This is the sought after ratio for Sprite and Midget owners who want to reduce engine revs at freeway speeds. This ratio,  3.7:1, was introduced in 1977, 2 years after the MG Midget had the Spitfire 1500cc driveline installed. This eased the engines revs at speed and provided 17.9 mph per each 1000 rpms in top gear.

This differential includes a new 3.7 ring and pinion gear set or a good used set.

These differentials are rebuilt with all new bearings, cross pins, thrusts, collasible spacer, and seals.  The "Core Charge" will be refunded after we determine that your old diff assembly is rebuildable.   NOTE: ONLY THE LATEST STYLE BTA548/549 DIFFERENTIAL HOUSINGS WILL ACCOMODATE THE 3.7 CROWN WHEEL AND PINION. THE EARLY TYPE CASES WITH THE SIDE FILL PLUG ARE NOT REBUILD/CORE CANDIDATES FOR THIS GEAR SET AS HOUSING TYPES MUST MATCH - CORE GEAR RATIO IS NOT IMPORTANT.

 

 

 
 
Question:
Can you do different gear ratio like a 3.08
Answer:
Hello.    BTA521 3.55 ratio is the smallest.

Hope that helps
