60" DIY Trailing Arm Kit

60" DIY Trailing Arm Kit

More travel, more control—designed for speed, crawl, and serious abuse.

This 60" DIY Trailing Arm Kit is built for off-roaders who are pushing the envelope—whether you're bombing through desert whoops, crawling technical rock gardens, or chasing podiums in Ultra4. It's the evolution of our classic 55" kit, with added length for more stability, more control, and a smoother shock cycle when the terrain gets rough.

Why go 60"? That extra length isn’t just for bragging rights—it directly translates to better wheel travel and improved handling. The shock mounts are placed 1" below the centerline to protect the shock shaft and eliminate the need for wobble stops, while the motion ratio is dialed in for max performance across all types of terrain. You’re not compromising between speed and crawl—you’re getting both.

It’s all DIY, so if you're the kind of fabricator who'd rather burn your own welds than trust a catalog solution, this kit is right up your alley. We send you the clean, laser-cut pieces, and you take it from there. Weld it up, paint it how you want, and make it yours.
