Product Details

The SPC Performance 10523 zinc alloy axle alignment shims provide a fast, accurate solution for aligning the front or rear axles of tandem trailers and heavy-duty trucks. Measuring 3" x 6" with a 1.5° taper, these shims are engineered to meet the demanding requirements of over-the-road commercial applications.

Key Features:

  • Zinc Alloy Construction — Offers superior hardness compared to standard aluminum shims, delivering performance on par with premium manganese bronze shims
  • Improved Compression Strength — Significantly greater resistance to compression versus aluminum, reducing deformation under heavy load
  • Precise 1.5° Taper — Engineered for accurate axle angle correction on most popular tandem trailers and trucks
  • 3" x 6" Footprint — Sized for broad compatibility with common heavy-duty truck and trailer leaf spring applications
  • Pack of 6 — One part number supplies six shims per box, ideal for multi-axle alignment jobs

SPC Performance (Specialty Products Company) has been a trusted leader in alignment parts since 1975. The 10523 zinc shims represent a cost-effective upgrade over aluminum shims, combining greater durability with the precision needed for professional-grade axle alignment work.

This was my first order through autoplicity but I doubt it's my last. They had the best price by far on the K & N air filter I was looking for. The price was right, the filter was packed well, and the shipping was fast. No hassle transaction. Great job autoplicity!

Best price on a timken wheel bearing I could find. I will be doing business with them again.

Really good prices and fast delivery.

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

good stuff

Really great prices with cheap shipping, best I could find. Can't wait to use the bed extender for hauling my kayaks!

Received the spider gears a day late due to weather conditions. Overall great!
