Product Details

The Strange Engineering D1549 is a Lightweight Pro Race Series steel spool designed specifically for GM 12-bolt passenger car rear ends with 33-spline Strange axles. This high-performance spool permanently locks both axle shafts together, forcing both rear tires to turn at the same speed for maximum traction in racing applications.

Key Features:

  • CNC-machined from forged 4140 chromoly steel for exceptional strength and durability
  • Lightened design reduces rotating weight to improve acceleration and performance
  • Broached specifically for Strange 33-spline axles (will not fit other manufacturers' axles)
  • Critical dimensions left oversize prior to heat treatment, then finish-machined after heat treating to meet precise specifications
  • Provides more rigid ring gear mounting, eliminating gear failure caused by case deflection
  • Eliminates differential side-gear failure common with stock cast-iron carriers
  • Forged in the USA and machined by Strange Engineering
  • Weighs 8.85 lbs

Application: GM 12-bolt passenger car rear end, 4 Series carrier gear sets

Requirements: Must use C-clip eliminator kit or aftermarket housing ends. Requires gear set designed for 4 series carrier. Spool bearings (Strange D1582) sold separately.

Strange Lightweight Pro Series Steel Spools are backed by a limited lifetime warranty, making this spool an ideal choice for serious racers seeking maximum durability and performance.

Good price, communication good but not great. Shipped promptly.

Lowest price I can find! Sent tracking number via FedEx without trouble! Would recommend!

Ordered a product and received within 2 days. Easy transaction and quick delivery.

Wow, first time I ordered and they hit a homerun with me!! Shipped same day I ordered AND was the cheapest option I had including shipping. I'll be back. Thanks for the great service!!

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.
