommon for a trailer with a 29-1/2 inch axle spacing to use either 7-3/4 inch or 5-3/4 inch (or similar) equalizers but the shorter ones are more commonly used with the 25-1/4 inch leaf springs, like the ones you have, designed for…
