Hamskea PRS Exchange Spacer — Dial In Your R7's Torque Tune Position
The Hamskea PRS Exchange Spacer is a precision torque tuning component for the Hamskea R7 arrow rest. It is a single spacer — available in 0.3", 0.4", or 0.5" thickness — from Hamskea's PRS Exchange Torque Tune Kit system. By inserting one or more spacers between the rest assembly and the dovetail clamp on the bow, you move the R7 further from the riser to find the position where your bow is most forgiving of shooter torque. Stackable from 0.3" through 1.5" of total offset, these spacers give you precise, repeatable torque tune adjustment without complexity or extra hardware. Available in Right Hand and Left Hand configurations.
Key Features of the Hamskea PRS Exchange Spacer
Torque Tune Your R7 Without Pulling Axles
Torque tuning moves the rest's position relative to the riser to find the point where the bow is most forgiving of hand torque during the shot. On the R7, this is accomplished by stacking PRS Exchange Spacers between the rest body and the dovetail clamp — a clean, straightforward process that requires no axle removal and no shimming inside the cam.
Three Sizes — 0.3", 0.4", 0.5"
Each spacer is sold individually so you can build exactly the offset you need. Start with a 0.3" spacer and test. Add more if your groupings improve. Remove one if you've gone too far. The modular system lets you experiment systematically rather than committing to a fixed position.
Stackable from 0.3" to 1.5"
Any combination of 0.3", 0.4", and 0.5" spacers can be stacked to achieve total offsets between 0.3" and 1.5" in 0.1" increments. This gives you a wide enough adjustment range to find the optimal torque tune position on virtually any bow platform the R7 is mounted to.
Fits Between Rest Assembly and Dovetail Clamp
Installation is direct — the spacer seats between the R7 rest body and the bow's dovetail/Integrate clamp. No additional hardware is needed. The spacer is held securely in position by the existing clamp tension.
Right Hand and Left Hand Versions
Available in both dexterity configurations. Select the correct hand orientation for your bow when ordering.
Who the PRS Exchange Spacer Is Built For
- Hamskea R7 users who want to explore torque tuning for improved consistency and tighter groups
- Archers experiencing left/right shot inconsistency that isn't resolved by windage adjustment alone
- Anyone who purchased the PRS Exchange Torque Tune Kit and needs additional individual spacers for extended adjustment range
- Technical archers who tune methodically and want incremental control over rest position

Why Extreme Outfitters Recommends the PRS Exchange Spacer
Torque tuning is one of the most effective and least talked-about adjustments in compound bow setup. Moving the rest forward from the riser changes the mechanical relationship between the bow's torque characteristics and the arrow's departure point — and for some bows and some shooters, the right torque tune position is the difference between 1-inch groups and 3-inch groups at distance. The PRS Exchange system makes this adjustment accessible without complexity. If you're running an R7 and you haven't explored torque tuning, a 0.3" spacer is an inexpensive way to find out if your setup has room to improve.
Frequently Asked Questions — Hamskea PRS Exchange Spacer
What is torque tuning and why does it matter?
Torque tuning adjusts the rest's forward/backward position relative to the riser to find the point where the bow is most forgiving of grip torque during the shot. At the optimal position, left/right inconsistencies caused by minor variations in hand pressure are minimized, resulting in tighter groups and more consistent arrow flight.
Which size should I start with?
Start with 0.3" as your baseline. Shoot groups, note your results, then add another spacer if your consistency improves. Work your way forward in small increments. Most setups find an optimal position between 0.3" and 0.9".
Is this compatible with all R7 mounting styles?
Yes. The PRS Exchange Spacer works with both Integrate-style dovetail mounts and Universal Bracket mounting configurations for the R7.
Do I need to remove the rest to install a spacer?
Yes. Loosen the dovetail clamp, insert the spacer between the rest body and the clamp, and re-tighten. No bow press is required. Re-check windage and elevation after any torque tune adjustment as position may shift slightly.
Can I stack spacers from different sizes?
Yes. 0.3", 0.4", and 0.5" spacers can be mixed and stacked in any combination to achieve your target offset from 0.3" through 1.5".
Is this the same as the full PRS Exchange Torque Tune Kit?
No. The full kit includes all three spacer sizes (0.3", 0.4", 0.5") together. The individual PRS Exchange Spacer is sold as a single spacer in one size — for archers who need additional range beyond what the kit provides, or who want to replace a specific size.
