this product has been the "go-to" shock

July 03, 2014
Up until recently, this has been "the" shock to use for over-all performance and ride quality. We had one fail (leak, and then quit) while still under warranty and Speedway sent us a replacement. We have no complaints with Speedway and the level of customer service provided, but the quality of this particular product from "Pro Shock" seems to be diminishing. The kicker is that a year ago, this shock was $47. Now the price has jumped to $75. I don't understand that kind of jump in that short period of time. The representative at Speedway assured us that it is an increase passed on from the manufacturer and out of necessity passed on to the consumer. It looks like Pro Shock is pricing itself out of the market and we will be forced to find a suitable replacement for future use.
Pros:
  • great success with this shock
Cons:
  • suddenly too expensive
No, I would not recommend this product.

Merchant Response:

Please note that this shock has incurred a price increase. Due to such, Speedway Motors has developed an alternate for consideration in shock # 910-46214 that has the same length specs and can be used in place of the SM300.

Replaced the old friction shocks with a pair of these - what difference! I was worried they might be too harsh, but the ride is perfect. One of my best upgrades so far.
Pros:
  • Look Great
  • excellent ride characteristics
Yes, I recommend this product.

Mounting hole on the SM300s for use with Speedway Suspension Kits. I have the 91639510 suspension kit which uses the 91036105 lower shock mounts. I assumed that the SM300s would fit on this lower mount, but they do not. Do I need to remove the pressed in steel bushing or is there something that I'm missing? Is ther a special shock to work with your suspension kits? Thanks, Dan Shea

Yes you need to remove the sleeve in the shock to allow these parts to work correctly together.

These shocks are oil filled and 50/50 compression and rebound. Order correct length to allow 50-60% of stroke for compression at ride height.
