Product overview
GM Engine Bracket
The engine bracket carrying reference 90448 177 sits in the GM Parts section of the RUIFAN catalogue. RUIFAN has manufactured parts of this type in Ruian, Zhejiang since 1994.
It is supplied to aftermarket distributors, engine rebuilders and workshops, and can be quoted as part of a wider order covering other references in the same number family.
An engine bracket locates and supports part of the powertrain assembly against the body structure. Bore spacing and section are what have to match; a bracket that locates but does not carry load correctly will fail again. The archived record for this reference holds the catalogue name, the vehicle brand block and the photograph; nothing further was stored, and nothing further is claimed here.
What this reference is used for
- Supply with the matching pan and support
- Workshop service stock
- Replacement of a cracked or distorted bracket

Who it is for
Buyers Who Order This Reference
Aftermarket distributors
Warehouse distributors and wholesalers building coverage across a whole GM number family rather than a single fast mover.
Engine rebuilders and workshops
Reconditioning shops and independent workshops that need the correct reference on the bench rather than a near equivalent.
Importers and private label brands
Brand owners who sell under their own label and need the factory behind that label to stay the same from season to season.
Problems it solves
What Brings Buyers to This Part
- The bracket is needed with the pan and the two are normally sourced from different suppliers.
- Bracket references get dropped from catalogues faster than the pans they mount alongside.
- A fatigue crack in a mount bracket has to be replaced, not welded, and the reference is no longer easy to find.
Key benefits
Why Buy 90448 177 From RUIFAN
Supplied against the reference recorded in the catalogue, not against a guessed equivalent

Produced in the plant that holds the rest of the GM Parts block, so packing and marking are consistent across a programme
Quotable as a single line or as part of a wider order across the GM Parts range
Manufactured under the quality systems recorded by RUIFAN: ISO 9001 and TS 16949
Backed by a factory that has manufactured parts of this type since 1994
Materials and manufacturing
How This Engine Bracket Is Produced
The archived record does not state a material for this reference. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against the part being replaced before production is scheduled.
Confirm construction
Material and method confirmed against the part being replaced or a supplied sample.
Form or cast
Drawn from sheet, or die, gravity or sand cast, according to what the original part is.
Machine and finish
Sealing faces, bores and threads finished to the reference.
Inspect and pack
Checked against the reference sample, then packed with the sealing face protected.
Manufacturing methods listed here are the ones recorded on the original RUIFAN services page: deep and shallow draw stamping; die casting, sand casting and gravity casting; chrome plating and vacuum metallization. The method used for a given reference is confirmed against the part being replaced.
Quality control
Quality Systems Behind This Reference
RUIFAN recorded ISO 9001 and TS 16949 quality systems on its original site. Certificate numbers and validity dates were not stored in the archived material and are supplied on request rather than stated here.
Sealing flange
Flatness across the full perimeter decides whether the part seals at all. It is the first thing to check on arrival.
Drain boss
Thread condition and squareness to the boss face, checked before packing.
Dimensional check
Against the reference sample for the catalogue number being run.
Packing
Flange protection specified per programme, because a bent flange makes a sound part unusable.
Customisation
If This Reference Is Not Exactly What You Need
The original RUIFAN site stated that the factory develops oil pans and other aluminum castings from customer-supplied samples or drawings. That route covers references that never made it into the catalogue, superseded parts whose tooling has been scrapped, and private-label variants of an existing part.
A physical sample is enough to start. Where no sample survives, a dimensioned drawing or a 3D file works. Tooling cost, lead time and ownership are agreed in writing before any work begins.
What to send with an enquiry
- The number stamped or cast into the part being replaced
- The vehicle, the engine code and the production year
- A photograph of the flange face and one of the drain boss side
- Annual quantity, or the quantity for a first order
- Destination market, which affects packing and documentation
Comparison
90448 177 Against the Alternatives
How sourcing this reference from RUIFAN compares with the other routes a buyer has.
| Option | What you get | Where it falls short |
|---|---|---|
| RUIFAN catalogue supply | The reference held in a 136-number catalogue with the archive data published alongside it, produced in one plant with one packing standard. | Fields the original database never recorded are shown as not recorded rather than filled in. |
| Original equipment channel | Guaranteed fitment and full manufacturer documentation. | Highest unit cost, and older references are progressively withdrawn from supply. |
| Local pattern part supply | Short lead time and no import handling. | Coverage is usually limited to fast movers, so the long tail of a number family stays unsourced. |
| Used or reclaimed engine bracket | Lowest purchase cost, sometimes the only route for a withdrawn reference. | Flange flatness, thread condition and corrosion are unknown until it is on the bench. |
Use guide
Identifying and Fitting 90448 177
A working sequence for confirming the reference and fitting it without a repeat leak.
- Confirm the reference against the casting number on the bracket being replaced.
- Check mounting bore spacing against the old part before installation.
- Support the assembly independently while the old bracket is removed.
- Torque to the vehicle manufacturer's specification and re-check after the first heat cycle if required.
Torque figures, sealant specification and gasket type are set by the vehicle manufacturer for the engine concerned. Follow that procedure rather than a generic figure.
Questions About 90448 177
What vehicle does 90448 177 fit?
The archived catalogue record lists this reference in the GM Parts block. No vehicle application table was stored for this reference in the original database, so none is shown. Send the vehicle, the engine code and the number from the old part and we will confirm against the catalogue before quoting.
What are the minimum order quantity and lead time for 90448 177?
Minimum order quantity, carton quantity and lead time were not recorded in the archived catalogue and are confirmed per order, because they depend on whether the reference is being run on its own or alongside other lines in the same family.
Do you have cross reference numbers for this part?
No alternate numbers were stored against this reference in the original database, so none are published here. Twenty of the 136 catalogue records do carry recorded alternates. If you hold a number you believe matches this part, send it with a photograph and we will check.
What is 90448 177 made from?
The original catalogue record did not state a material for this reference, so none is published. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against a sample or the part being replaced before quoting.
Can you supply this reference together with other GM lines?
Yes. The GM Parts block holds 11 references and they are normally quoted and shipped together. Consolidating is what makes low-volume lines viable in the first place.
