$110.00

(2 customer reviews)

This kit features upgraded 3″ wide blocks designed for your LCA bow press. These blocks should be installed on any copper-colored LCA press. By upgrading, you’ll replace the narrower 2.5-inch blocks with the wider 3-inch blocks, which accommodate the latest, wider limb compound bow models on the market. Installing these blocks is simple and can be completed by following a few easy steps.

1. Product Overview

The Block Kit Upgrade is a new interchangeable system for Last Chance Archery bow presses. The block is the base where press fingers mount, and the new kit widens that base from 2.5 inches to 3 inches.

Why Upgrade?

  • Some new compound bows have extra-wide limbs.

  • A wider base ensures the press fingers can spread far enough to safely compress these bows.

  • The upgrade also includes larger bolts (5/16”) for added strength and durability.

⚠️ Note: Not all archers will need this upgrade. For most bows made in the past 20 years, 2.5″ blocks are sufficient. Only very wide-limbed bows require the new 3″ block.


2. What’s Included in the Kit

  • (2) Aluminum Blocks (3” wide)

  • (2) Nut Plates

  • (2) Spring Steel Plates

  • (4) Mounting Bolts (5/16”)

  • (2) Spring Steel Bolts


3. Tools Required

  • Flathead screwdriver

  • Torque wrench (set to 220 inch-pounds)

  • 1/8” Allen wrench

  • 5/32” Allen wrench

  • 3/16” Allen wrench (T-handle recommended for ease)


4. Step-by-Step Installation

Step 1: Remove Existing Block

  1. Use a flathead screwdriver to pry out the plastic cap on the press end.

    • Heat may be required if the cap is stubborn.

  2. Use a 1/8” Allen wrench to remove the screw securing the spring steel plate.

  3. Use a 5/32” Allen wrench to remove the two mounting bolts securing the block.

  4. Remove the nut plate from inside the press arm.

  5. Take off the old 2.5” block.


Step 2: Install New 3” Block

  1. Position the new block with the small hole for the spring steel screw facing outward.

  2. Insert the new nut plate inside the press arm:

    • Narrow side faces forward.

    • Dimple faces outward.

  3. Insert the new 5/16” bolts through the block into the nut plate.

  4. Push the block all the way forward before tightening.

    • This creates clearance for accessories like the LCA Draw Board.

  5. Tighten bolts with a 3/16” Allen wrench until snug.

  6. Final torque bolts to 220 in-lbs with a torque wrench.

  7. Attach the wider spring steel plate with the 1/8” Allen wrench.

  8. Reinstall the plastic cap.


Step 3: Repeat on Opposite Side

  • Perform the exact same steps for the second press arm.

  • Ensure both blocks are aligned and tightened correctly.


Step 4: Reinstall Press Fingers

  • Press down on the spring steel plates and reinstall the press fingers.

  • The 3” blocks allow wider maximum spread while still narrowing to the same range as the original 2.5” blocks.


5. Final Check

  • Confirm both blocks are secure and evenly installed.

  • Verify press fingers move freely and achieve the wider spacing needed.

  • Your press is now ready to handle bows with wider limb designs.


6. Notes & Support

  • Upgrade applies to all copper or brown-colored presses that use aluminum machine-mounted blocks.

  • For EZ Green or Pack-N-Go presses, a different pin kit upgrade is available.

  • As of late 2023, all new presses are being manufactured with 3” blocks as standard.

    works perfectly

    Great product, very easy to switch out with the old kit!

  2. Joseph Black

    The best upgrade!!!

    The block kit allows me to safely get the fingers lined up on the limb. This works for all bows. If you have a newer Mathews bow this is a must! Don’t forget the Mathews fingers!
