If there’s one component that can make or break an off-road machine when it comes to style and performance, it’s the shocks. No matter what hop-ups you add to your ride, if it’s till rolling out on black-plastic dampers, it’s not going to
look too trick. And while those plastic boingers no doubt work fine
when new, aluminum shocks will perform even better and deliver
that superior feel longer between rebuilds. Case in point, Pro-Line’s new Ultra Reservoir Shocks—or any of PL’s deluxe dampers,
but these new scale shocks especially. Here’s why: to look
scale, shocks need smaller-diameter bodies than the fat-bodied
ULtra reservoir shocks
Deluxe looks and premium performance
for scale machines
dampers we’re used to seeing on trucks and buggies.
Making the bodies narrower is easy; the hard part is
volume compensation. When a shock is compressed, the
oil displaced by the shock shaft has to go someplace.
There are two solutions: (1) use a flexible bladder that
distorts to accommodate the oil, or ( 2) simply emulsify
(mix) air into the shock oil, which adds a compressible
element to the oil. Neither solution is ideal for a narrow-bodied scale shock, wherein the shaft diameter and
the body’s internal diameter are relatively close in size.
A greater percentage of total oil volume has to be
displaced, and the ideal way to do that is via an external
reservoir. And that’s what Pro-Line has here.
A pair of Ultra
for about $90—not
inexpensive, but if any
shocks ever looked
like they were worth
$100, it’s these.
Here’s an instant
10-point style boost, with
performance to match.
