Leaf spring suspensions are tough but not exactly smooth. These Roadmaster Comfort Ride shock absorbers use nitrogen-charged gas shocks to absorb the road vibration that leaf springs alone can’t handle. With a 17-1/2" extended and 11-1/2" compressed length, each shock keeps the trailer steady and reduces bouncing, chucking, and porpoising on uneven pavement. The result is a ride that feels controlled instead of jarring, even with a fully loaded trailer.
A trailer that rocks side-to-side can make towing feel tiring. These shocks mount at a 15-degree outward angle and use adjustable frame brackets that set them nearly vertical for maximum leverage. That setup controls up-and-down movement during both compression and rebound while also limiting lateral sway. The trailer tracks straight behind the tow vehicle, even when the road isn’t perfect.
Roadmaster didn’t stop at design—they validated it. Each Comfort Ride shock system went through Finite Element Analysis and real-world durability testing at the Navistar Proving Grounds. The result is a tested and trusted setup that holds up mile after mile, so your suspension upgrade keeps working long after the first trip out.
You don’t have to cut or weld to get a better ride. The kit bolts on using included tie plates, hardware, and adjustable mounting brackets that fit tandem-axle trailers with 2-3/8" diameter (typical 3,500-lb) axles. The upper brackets mount to the trailer frame, and the shocks connect between the tie-plate extensions and the frame brackets for a solid, aligned setup that works with either overslung or underslung axles.
This complete kit includes four heavy-duty shocks and all the hardware needed to upgrade both axles. Once installed, it smooths out the ride, helps protect your trailer’s structure and contents, and adds confidence to every haul. It’s a simple way to make towing feel less like work and more like travel.

Great. We’ve towed all over the country about 13,000 miles, and we’re still pleased with the ride.
