Description

*** $70 refundable core charge already included in price. *** The BB4 Prelude front/rear (BB6 rear only) spherical front upper control arm mounts set utilizes only high quality OEM mounts. Sleeves are retained in the OEM “eyelets” through a combination of interference fit and tig tack welding for redundancy. The sleeves have a shoulder on one side and can be installed with the shoulders opposed as an added measure of safety. The bearings are retained via a combination of interference and retaining compound. A c-clip provides an additional safety factor and an ID shoulder is utilized. Sleeves are machined from 4140 HT (a medium pre-hardened alloy steel) and spacers are machined from 303 stainless steel.

The standard set features Aurora COM-9T bearings. For more extreme duty, the available Outlaw Series utilizes NMB aerospace bearings at a substantially higher price point.

Note: A $70 core charge refund is offered on OEM core exchanges for this product. These parts are generally made to order as OEM Prelude mounts are getting scarce and this is a low volume seller.
