Hey GP460/G62 owners, Tired of your unreliable GP460 clutch springs? Tired of your engine revving to the moon while cruising at 5-10mph? Tired of burning through clutches? I figured I’d post a how to on making your own “clutch saver” Low engagement 460 clutch springs for free.
A little background on this. I’ve always disliked how high the red (and yellow) spring 460 clutches engaged. I understand the benefits of the high stall springs, but for me, having the engine scream away while cursing just wasn’t enjoyable. It definitely wasn’t worth the second or two of acceleration gain. And you definitely don’t need to spend the $14 bucks on DDM “clutch saver” springs.
Some time ago I saw a post from another member on here who mentioned heating the OEM red or yellow springs to reduce engagement RPM, so I figured I’d give it a try, and guess what. It works great! It’s almost exactly comparable to the DDM clutch saver springs.
The process involves removing your current 460 clutch pads and springs (You do not need to remove the whole hub from your motor) and heating the springs with a propane/map gas/or possibly butane torch. Until the paint turns white and the metal is cherry hot, and allowing them to cool slowly. Finally, reassemble in reverse order.
the idea is to remove the hardening of the steel springs by heating. Heating the steel and cooling slowly increases the grain size meaning the atoms will be farther away from each other thus reducing the hardness.
An advantage you this process is that the steel also becomes less brittle which means less chance of broken springs.
sorry for the lack of photos on this post, hopefully this helps some of you guys.
