The JConcepts Traxxas Slash 4x4/Stampede 4x4 Monster Truck Suspension Conversion Set includes carbon fiber front and rear shock towers, aluminum shock stand-offs, body mount adapters and aluminum caster blocks. Using this combination of parts along with other parts (not included) help build the ultimate monster truck from two of either of the most popular Traxxas vehicles on the market.

The 4mm long-stroke front shock tower has been designed to use a longer Traxxas shock (not included) for better shock geometry in rugged conditions. The carbon material improves response of the suspension and provides a stable setting for the included aluminum body mount adapter. The rear tower, also in 4mm material, utilizes the stock geometry but with the addition of carbon fiber and precise machining, tightens up the feel of the rear suspension. The included aluminum shock stand-offs position the shocks at an advantageous angle and allows the shocks to work as designed.

All the changes to the geometry conclude with the new caster blocks. The camber link position has been revised and extra material trimmed to allow smaller diameter wheels needed for monster truck wheels and tires. The machined aluminum blocks are durable and are finished in a high-gloss black anodizing. The set includes heavy-duty 3mm hardware to secure the transformation. This set of parts, combined with the list of items below complete a conversion to the ultimate monster truck for racing, bashing and free-styling.

In the hands of Fred “Free-style” Reep, the conversion set has won the NR/CTPA World Championships and Spring Nationals in the highly competitive Free-style division. At the R/C Monster Jam World Finals in Las Vegas, Nevada, Fred once again locked down 1st place during day 1 to win the Free-style competition. During day 2 at the World Finals, Dan “The Man” Wyatt won a thrilling competition with the JConcepts conversion set in front of a packed arena.

JConcepts Traxxas Slash 4x4/Stampede 4x4 Monster Truck Suspension Conversion Set
I can't recommend the JConcepts Suspension Conversion Set more, than to say it's fantastic. I like it so much, I'm ordering a second. However, it does need to be mentioned that the Slash & Stampede 4x4s are NOT the only vehicle this is compatible with. I installed the first one on my Rustler 4x4, and, paired with either the Traxxas TRA6815R, or RPM73932 (especially the RPM), body mounts, plus any body designed for the Traxxas Jato, and you'll have yourself an almost-proper "true" stadium truck. Stepping it up another notch, add 15mm hub extensions, along with 2.2" stadium truck wheels, and now you WILL have a true 4WD stadium truck. Getting back to that second suspension conversion kit I mentioned, that will be going on my Slash 4x4.
