Product Details

The Wiseco RCS38100 is a tapered piston ring compressor sleeve precision-sized for a 3.810-inch (96.77mm) bore. Forged in-house in the USA and machined from the same forgings used for Wiseco's performance pistons, this sleeve is an essential engine assembly tool built to professional standards.

Unlike traditional adjustable band-style ring compressors, this bore-specific tapered sleeve design guides piston rings smoothly and evenly into the cylinder, significantly reducing the risk of bent or broken rings — especially the thin, high-performance oil rings common in modern performance builds. Compatible with pistons from any manufacturer, it's a versatile addition to any engine builder's toolbox.

Key Features:

  • Bore-specific fit: 3.810 in. / 96.77mm bore size
  • Machined from Wiseco forged sleeve stock for maximum strength and durability
  • Hard anodized and Teflon coated for low friction and long service life
  • Smooth tapered radius compresses piston rings evenly for damage-free installation
  • Greatly reduces difficulty when installing thin, high-performance oil rings
  • Compatible with pistons from any manufacturer
  • Forged and manufactured in the USA
  • Black anodized aluminum construction

The Wiseco RCS38100 tapered ring compressor sleeve is a must-have tool for any performance engine assembly. Proper piston installation starts with the right compressor — this sleeve makes the process fast, safe, and repeatable.

I bought an Exedy Organic Clutch at the best price I could find. Shipping was also prompt. Legit dealer, good business.

Product was as described, shipping was fast, and communication was excellent. Plus I saved $$. Thanks Autoplicity! I'll be a repeat buyer and referral source.

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

Excellent.

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

I ordered a Thule 9002 Raceway Bike Carrier on Sunday, April 8 and received the product by Fedex on Wednesday, April 11 with just regular shipping. That is fast service. And the price was $43 cheaper than any other site on the internet (including shipping). I haven't had a chance to use the bike carrier yet but it appears to be new and as advertised with no issues as of this writing. I would definitely recommend this retailer for your next purchase.
