Pro-Line Big Bore Scaler Shocks (90mm) (2)
About this part
This is a set of two Pro-Line 90mm Big Bore Scaler Shocks. The large (nearly 11mm) bore allows the Big Bore Shocks to function correctly as true performance shocks due to the larger oil volume in the shock body. The shocks feature CNC machined Aluminum Shock Caps, Collars, Bodies, Bottom Caps, and Hard Chrome Coated Steel Shock Shafts all made to exacting tolerances. X-Ring seals (PRO6343-01 for replacements) are used as the main shaft seal for smooth, low friction action and to prevent leaks.
The Big Bores are stylish with Chrome and Black anodizing and a large P-L logo engraved into the shock cap. Pro-Line also engineered an updated dual-rate spring design made from a single spring that saves space and has incredible scale looks and performance. Optional softer and firmer dual-rate springs are available in the Big Bore Scaler Shock Spring Assortment (6343-02). The lower spring perch is captured, so you always know it will stay where it belongs. From the top mounting hole to the bottom mounting hole, these Big Bore Scaler Shocks measure out to be 90mm at full extended length and collapse down to about 64mm (when the rubber bump stop is removed) and they include extra 5mm longer Shock Ends to increase the shock length. The Big Bores come mostly pre-built (just add oil) and are designed to fit many popular crawler vehicles.

Started leaking after the second use...not impressed and would not recommend buying them.
Beautifully made shocks, but caution that the larger bore may not fit with some shock towers.
Purchased these for my Axial SCX10iii, springs provided not even close to supporting vehicle. Now I have to buy 2 sets of the spring assortment for 33$ and hope for a spring that might work.... overall quality of shocks is nice, but kind of bummed they're not even in the ballpark with the included spring and the inability to just select/buy springs by actual spring rate.
I wanted to upgrade my trx4 and like Pro-Line so I figured these fairly expensive shocks would be good but the springs that came with them won’t even hold up the truck unless I adjust the “pre-load adjustment” all the way to the bottom of the threads. Kinda disappointed. Now it looks like I’ll have to buy the the spring assortment pack......
Four verified owners rate these 90mm Big Bore Scaler Shocks between 2 and 4 out of 5. Reviewers generally describe the shock build quality as good. The most common complaint is that the included springs are too soft for the vehicles, with one reviewer needing to bottom out the pre-load adjustment to support the truck, and others needing to buy a separate spring assortment to get a usable rate. Reviewers also note that springs cannot be selected by spring rate directly. One reviewer reports leaking after two uses, and another cautions that the larger bore may not fit some shock towers.
