Otto MittelVerified owneron Pro-Line 2.2" Dual Stage Rock Crawling Foam Inserts (2)

Pain in the ass to mount on jconcepts raptures. Had to do a little trimming of the inner foam. Once installled they work like Magic. No more squatting during high speed cornering or sidehilling. Axial bomber, 7.5pounds.

Henry SimasVerified owneron Pro-Line 2.2" Dual Stage Rock Crawling Foam Inserts (2)

I have these foam inserts installed in a set of Super Swampers with the SSD RC 2.2 D Hole PL Beadlock Wheels. This set-up is installed on a 12 pound Traxxas TRX4. I have had these for over a year with no signs of breakdown they still perform like new. I also store my truck sitting on its tires and never get flat spots I would recommend these to everyone

Louis CominielloVerified owneron Pro-Line 2.2" Dual Stage Rock Crawling Foam Inserts (2)

This is a must on 2.2 tires, makes a huge difference. Tire holds it's shape and you get the ground clearance you pay for. Pain in the butt to install!!!!! Someone should make a youtube video on how to install in an easy way if it exist.

Really good two stage foams for my heavier 2.2" rig.

What reviewers say

Four verified owners rate these dual-stage foam inserts 4 to 5 out of 5. Reviewers agree the inserts help tires hold their shape, reduce squatting during cornering and sidehilling, and perform well on heavier 2.2-inch rigs, including a 12 pound Traxxas TRX4 and a 7.5 pound Axial Bomber. One owner reports no visible wear after over a year and no flat spots from storing the truck on its tires. The recurring complaint is that installation is difficult, particularly on JConcepts Raptor wheels, and one reviewer notes trimming the inner foam was needed. The reviews all describe the Pro-Line 2.2-inch Dual Stage Rock Crawling Foam Inserts (2) variant. The sample is small.

  • + Tires hold their shape
  • + Reduces squatting in cornering and sidehilling
  • + Durable, no visible wear after over a year
  • + No flat spots from storage
  • − Difficult to install
  • − Inner foam may need trimming to fit
  • − Installation guidance is hard to find
