These are new material boots. They are designed to temporarily stretch over the ball-n-trunion housing so they can be installed without disassembling the ball-n-trunion and without trying to push it through the housing. The stretch to over 500% their original shape without damage.
Using the installation tool, the boot will install in a matter of minutes once the shaft is removed from the vehicle. This certainly a job of the do-it-yourselfer or the home hobbiest. If you don't want to pay for the installation tool, you can use trimmed down ATF fill funnel (I did on my first boot install).
In the past, mopar owners would have to spend a lot of money to solve the problem of a cracked or torn boot. Slip Yoke conversions can range from $200 to over $300, plus the time spent dealing with a driveshaft shop can be significant.
For B-body and C-body owners, converting to a 1965 cable shift B/RB automatic is even more expensive and time consuming. A-body owners don't have a similar option for G/RG/LA cars, and for the crowd of pre-1962 mopar owners, converting emergency brake systems adds tremendous complexities.
I've got 30,000+ miles on one of the replacement boots and it is showing no signs of wear.
