S&S SuperstockT crankcases; made from 356-T6 aluminum; are much stronger than the OEM case. OEM cases can/may break in high performance or even stock applications; like more than a few of us found out the hard way. These S&S SuperstockT cases can be used for both stock replacement and racing applications. Important to the engine builder are the substantial savings in labor when using S&S cases. These cases come ''set up'' with sprocket shaft Timken main bearing races and cam needle bearings installed and pinion shaft main bearing race pressed in and line-honed. Additional parts that are supplied include Timken sprocket shaft bearings; cylinder studs; nickel plated case bolts; crankcase fittings; oil pressure sensor; timing & magnetic crankcase drain plugs and a special S&S design alternator stator plug clamp screw. The flywheel scrapers are machined to match the original 8-1/2" diameter flywheels. S&S cases maximize crankcase oil scavenging efficiency by using a ''ported'' design breather passageway. S&S cases are clearanced up to and including 5"; no additional clearancing for strokers will be necessary. S&S cases come complete with assembly instructions. Note: S&S crankcases for 36-54 Knuckle and Panhead models will not take OEM flywheels; pinion or sprocket shaft since late style (1955-up) Timken bearings are used in all S&S cases. 55-up shafts will not fit 36-54 OEM flywheels; S&S does not recommend machining 36-54 flywheels to take 55-up shafts. For all 36-55 B.T. applic

Note: The 36-69 S&S oil pump (MCS 519922) can be used with all 36-69 S&S crankcases. Note: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components; prior to installation. It is of importance tha
With S&S cylinder stud pattern.With S&S cylinder stud pattern. Replacement crankcases for Touring and Dyna Twin Cam engines. Offered is greater overall strength than OEM cases; especially in the front motor mount; which is an important consideration in high performance applications. CNC machined from high strength heat treated aluminum castings make these S&S cases much more cost effective than billet cases. A Timkenr style sprocket shaft bearing is used to best withstand the most demanding applications. All oil passages between crankcase and gear cover are o-ring sealed. Includes roller bearings for camshaft and pinion shaft and a Timken sprocket shaft bearing. The large cam chest allows a cam lift up to .675" without clearancing. Clearanced for strokes up to 5". Cases are compatible with stock components like oil pump; cam support plate; gear cover etc. Cases include hardware and installation instructions. Note: Includes camshafts; pinion and sprocket shaft bearings. Note: Installation of the T124 engine in a 99-05 Dyna chassis requires a oil line installation kit which is no longer available. This kit included a special transmission top cover and oil lines. Custom fabrication is required. Note: Installation of the T124 engine in a 99-06 Touring chassis requires 902299 oil line installation kit. The stock transmission cover can be re-used. Note: Crankcases for the Softail engine; with internal balancers; is not available. Note: In any and all applications the te
Chrome plated billet aluminum. With optimized pushrod cover angles for a perfect seal. Machined to accept early cork or late style quad seals. Works with up to .550" kift camshafts. Tappet block can easily be modified for higher lift cams. Upgraded replacement for 18602-80A rear and 18603-80A front. Note: On 53-E76 engine cases you will need a tappet screw conversion kit threaded for the early style cases (502990 allen head or 513555 acorn); with flat style tappet screws which will fit these late (flat) style tappets
.490" int. & .500" exh. valve lift. Modified 1100-1200 and stroked 883. Suitable for stock springs and lifters. Good midrange power. 2000-6500 RPM. Headwork necessary.
Kit with open derby cover. These ` Fit-Over' chrome dress-up trim sets are covers that fit skin-tight over the existing stock covers as a visual improvement. No removal of old cam; sprocket or primary cover required. Simply install the `Fit-Over' trim kit over the stock covers and the lower end looks like new for a fraction of the price. Kit includes primary cover; cam cover; sprocket cover trim and hardware.

Note: The OEM plastic breather is low cost but an inferior; poor quality product that will cause damage to crankcases in the breather bore since it is prone to distorting. The sooner this stock type breather is removed; the better. We highly recommended to replace it with a steel breather valve; like was used in earlier engines.
