Product Details

The Prothane 7-301 is a rear trail arm bushing kit engineered for GM C10 and G10 trucks and vans from 1960 to 1972. Prothane's polyurethane bushings replace the factory rubber units that deteriorate over time, causing vague handling, alignment drift, and excessive suspension flex.

Unlike OEM rubber bushings that compress and deform under load, Prothane's polyurethane formulation delivers superior compliance resistance, keeping your suspension geometry precisely where it was set. This means your caster and camber alignment settings stay accurate under hard cornering, braking, and load — not just on the alignment rack.

Key Features:

  • Direct-fit replacement for GM C10 and G10 rear trail arm bushings (1960–1972)
  • High-durometer polyurethane construction resists compression and deformation
  • Maintains proper suspension geometry and alignment settings over time
  • Superior resistance to oil, grease, road chemicals, and UV exposure compared to rubber
  • Reduced suspension slop and improved handling response
  • Includes all bushings needed for a complete trail arm installation

Prothane is a leading name in performance polyurethane suspension components, trusted by enthusiasts and builders restoring and upgrading classic GM trucks. The 7-301 kit provides a long-lasting, performance-oriented solution for worn or deteriorated factory trail arm bushings.

Ordering was easy.

No problemo

Quality air cleaners. They also come with a custom wing nut. Edelbrock comes with a cheap cast wing nut.

I ordered an Alternator, it arrived on Saturday via Federal Express. It fit and works perfectly! Very happy with my purchase!! Best prices and well worth the short wait. I'd have paid twice as much locally, for a far more inferior product.

Not only did they have an great price on my part, and reasonable shipping charges, they shipped it right away.<br>I know I will be checking them for future parts.

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Items were easy to find BUT the pictures for MOOG sway bar link were of Tie Rods. So confusing I had to call Tech support for clarification of my ordered parts.

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Best price I found and VERY fast shipping. Very happy.
