Lightweight Aluminium Rings for SD and BD Platforms

Produced by Yokomo, the SD-501R Aluminum Differential Joint Rings are designed to shield axle parts inside diff housings and spool joints. Intended for SD/BD series cars, they deliver a snug fit and increased wear resistance. The light aluminium construction reduces unsprung and rotating mass without compromising strength.

Chassis Compatibility Guide

The Yokomo SD-501R rings are compatible with many chassis types, such as DP-DIB2, DP-DIB2A and DP-DIB, among others. This compatibility simplifies installing them into a range of vintage and modern SD/BD style builds.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will these rings fit my DP-DIB2 diff?

Yes, the SD-501R is listed as compatible with DP-DIB2 style diffs, provided the housing uses the standard joint dimensions.

Do they reduce rotational weight noticeably?

Compared with heavier steel parts, the aluminium rings cut rotating mass which can improve acceleration and response on tuned setups.

How should I maintain these parts?

Keep them free of grit and inspect for wear after hard running; a light corrosion inhibitor works well for long term care.

Are special tools needed to fit the rings?

Basic hand tools are sufficient, but use a fine pick to remove old seals and a soft-faced press or careful tapping to seat the rings evenly.
